DISCLAIMER 

Embry-Riddle Aeronautical University (ERAU) is not responsible for any 

errors or omissions of this document. While the DA42-L360 Standard 

Operating Procedures (SOP), and associated checklists are ERAU’s 

guidelines for the safe operation of the DA42 L360 aircraft, they are not the 

sole source of information regarding the operation of this aircraft. The pilotin-command 

must refer to the Diamond DA42 L360 Pilot Operating 

Handbook for further information. 


DA42 L360 SOP xiii 



DA42 L360 SOP 1 

INTRODUCTION 

The procedures outlined within the DA42-L360 Standard Operating 

Procedures (SOP) have been reviewed and accepted by the Embry-Riddle 

Flight Training Department for use in the Embry-Riddle Aeronautical 

University (ERAU) Flight Training Program. 

The Standard Operating Procedures explain the intended use of Preflight 

and Normal procedures used in operating the DA42-L360 aircraft and 

provide a detailed explanation of individual checklist items, Standard 

Operating Procedures (SOP), and recommended techniques used to 

accomplish them. 

The DA42-L360 SOP has been developed utilizing generally accepted 

industry procedures and several reference texts and manuals. Industry 

sources include the Diamond Aircraft Company, the National Aeronautics 

and Space Administration (NASA), the Federal Aviation Administration 

(FAA), United Airlines, and Northwest Airlines. 

Warnings, Cautions, and Notes found throughout the SOP. The following 

definitions apply: 

WARNING 

Operating procedures, techniques, etc., that, if not 

carefully followed, could result in personal injury or loss 

of life. 

CAUTION 

Operating procedures, techniques, etc, that, if not 

carefully followed, could result in damage to equipment. 

NOTE 

An operating procedure, technique, etc, that is 

considered essential to emphasize. 


2 DA42 L360 SOP 

ERAU CHECKLIST POLICY 

A critical element in the development as a professional pilot is in the 

training in checklist usage and discipline. Pilot deviations from standard 

operating procedures are the number one crew related cause of hull loss 

accidents. Many of these accidents and incidents are the direct result of 

the improper use of or lack of training in checklist usage. Therefore, 

checklist usage and discipline must be emphasized in our crew 

environment to help ensure safe and efficient flight operations at Embry- 

Riddle Aeronautical University and in preparing students for careers as 

professional pilots. 

All checklists are accomplished by either a Do/Verify or 

Challenge/Response methodology. The Read/Do methodology has been 

eliminated as an acceptable means of conducting the checklist. The 

principle advantage of the Do/Verify philosophy provides for setup 

redundancy. 

Setup redundancy occurs when the aircraft is configured from memory 

(Flow) and the checklist is used only to verify that all items have been 

accomplished properly. Therefore, if an item is missed in a flow check, a 

second opportunity exists to catch the missed item during the checklist 

procedure. While the Do/Verify method may require additional dry time to 

learn the flows, when practiced and perfected, the level of a truly 

professional pilot will be attained. Note flows should be silent and checklist 

items shall be conducted out loud. 

Consistent with the Do/Verify philosophy, the checklist must be used to 

back up the flow even though a memorized flow check shall be employed. 

A memory-guided checklist (no verification of the flow with the checklist) is 

unacceptable and not consistent with safe flight operations. In addition, a 

visual verification that a switch or control is in the correct position when 

accomplishing the checklist is mandatory (not to be verbalized). 

The only exception to the Do/Verify philosophy occurs when conducting 

Abnormal Checklist items. These items are not performed as part of a flow 

but as Read/Do. The initiation and completion of all checklists shall be 

announced by the executing crewmember or the challenging crewmember 

in the case of a Challenge/Response checklist (e.g., “Before Start 

Checklist”.......“Before Start Checklist Complete”). 



The initial callout allows the crew to concentrate on the checklist being 

performed, and the completion call is a necessary action to allow the crew 

to mentally move to other areas of operation with reassurance that the 

previous checklist is complete. 

Use the specific wording of each Challenge and Response for all normal 

situations. When an item allows a choice of responses, such as Pitot 

Heat...Off (On), the choices are listed and the appropriate response shall 

be given. The first response is the most probable control position, while the 

response in parentheses is the least probable control position. When a 

checklist response does not allow for the use of a specific switch position, 

the following terms should be used as a response: 

• SET: Indicates that panel switches/knobs must be moved to or in the 

appropriate position. 

• CHECK: Indicates that controls/other systems must be 

evaluated/tested. 

• INSPECT: Indicates that equipment must be visually checked for 

damage and security. 

Any interruption in accomplishing a checklist (other than for Final Items or 

routine communications) requires the checklist to be repeated to ensure 

prevention of any checklist item from being missed as a result of the 

interruption. 

The Sterile Cockpit concept shall be employed on the ground and in critical 

phases of flight to help ensure that critical checklists are accomplished 

correctly. Sterile cockpit refers to the elimination of nonessential 

conversation, excluding conversation necessary for safe flight operations or 

flight instruction. Finally, clear communications shall be used when 

changing system configuration or during exchange of the flight controls. 



INTRA-COCKPIT VERBAL COORDINATION 

In addition to reading back communications with ATC, Hear-Backs shall be 

employed between the student and the instructor in the airplane. This is to 

help ensure a common understanding by one flight crewmember that 

repeats the instructions verbally and obtains agreement on the content and 

intent from the other flight crewmember in the airplane. When flight 

crewmembers verbally confirm their understanding of the instructions, any 

errors or misunderstandings can be discovered and corrected, thus 

preventing any hazardous situations from developing. This verbal 

coordination shall be accomplished: 

(1) When ATC issues taxi instructions for departure, the flight crew should 

refer to the airport diagram, coordinate verbally and agree on the 

assigned runway and taxi route, including any instructions to hold short 

of, or cross any intersecting runways. 

