T-<strong>39</strong> FLIGHT PREPARATION STUDENT GUIDE<br />
RADALT set to 400 feet. All items must be properly set prior to take<strong>of</strong>f. This is to include<br />
altitude alerter set to the first level <strong>of</strong>f altitude, CDI set to the first radial, and heading bug set to<br />
the first heading after runway heading.<br />
b. Take<strong>of</strong>f<br />
The Standard Departure Procedures used by jet aircraft at NAS Pensacola are radar<br />
vectors. Complete the first four items <strong>of</strong> the Lineup Checklist prior to calling for take<strong>of</strong>f. When<br />
cleared for position and hold, or take<strong>of</strong>f, clear the “groove” (final) and clear the runup area for<br />
FOD, and the runway for other aircraft. Upon receiving take<strong>of</strong>f clearance, complete the last two<br />
items <strong>of</strong> the Lineup Checklist.<br />
(1) Note the take<strong>of</strong>f time.<br />
(2) Call “Off the peg”<br />
(3) Call “60 kts”<br />
(4) Call V1 in knots, i.e. “123”.<br />
14. DEPARTURE<br />
a. After noting a positive rate <strong>of</strong> climb<br />
(1) Initiate the After Take<strong>of</strong>f checklist.<br />
(2) When switched by tower - call Departure.<br />
(3) Above 1500 feet AGL, complete the After Take<strong>of</strong>f checklist.<br />
b. Navigate the departure<br />
(1) Call Departure (if not already accomplished).<br />
(2) Monitor engine instruments (EPR, Oil, EGT, RPM, etc) to ensure the engine is<br />
within operating limits.<br />
(3) Initiate the climb checklist (passing 10,000 feet or final level <strong>of</strong>f, whichever<br />
occurs first).<br />
(4) Continue climb checklist passing transition altitude (18,000 feet).<br />
(5) One thousand feet prior to final level <strong>of</strong>f, check outside air temperature (OAT),<br />
give a cruise EPR, and an Indicated Mach Number (Cruise Mach).<br />
The standards for departure include arcing to a tolerance <strong>of</strong> +1 NM and course control to a<br />
tolerance <strong>of</strong> +2 NM and 3 radials. On departure, 90° turns are led by 1% <strong>of</strong> Ground Speed, True<br />
<strong>Air</strong>speed, or Indicated <strong>Air</strong>speed, using that order <strong>of</strong> precedence. Indicated Mach Number (IMN)<br />
is an indication <strong>of</strong> TAS; e.g. 0.5 IMN = 300 KTAS, 0.6 IMN = 360 KTAS, etc. If IAS is 250<br />
KTS and IMN is 0.5, lead the turn by 3 DME. TAS may also be determined by adding 5 KTS<br />
for each 1000’ <strong>of</strong> altitude to the aircraft’s IAS.<br />
EXAMPLE: What is my lead turn to arc on the departure if….<br />
Altitude = 10,000 feet MSL<br />
IAS = 250 KTS<br />