(2) When ATC issues landing instructions, the flight crew should 

coordinate verbally and agree on the runway assigned, as well as any 

restrictions such as hold short points of an intersecting runway after 

landing. 

(3) After landing and exiting the runway, the flight crew should coordinate 

verbally and agree on the ATC taxi instructions to the aircraft’s parking 

area, including any instructions to hold short of, or cross any 

intersecting runways. 

(4) At complex intersections, the flight crew should verbally coordinate to 

ensure that the intersection is correctly identified and that the aircraft is 

transitioning through the intersection to the correct taxiway. 

(5) When approaching an intersecting runway, the flight crew should 

verbally coordinate in order to identify the runway. They should also 

verbally review the ATC instructions as to whether they are to hold 

short of or cross the runway. 

(6) Before crossing the hold short line or entering or crossing a runway 

for takeoff or landing, the flight crew should visually scan to the left 

and right, including the full length of the runway and its approach 

paths, and coordinate verbally that the area scanned is or is not 

clear. The pilot flying will callout “cleared to cross (runway number 

or taxiway name)”. The pilot monitoring will then confirm verbally 



that the aircraft is cleared to cross the runway or taxiway. If the pilot 

monitoring does not verbally conform this, the pilot flying shall not 

cross until verbal conformation is received. 

(7) Before entering a runway for takeoff, the flight crew shall verbally 

coordinate to ensure correct identification of the runway and receipt of 

the proper ATC clearance to use. Confirm runway directional 

alignment with the aircraft’s magnetic compass, horizontal situation 

indicator, and/or flight management system. Similar verification should 

be performed during approach to landing. 

(8) When a flight crewmember needs to stop monitoring any ATC 

frequency, the crewmember shall inform the other flight 

crewmember(s) when stopping and resuming the monitoring of an ATC 

frequency. Any instructions or information received or transmitted 

during that flight crewmember’s absence from the ATC frequency 

should be briefed and reviewed upon the crewmember’s return. 

(9) When the pilot not taxiing the aircraft focuses his or her attention on 

instruments in the cockpit, such as entering the data into the aircraft’s 

Flight Management System or Global Positioning System (GPS), and 

subsequently is not able to visually monitor the aircraft’s progress, he 

or she should verbally notify the pilot taxiing the aircraft. Likewise, 

notification should be made when that flight crewmember has 

completed his or her task and is again able to assist in visually 

monitoring the taxi operation.

Brake/Steering Checking Procedures 

When first beginning to taxi, conduct a check of braking effectiveness by: 

Allowing the airplane to begin movement under power; then, 

Reduce the power to idle and depress the top portion of both rudder 

pedals (brake function) sufficiently to bring the airplane to a complete 

stop. 

Verify that the braking effort, braking action, and pedal travel are all 

satisfactory. 

Verify that the airplane steering is satisfactory by: 

Depressing the rudder pedal in the direction of turn desired 

Verify that the airplane responds properly to the rudder pedal input. 

NOTE 

When an Instructor Pilot (IP) is seated in either the left or right 

front seat, the IP shall conduct a separate check of 

braking/steering effectiveness from that seating position to 

ensure that the rudder pedals are functioning properly, 

effectively, and satisfactory. 

Ensure that the throttle levers are set at idle before initiating a 

positive exchange of the flight controls. 



ENGINE PRIMING PROCEDURES 

NOTE 

The engine starting procedures that follow are applicable to 

both engines. 

Cold Engine - Oil temperature 148° F or less (outside green). 

1. STROBE LIGHTS ............................................................................... ON 

2. THROTTLE LEVER .......................................................... 1” FROM IDLE 

3. FUEL PUMP ....................................................................................... ON 

4. MIXTURE CONTROL LEVER .................................................................. 

............................................. FULL RICH 3 to 5 seconds/IDLE CUT-OFF 

5. FUEL PUMP ..................................................................................... OFF 

6. THROTTLE LEVER ......................................................... ½” FROM IDLE 

Continue with ENGINE START FLOW 

NOTE 

Hot weather starting procedures depend upon how soon the 

next engine start is attempted. Within the first 20 to 30 minutes 

after shutdown, the fuel manifold is adequately primed and the 

empty injector nozzle lines will fill before the engine would 

cease to run (no additional priming should be needed). 

Warm Engine - Oil Temperature 149° F or greater (within green). 

1. THROTTLE LEVER .......................................................... 1” FROM IDLE 

2. FUEL PUMP ....................................................................................... ON 

3. MIXTURE CONTROL LEVER .................................................................. 

........................................ FULL RICH 1 to 2 SECONDS/IDLE CUT-OFF 

4. FUEL PUMP ..................................................................................... OFF 


NOTE 

After engine start, advance the Mixture Control 1/3 open, then 

smoothly to the Full Forward (Full Rich) position as power 

develops. 



Flooded Engine 

1. FUEL PUMP ..................................................................................... OFF 

2. MIXTURE CONTROL LEVER ......................................... IDLE CUT-OFF 

3. THROTTLE LEVER ......................................................... MID POSITION 

4. IGNITION SWITCH....................................................................... START 

After engine starts: 

5. THROTTLE LEVER .......................................................................... IDLE 

6. MIXTURE CONTROL LEVER ............................................... FULL RICH 


NOTE 

If the throttle is open much greater than 1/2 inch when the 

engine starts, the engine will surge to a much higher than 

normal RPM. Operating the engine in this manner may cause 

internal engine damage due to a lack of prior circulated oil. 

CAUTION 

Do not overheat the starter motor. Do not operate the starter 

motor for more than 10 seconds. After operating the starter 

motor, let it cool for 20 seconds. After 6 attempts to start the 

engine, allow the starter to cool for 30 minutes. 

If subsequent start attempt is unsuccessful, contact the Fleet 

Maintenance Department. 



LEANING PROCEDURES 

The following leaning procedures, developed for use during ground, climb, 

cruise, descent, and landing operations, are employed to aid in 

preventative maintenance and flight safety operations. 

With respect to the engine operation, utilization and adherence to these 

procedures are important, especially during high power settings and rich 

mixture settings, to prolong the engine life and to ensure flight safety. 

GROUND 

Lean to peak engine RPM: 

- Confirm that the Mixture Control Lever is in the Full Forward (Full- 

Rich) position. 

- Adjust the Throttle Lever to set 1200 RPM. 

- Lean the mixture by slowly moving the Mixture Control Lever aft while 

observing engine RPM slowly increasing. 

- Continue leaning the mixture until the engine RPM begins to 

decrease. 

- Once a decrease in engine RPM is observed, enrichen the mixture by 

slowly moving the Mixture Control Lever forward until peak engine 

RPM is attained. 

- Adjust the Throttle Lever to set 1000 RPM. 

TAKEOFF (High elevation airports only) 

- Lean the mixture for takeoff only when the airplane is operating at, or 

above 5000’ Density Altitude, by slowly moving the Mixture Control 

Lever aft to obtain the best power mixture setting. 

CLIMB (Below 5000’ Density Altitude) 

- Leave the Mixture Control Levers in the Full Forward (Full Rich) 

position. 

NOTE 

The mixture may be leaned at lower altitudes if necessary to 

obtain smooth engine operation. 



CRUISE (Best Economy Mixture) 

- Lean the mixture by slowly moving the Mixture Control Lever aft until 

a decrease in engine RPM or engine roughness is observed. 

- Enrichen the mixture by slowly moving the Mixture Control Lever 

forward until peak engine RPM and smooth running of the engine are 

attained. At the same time, the Exhaust Gas Temperature (EGT) 

should reach maximum (Peak) 

CAUTION 

CAUTION 

The best economy mixture setting may only be used up to a 

power setting of 75%. 

CRUISE (Best Power Mixture) 

- Lean the mixture by slowly moving the Mixture Control Lever aft until 

a decrease in engine RPM or engine roughness is observed. 

- Enrichen the mixture by slowly moving the Mixture Control Lever 

forward until the Exhaust Gas Temperature (EGT) is approximately 

100° F lower (Rich of Peak EGT) 

CAUTION 

CAUTION 

The mixture should be enrichened slightly before selecting a 

higher power setting. The Mixture Control Lever should always 

be moved slowly. 

MANEUVERS (Local) 

Ground Reference Maneuvers: 

- Slowly move both Mixture Controls to the Full Forward (Full-Rich) 

position. 

- Depress the Fuel Pump switches to the ON position (Below 1000’ 

MSL). 

Other Maneuvers: 

- Leave both Mixture Control Levers in the established leaned position. 

- Ensure that both Fuel Pumps switches are in the OFF position. 



DESCENT 

- Slowly move the Mixture Control Levers forward to enrichen the 

mixture during the descent. 

LANDING 

When operating VFR: 

- Verify that both Mixture Control Levers are in the Full Forward (Full- 


- Depress both Fuel Pumps switches to the ON position when 

descending through 1,000’ AGL. 

When operating IFR: 

- Verify that both Mixture Control Levers are in the Full Forward (Full- 

Rich) position at 500’ above MDA or DA as applicable. 



All VFR airplanes entering the traffic pattern: 

- Verify that both Mixture Controls are in the Full Forward (Full- Rich) 

position. 








Section 1: 

PRE-FLIGHT 

PROCEDURES 






INITIAL AIRCRAFT ACCEPTANCE 

CLIPBOARD CHECK 

Verify that the aircraft Tachometer agrees with what is entered on the 

Aircraft Condition board. 

Review past discrepancies and deferred items to ensure that no open 

discrepancies exist. 

Verify that all aircraft and equipment inspections are current including: 

100-hour inspection 

Annual Inspection 

24-month Transponder Test and Inspection 

24-month Altimeter, Pitot-Static System, and automatic pressure 

altitude reporting system (Mode S) Test and Inspection 

12-month ELT unit Inspection 

ELT Battery 

VOR Accuracy Check (if applicable) 

Survival Kit 

Check oil and fuel levels first to avoid any delays on departure. 

Clean the interior and exterior sides of the canopy with approved 

cleaning solution and towels. A clean canopy increases visibility and 

collision avoidance. Ensure that there are no cracks in the canopy. Do 

not place any item(s) (i.e. headsets, clipboard, etc.) on top of the glare 

shield panel, as this can scratch the canopy.

NOTE 

When using the step on the DA42 L360, grasp the handhold 

located behind the rear cabin door to support your body weight. 

Stepping onto the step without using the handhold may 

damage the step, weakening its welded construction, and 

creating an unsafe condition. 

1. GUST LOCKS (if installed) REMOVE 

REMOVE the GUST LOCKS (if installed) from all flight control surfaces. 

Stow and secure the gust locks in the aft baggage compartment. 

CAUTION 

The ailerons or rudder will be damaged if moved with the gust 

locks installed. 

2. PITOT/STATIC MAST COVER REMOVE 

REMOVE the PITOT/STATIC MAST COVER from the Pitot/Static Mast 

(located on the underside of the left wing). 

3. ENGINE OIL QUANTITY CHECK 

CHECK the ENGINE OIL QUANTITY on Left and Right engines. Oil 

quantity should be a minimum of 7 quarts for local flight operations. Ensure 

that the dipsticks are secured. 



If the level is below seven (7) quarts, obtain Exxon Elite 20W-50 

oil from the ramp fuel truck or applicable FBO. Use Aeroshell 

100 (SAE 50) or equivalent, only if Exxon Elite 20W-50 is 

unavailable. 

4. FUEL QUANTITY (MAIN/AUX) CHECK 

CHECK the FUEL QUANTITY in the MAIN and the AUX (Auxiliary) tanks. 

Refer to the ERAU Flight Operations Manual for fuel requirements. Ensure 

that the fuel cap is secured in place with the fuel cap lever folding down 

and toward the trailing edge of the wing. 

NOTE 

The fuel quantity indicators shall not substitute for visually 

checking fuel quantity. 

As standard configuration for all ERAU DA42 L360 aircraft, both 

auxiliary fuel tanks will be fully filled for each flight. 

CALL FOR SERVICE IF NEEDED 

If insufficient fuel or oil is noted, contact ERAU Flight Data 

(Eagle Data) on 122.825 MHz to request aircraft servicing (Fuel 

Truck). 

5. FUEL SUMPS (6) DRAIN 

Using the fuel sample cup (GATS Jar), DRAIN a small quantity of fuel from 

the six (6) flush-type FUEL SUMPS located under each wing, to the side of 

each cowling (gascolator), and auxiliary tank (behind each engine nacelle). 

Check for water, sediment, and verify that the proper grade of fuel (100LL, 

Blue in color) is present. Water in the sample will be indicated by a clear 

amount of liquid at the bottom of the sampler cup (due to the greater 

density of water than fuel). Dispose of contaminated fuel in the fuel 

receptacles located on the east side of the ERAU ramp. Remove any 

residual water from inside of sampler cup and continue to take fuel samples 

until water is no longer present in any fuel sample. 

NOTE 

DO NOT DUMP FUEL ON THE RAMP. 

6. CONTROL LOCK REMOVE 

REMOVE the CONTROL LOCK and stow it in the aft baggage 

compartment. 



7. DOCUMENTS CHECK 

CHECK that the Airworthiness Certificate and Aircraft Registration are on 

board the airplane. If the airplane has a temporary registration (Pink color), 

check that the temporary registration’s date is within 90 days of its 

issuance. Verify that the DOCUMENTS have the correct registration 

number (“N” number) for the airplane. Ensure that the Airworthiness 

Certificate is displayed and clearly visible. 

8. AFM AVAILABLE 

Ensure that the AFM (Airplane Flight Manual) for that airplane is 

AVAILABLE, including the weight and balance documentation (per 14 CFR 

Part 91.9). 

9. G1000 CRG AVAILABLE 

Ensure the G1000 (Garmin 1000) CRG (Cockpit Reference Guide) is 

AVAILABLE and updated to the latest version of the G1000 system

Depress the Fuel Pump switches to the ON position and place both FUEL 

SELECTORS (LH/RH) in the CROSSFEED position for 30 seconds. 

Monitor the engines for any abnormal indications. 

WARNING 

When the Fuel Selector is moved from ON to CROSSFEED, or 

from CROSSFEED to ON, the corresponding Fuel Pump must 

be turned on. 

Other than for testing of the Crossfeed operation, the operation 

of both engines with both fuel selectors in the CROSSFEED 

position is prohibited. 

2. AVIONICS MASTER SWITCH ON 

Depress the AVIONICS MASTER SWITCH to the ON position to power the 

AVIONICS bus. 

3. PITOT HEAT TEST 

Test the proper function of the Pitot Heat system by turning the PITOT 

HEAT switch to ON and verifying a proper indication on the PFD. 

NOTE 

The stall warning switch gets slightly warmer on ground only 

and STALL HT FAIL is indicated on the PFD. 



1. PFD/MFD SET 

On the PFD, verify that the clock is operating and indicating the current 

time, and that the adjustable flight instruments are SET to current and 

available information (as per 14 CFR Part 91.205). All instrument 

indications on the PFD should be visible in approximately 1 minute. 

IFR CONSIDERATIONS 

For IFR flight, the primary and standby flight instruments must be 

checked and within acceptable limits before taxi. The gyroscopic 

instruments, magnetic compass, turn rate indicator, and slip/skid 

indicator should be checked while turning in both directions during 

taxi after leaving the ramp. 

Primary Instruments 

- The Attitude Indicator should indicate the aircraft’s current pitch 

and bank attitude. No Red-X’s should be visible. 

- The Airspeed Indicator should indicate zero. No Red-X’s should 

be visible. 

- The Horizontal Situation Indicator should be indicating known 

headings with no Red-X over the heading reference. 

- The Altimeter should be within ±75 feet of known elevation when 

set to the local altimeter setting (elevations are shown on airport 

diagrams). No Red-X’s should be visible. 

- The Vertical Speed Indicator (VSI) should indicate zero, or if an 

error is noted, note the error and use as the zero reference point. 

No Red-X’s should be visible. 

- Use the altitude bug to set the departure clearance altitude in the 

Altitude Reference Box. The bug acts as a visual reference to 

indicate the desired altitude is approaching. 

AVIONICS: 

- Communication Radios: Ensure both Comm radios are operating 

(transmitting and receiving) properly by alternating their uses with 

ATC. For example, tune in the ground frequency in the opposite 

Comm radio from the one used to ramp out and receive ATIS. 

This will ensure that both Comm radios are operating properly. 

Set the radios for departure. 

- NAV 1: Depress the NAV 1 speaker switch (after turning the 

volume down) and ID the appropriate frequency by using the 

ID/Volume knob. Next, check the needle swing and flag flip on the 

CDI. Finally, set the departure radial. 



- NAV 2: Follow the same procedure as NAV 1, but include the next 

radial in the departure as appropriate. 

- Transponder: Ensure that the assigned code is set in the 

transponder (the test to check the operation of the unit for proper 

functioning is automatic). 

NOTE 

At airports where a VOT is available, the NAV radios may be 

checked using the VOT. If unable to identify the NAVs on the 

ground, try again in another position such as the run-up area, 

or, if necessary, wait until airborne, although, this increases 

workload in the air and should be planned for accordingly. 

Recheck that each COM/NAV frequencies and HSI/CDI is set for 

departure. Just before takeoff, review the VFR/IFR departure by 

mentally flying it, including headings, altitudes and navigation. 

On the MFD, verify that the map options and range are SET as desired 

(topography, terrain, traffic, etc). 

NOTE 

An altitude alert is annunciated 1000 feet prior to arrival at the 

selected altitude. A further alert is annunciated if the airplane 

deviates from the selected altitude by +/- 200 feet. 

5. STANDBY INSTRUMENTS CHECKED/SET 

Verify that the STANDBY INSTRUMENTS are CHECKED and SET: 

- The Standby Airspeed Indicator should indicate zero. 

- The Standby Attitude Indicator should be set (caged) and have the 

miniature aircraft adjusted to level flight with the horizon and 

indicate no more than 5° of precession in pitch and bank during 

turns. No flags should be visually present. 

- The inclinometer should be centered and displacing towards the 

opposite direction of the turn during taxi. 

- The Standby Altimeter should be within ±75 feet of known 

elevation when set to the local altimeter setting (elevations are 

shown on airport diagrams). 

- The Magnetic Compass housing should contain full fluid, swing 

freely, and indicate known headings. 



- The Compass Deviation Card must be in place and readable. 

6. AUTOPILOT / ELECTRIC TRIM TEST 

CAUTION 

The entire preflight test procedure must be successfully 

completed prior to each flight. Use of the autopilot or manual 

electrical trim system is prohibited prior to completion of these 

tests. 

To ensure proper functioning, TEST the AUTOPILOT as follows: 

When the AVIONICS MASTER SWITCH is turned On, power will be 

supplied to the computer and the AUTOPILOT will begin a Self-TEST 

[the TEST is COMPLETE by all display segments being illuminated 

(Display TEST) and the disconnect tone sounding]. 

WARNING 

If the AP TRIM FAIL annunciator stays on, the Auto-Trim 

did not pass the pre-flight test. The autopilot circuit 

breaker must be pulled. Manual electric trim cannot be 

used. 

6. AUTOPILOT / ELECTRIC TRIM (continued) TEST 

a. TEST the manual ELECTRIC TRIM (press the AP DISC button 

down and hold while commanding trim. The manual Electric Trim 

should not operate either nose up or nose down) 

b. Engage the autopilot by pressing the AP button. 

c. Move the Flight Controls fore, aft, left, and right to verify that the 

autopilot clutches can be overpowered. 

d. Press the AP DISC switch and verify that the autopilot 

disconnects. 

e. Manually set the trim to the takeoff position. 

f. Press the AP DISC switch. 

g. Set the local altimeter setting on the autopilot. 



h. Rotate the ALTITUDE SELECT knob until the desired altitude is 

displayed. 

TEST the manual ELECTRIC TRIM as follows: 

a. Depress the split pilot yoke-mounted Electric Trim switches 

simultaneously forward, then aft, verifying each time that the 

Stabilator trim wheel and its indicator moves in the appropriate 

direction. 

b. While moving the Stabilator trim in either direction, verify that the 

control yoke cut-off switch disables the Electric Trim function. 

c. While depressing the Electric Trim interrupt switch, verify that the 

Stabilator trim wheel stops. Verify that the Stabilator trim wheel 

moves in the appropriate direction when the trim interrupt switch is 

released. 

d. Depress the Electric Trim On/Off switch to the OFF position and 

depress the split pilot yoke-mounted Electric Trim switches 

simultaneously forward and aft, each time verifying that the 

Stabilator trim wheel and its indicator does not move. This test 

ensures that the Electric Trim will disengage in the event of an 

Electric Trim malfunction. 

8. FUEL SELECTORS (LH/RH) ON 

Depress the fuel pump switches to the ON position and place both FUEL 

SELECTORS (LH/RH) in the ON position. 

9. PARKING BRAKE RELEASE 

Move the PARKING BRAKE lever fully up to the RELEASE position. 

NOTE 

During taxi, check for proper operation of the brakes and 

steering. Monitor the G1000 for correct pitch attitude and 

directional indications. 

CAUTION 

When taxiing on a poor surface select the lowest possible RPM 

to avoid damage to the propeller from stones or similar items. 



CAUTION 

Following extended operation on the ground, or at higher 

ambient temperatures, rough running of the engine may occur, 

shown by the following indications: 

- Transient changes in idle RPM and Fuel Flow 

- Slow reaction of the engine to operation of throttle levers 

- Engine will not run with the throttle levers in the idle 

position. 

Remedy for rough running engine: 

1. Depress the Fuel Pump switch to the ON position. 

2. Adjust the THROTTLE LEVER to set the engine at speed of 1800 to 

2000 RPM for 1 to 2 minutes, or until the engine settles. Oil and 

cylinder head temperatures must stay within limits. 

3. Move the THROTTLE LEVERS back to IDLE to confirm smooth 

running. 

4. Adjust the THROTTLE LEVERS to set 1200 RPM and adjust the 

MIXTURE CONTROL LEVER to achieve maximum RPM attainable 

(lean the Mixture). 

5. Depress the FUEL PUMPS to the OFF position. 

6. During BEFORE TAKEOFF RUN-UP CHECK, set the MIXTURE 

CONTROL LEVER for takeoff and advance the THROTTLE LEVER 

to MAX POWER for 10 seconds. Ensure smooth running of the 

engine and proper engine indications. 

NOTE 

Step 6 may be performed on the runway before takeoff with 

prior coordination with ATC. 

10. BEFORE TAXI CHECKLIST COMPLETE 

Upon completion of the BEFORE TAXI CHECKLIST, verify that all items

4. ENGINE INDICATIONS CHECK 

Verify that the ENGINES INDICATIONS are showing Oil Temperature 

above 100° F, and Cylinder Head Temperature (CHT) above 150° F, before 

advancing the throttle levers for the RUN-UP CHECK. 

5. MIXTURE CONTROL LEVERS 

FULL FORWARD (Below 5000 ft.) 

Below 5,000 ft., move the MIXTURE CONTROL LEVERS to the FULL 

FORWARD (Full Rich) position. 

NOTE 

At a density altitude of 5000 ft. or higher, or at high ambient 

temperatures, a fully rich mixture can cause a rough running 

engine and/or a loss of performance. The mixture should be set 

for smooth running of the engine. 



position. 

7. THROTTLE LEVERS 2200 RPM 

After checking that the area behind the aircraft is clear, smoothly move the 

THROTTLE LEVERS forward to set 2200 RPM. 

8. MAGNETOS (175/50 RPM) CHECK 

CHECK the MAGNETOS by rotating the key in the ignition switch to the R 

(Right) magneto position and noting engine RPM. Rotate the key to return 

to the BOTH position (to ensure clearing the spark plugs on the other 

magneto). Then, rotate the key to the L (Left) magneto position and note 

the engine RPM. Then, check the right engine magnetos in the same 

manner. RPM drop for either magneto should not exceed 175 RPM, nor 

should the difference in RPM drop between the magnetos exceed 50 RPM. 

CAUTION 

The lack of an RPM drop suggests a faulty grounding or 

incorrect ignition timing. In case of doubt the magneto check 

can be repeated with a leaner mixture, in order to confirm a 

problem. Even when running on only one magneto the engine 

should not run unduly roughly. 



NOTE 

If the RPM drop exceeds 175 RPM, slowly lean the mixture until 

the RPM peaks. Then, retard the throttle to 2200 RPM for the 

magneto check and repeat the check. If the drop-off does not 

exceed 175 RPM and the difference between the magnetos does 

not exceed 50 RPM, and the engine is running smoothly, the 

ignition system is operating properly. Return the Mixture 

Control Levers to the Full Forward (Full Rich) position. 

NOTE 

If a fouled spark plug is suspected: 1) Smoothly advance 

throttles to full forward, 2) Lean the mixtures to peak EGT for 45 

seconds, 3) Monitor CHT and Oil Temperatures, 4) Enrichen 

mixtures to FULL RICH, 5) Smoothly reduce throttles to 2200 

RPM, 6) Proceed with magneto check. 

9. PROPELLER RPM CYCLE 

To check propeller operation, CYCLE the PROPELLER by moving the 

PROPELLER RPM LEVER aft to the Feather Gate-Stop until a drop of

3. REAR DOOR ........................................................ CLOSED/LATCHED 



6. FLAPS ............................................................................................... UP 


8. PFD/MFD ........................................................................................ SET 

9. TRAFFIC ................................................................................... CHECK 

10. BEFORE TAKEOFF CHECKLIST ...................................... COMPLETE 

1. PRE-TAKEOFF BRIEFING COMPLETE 

COMPLETE a verbal PRE-TAKEOFF BRIEFING that covers how normal, 

abnormal and emergency situations would be handled during takeoff (see 

the Sample Pre-Takeoff Briefing below). 

Sample Pre-Takeoff Briefing 

“This will be a VFR/IFR Departure using Runway 7 Left at November 

with; 4,500 feet available. We need 1,300 feet for takeoff and an 

accelerate stop distance of 3,000 feet. No significant obstacles or 

wake turbulence are expected for departure. At takeoff, the wind will 

be from our right at 7 knots, so ailerons will be positioned to the 

right. V R is 78 KIAS; initial climb speed is 90 KIAS. If there is an 

engine fire, failure, or significant system malfunction: 

Before rotation, I will close both throttle levers, maintain directional 

control with rudder to remain on the runway, and brake as required. 

After rotation with runway available for landing, I will smoothly 

reduce both throttle levers, re-check the landing gear is down, and land 

on the remaining runway. 

After rotation with no runway available or gear in transit, I will 

maintain directional control, pitch for V YSE (90 KIAS) and execute oneengine 

inoperative procedures. I will call the tower, declare an 

emergency and return to 7L for a single engine landing. Our calculated 

single engine rate of climb is 200 FPM, but in case of inadequate climb 



performance, we will go straight ahead for a controlled off-airport 

landing.” 

2. FRONT CANOPY CLOSED/LATCHED 

CLOSE (do not slam) and latch the FRONT CANOPY. Ensure that the 

CANOPY is properly LATCHED and that there is no DOOR OPEN Warning 

displayed on the PFD. 

3. REAR DOOR CLOSED/LATCHED 

Verify that the REAR DOOR is CLOSED and LATCHED. 


SET the ELEVATOR TRIM for takeoff. Ensure that the AUTOPILOT is not 

engaged for takeoff.

the FLAPS visually. 


CHECK that all CIRCUIT BREAKERS are in by running your hand across 

the circuit breaker panel. If a circuit breaker is out, call Fleet Maintenance. 

Do not push the circuit breaker in. 


Check the PFD/MFD to ensure that the flight instruments and AVIONICS 

are SET for takeoff. For the flight instruments, verify the altimeter setting 

and that the HSI is SET for proper indications (magenta or green needles 

as appropriate). For the AVIONICS, verify that all frequencies have been 

tuned for departure, and that the transponder code is SET, and if 

applicable, that the flight plan is entered and activated. If staying in the 

local area for instrument approaches, ensure that the approach is loaded 

and ready to be activated. 

9. TRAFFIC CHECK 

Turn the airplane towards the approach end of the runway and visually 

CHECK that the Final is clear of TRAFFIC.

Upon completion of the BEFORE TAKEOFF CHECKLIST, verify that all 


NOTE 

Single-Pilot Resource Management (SPRM) refers to the 

effective use of ALL available resources: human resources, 

hardware, and information. Pilot resource management is not a 

single task; it is a set of skill competencies that must be evident 

as applied to single-pilot operation. Workload management and 

situational awareness are to a certain degree observable 

behaviors that show these competencies. 

Most of the planning and preparation should be done before 

takeoff so that the pilot prepares during low workload 

situations for high workload situations.

Section 3: 

EMERGENCY 

PROCEDURES 



INTRODUCTION 

Successful handling of emergency situations is largely dependent on the 

judgment and skill of the flight crew. All emergency conditions should be 

handled with planning and organization. Although it is not possible to write 

specific procedures to cover every facet of every emergency or irregularity 

a pilot may confront, it is possible to establish certain operating guidelines. 

The overriding matter of importance is very basic: someone must fly the 

airplane. In addition to executing the required procedure(s), the pilot must 

still devote primary attention to the control and navigation of the airplane 

with regard to terrain, weather, air traffic control, and airplane configuration. 

There are some situations which always require a landing at the nearest 

suitable airport. These situations include, but are not limited to, cabin 

smoke or fire that persists, loss of equipment cooling, and electrical faults 

that result in only leaving a single critical system remaining. In any event, it 

is the responsibility of the pilot in command to assess the situation and 

execute sound judgment to determine the safest course of action to be 

taken. It is stressed that for persistent smoke, or a fire that cannot be 

positively confirmed to be completely extinguished, the earliest possible 

descent, landing, and passenger evacuation should be accomplished. 

Cycling or resetting tripped circuit breakers shall not be done 

indiscriminately. Cycling or resetting circuit breakers on the ground is 

acceptable, except for those prohibited in any procedure. Before cycling or 

resetting a circuit breaker in flight, the pilot in command shall consider 

available resources such as the AIRPLANE FLIGHT MANUAL (AFM), the 

ERAU Fleet Maintenance Department, and pilot experience to ensure that 

no restriction(s) exist. 

A tripped circuit breaker may be reset one time after a 90-second cooling 

period. Consider the relative importance of the inoperative component to 

the remainder of the flight, as well as other indications (i.e., other tripped 

circuit breakers, etc.) prior to resetting the associated circuit breaker. 



Discrepancy Reporting/Flight Log Entries 

Reporting of a system and other airplane discrepancies to the ERAU Fleet 

Maintenance Department is of the utmost importance. Prompt notification 

not only allows Fleet Maintenance to respond quickly, but to pre-plan for 

down line maintenance. In addition, reporting certain mechanical 

discrepancies such as: engine failures, fire warnings, and fire extinguisher 

discharges are required by regulation. 

Emergency Procedures 

Initially, flying the airplane and confirming an emergency are most 

important steps in dealing with any emergency. Emergency procedures 

may include immediate action items that are of such critical nature that they 

must be accomplished from memory. Memory steps are enclosed in a 

Dashed Box. Memory steps are to be called out and accomplished prior to 

reading the checklist. When accomplishing the checklist, the pilot reads 

the checklist aloud, taking note of all instructions. Conditions permitting, 

the Pilot Flying (PF) maintains an awareness of checklist progress and 

announces when the emergency procedure is complete. 

Communications 

Proper communication during normal, emergency, and abnormal situation 

is essential to safe and effective mission management. Such situations 

include, but are not limited to, airplane system irregularities and 

emergencies, medical emergencies, and diversions. In such 

circumstances, the pilot should communicate as appropriate with: 

- ATC: Declaring emergency and communicating intentions. 

- ERAU Dispatch: Coordinating emergency support and/or diversions. 

- ERAU Fleet Maintenance Department: Support for resolving and 

handling airplane system abnormalities. 

- FSS: Obtaining weather updates and coordinating emergency 

support and/or diversions. 

Advising control and resource groups of these situations as well as pilot 

intentions is paramount in utilizing all available resources to arrive at an 

informed plan of action. 



ENGINE FAILURE DURING TAKEOFF FLOW 

(DURING GROUND ROLL) 

OBJECTIVE: 

To safely stop the airplane if an engine fails during the takeoff 

roll when the speed is below 78 KIAS, or, if airborne at a speed 

below 78 KIAS when the landing gear is down (extended). 



ENGINE FAILURE DURING TAKEOFF CHECKLIST 

(DURING GROUND ROLL) 

If sufficient runway remains for a complete stop: 

1. THROTTLE LEVERS ............................................ IDLE IMMEDIATELY 

2. DIRECTIONAL CONTROL .................................................... MAINTAIN 

3. BRAKE .......................................................................... AS REQUIRED 

If insufficient runway remains for a complete stop: 

4. FUEL SELECTORS ....................................................................... OFF 




8. ENGINE FAILURE DURING TAKEOFF CHECKLIST (DURING 

GROUND ROLL) ................................................................ COMPLETE 

1. THROTTLE LEVERS IDLE IMMEDIATELY 

Upon the first indication of an engine failure during the takeoff roll, 

IMMEDIATELY move both THROTTLE LEVERS to IDLE while maintaining 

directional control. 

When appropriate, advise ATC, or announce on the CTAF, that the takeoff 

has been aborted. 

2. DIRECTIONAL CONTROL MAINTAIN 

MAINTAIN DIRECTIONAL CONTROL of the aircraft, avoiding obstacles. 

NOTE 

Items 1 and 2 must be accomplished simultaneously. An 

aborted takeoff is a very critical maneuver requiring timely 

decision-making and reaction. In addition, for every takeoff, 

calculating an accelerate/stop distance is important for takeoff 

planning and aeronautical decision-making. 

3. BRAKE AS REQUIRED 

When on the runway, BRAKE, AS REQUIRED, to stop straight ahead on 

the remaining runway, taking care not to lock the wheels. If able, exit the 

airplane onto a taxiway. 



NOTE 

Avoid locking the wheels, which will cause skidding, resulting 

in an increase in the stopping distance, and may cause one or 

both main gear tires to blow. 


4. FUEL SELECTORS OFF 

Place both FUEL SELECTORS in the OFF position to stop the flow of fuel 

to the engines and reduce the possibility of fire and injury to the crew 

members. 




Turn the IGNITION SWITCHES to the OFF position to ground the 

magnetos, disabling the engine ignition system.

necessary to avoid any obstacles. 

If airborne, land the airplane. Reduce power as necessary to maintain 

sufficient airspeed for directional control, adjusting the pitch attitude to 

avoid a high sink rate. 

Advise ATC, or announce on the CTAF that the takeoff has been aborted. 



NOTE 

Items 1 and 2 must be accomplished simultaneously. An 

aborted takeoff is a very critical maneuver requiring timely 

decision-making and reaction. In addition, for every takeoff, 

calculating an accelerate/stop distance is important for takeoff 

planning and aeronautical decision-making. 

3. LAND STRAIGHT AHEAD 

LAND STRAIGHT AHEAD, making small turns only to avoid obstructions. 

4. BRAKE AS REQUIRED 

When on the runway, BRAKE, AS REQUIRED, to stop straight ahead on

necessary to prepare for a NORMAL APPROACH and landing. 

WARNING 

Under some conditions of loading and density altitude, a goaround 

may be impossible. A one engine inoperative goaround 

should be avoided if at all possible. In any event, the 

sudden application of power during a one engine inoperative 

operation will make control of the airplane more difficult. 

When landing is assured: 


Place the GEAR SELECTOR in the DOWN position. Visually check for the 

3 GREEN indicator lights. Visually check the external engine nacelle mirror 

to confirm that the nose gear is extended. 

11. FLAPS AS REQUIRED 

When landing is assured, below V FE (111 KIAS) extend the FLAPS to APP 

or LDG position, AS REQUIRED. 

NOTE 

One-Engine Inoperative approaches for landing with flap 

settings of more than Flaps up are not recommended unless 

the safe landing is assured. Higher flap settings increase the 

loss of altitude during the transition to a One-Engine 

Inoperative Go-around / Rejected (Balked) Landing. 



NOTE 

No flap landing with power will have reduced elevator travel due 

to limiter being engaged above 14.5 inches MP.

climb performance. 


After a positive climb is achieved, place the GEAR SELECTOR in the UP 

position to retract the landing gear. When appropriate, call out, “Gear Up, 

NO LIGHTS” to indicate that the landing gear has completed its retraction. 

NOTE 

Waiting until a positive climb is achieved prior to retracting the 

landing gear is important because, with the possibility that the 

airplane could contact the ground during the go-around, the 

landing gear will help to absorb the impact. 

6. AIRSPEED 90 KIAS /AS REQUIRED 

Adjust pitch attitude to maintain an AIRSPEED of 90 KIAS, or AS 

REQUIRED, until clearing obstacles. Bank up to 5° into the operating 

engine to help establish best climb performance 

7. ELEVATOR TRIM /RUDDER TRIM AS REQUIRED

Section 4: 

ABNORMAL 

PROCEDURES 



INTRODUCTION 

Successful handling of abnormal situations is largely dependent on the 

judgment and skill of the crew. All abnormal conditions should be handled 

with planning and organization. Although it is not possible to write specific 

procedures to cover every facet of every abnormal situation or irregularity a 

pilot may confront, it is possible to establish certain operating guidelines. 

The overriding matter of importance is very basic: someone must fly the 

airplane. In addition to executing the required procedure(s), the pilot must 

still devote primary attention to the control and navigation of the airplane 

with regard to terrain, weather, air traffic control, and airplane configuration. 

Abnormal Procedures 

An abnormal procedure is a procedure not classified by the aircraft 

manufacturer as a normal or emergency procedure. The abnormal 

procedures that follow are the only abnormal procedures provided by the 

aircraft manufacturer and may not cover every abnormal situation that may 

be encountered during flight. The Abnormal procedures do not include 

immediate action or memory items because the checklist items are not 

time-critical in nature. 

If an abnormal situation arises, the number one priority is to maintain 

control of the airplane, and then confirm the situation and follow the 

appropriate procedures. 

When operating in the pseudo-crew environment, the pilot not flying (PNF) 

shall perform the checklist and announce its completion. The Pilot flying 

(PF) shall maintain an awareness of the checklist progress. 



AIR STARTING/UNFEATHERING CHECKLIST 

Restarting the engine is possible at all airspeeds above a safe 

flying airspeed up to V NE (194 KIAS) and up to the maximum 

demonstrated operating altitude.

NOTE 

When propeller unfeathering occurs, it may be necessary to 

retard the propeller control to prevent the propeller from 

overspeeding. 

In the event of a total electrical power failure, the propeller 

accumulator will not unfeather the propeller. In this case, 

increase airspeed safely until propeller windmills. 

After the propeller windmills:

Move the PROPELLER RPM LEVER for the Inoperative Engine to the 

FULL FORWARD position to start the propeller windmilling. 

In the event of a total electrical power failure, the propeller 

accumulator will not unfeather the propeller. In this case, 

increase airspeed safely until propeller windmills. 

After the propeller windmills: 

7. MIXTURE CONTROL LEVER FULL FORWARD 

Once the propeller starts windmilling, slowly move the MIXTURE 

CONTROL LEVER to the FULL FORWARD position. 

8. IGNITION SWITCH BOTH 

Place the IGNITION SWITCH for the engine started to the BOTH position. 



9. ALTERNATOR SWITCH ON
