Flight Instructors Training Procedures _revised AIC_x

Based on a power off, clean configuration
stall from level flight, recovery with power.
SAFETY
HASELL Checks:-
• HEIGHT
Must be able to enter and recover onto an
even keel by 2000’ AGL.
• AIRFRAME
Flaps Retracted (Piper 140/180)
• SECURITY
Loose articles secured, seatbelts tight,
Seats locked in position.
• ENGINE
T’ and P’s; Fuel pump on, select fullest
tank.
• LOCALITY
Not in controlled airspace
Not over built-up area.
Not over gathering of people
Not over mountains
Not over large expanse of water
Not over Airfield
Must be in GFA
• LOOKOUT
Other A/C
Position of sun.
Position of wind.
Position of GFA
• LANDING FIELD
Must identify a suitable field for a forced
landing within easy gliding distance.
• LOOKOUT TURN
360° change of direction or 180°.
ENTRY
• Carburetor heat on.
• Reduce power to idle.
• Maintain level fight by gradually raising the
nose to maintain the same value of lift as
speed decreases until the critical angle of
attack is reached.
• Ailerons neutral throughout.
• Use rudder to maintain wings level.
SYMPTOMS
• High nose attitude
• Low airspeed
• Low noise level
• Sloppy Controls
• Stall warning
• Buffet
CHARACTERISTICS
• Nose Down Pitching moment
• Loss of altitude
IMPORTANT
The following stalls are to be demonstrated and
then flown by the student.
• Stall in approach configuration 1700rpm,
2 notches flap.
• Stall during a steep turn at Vso +10.
• Stall from a mishandled climbing turn to the
right (power 2100 rpm, 15°AOB, speed
85mph – progressively increase aileron into
the turn, hold off bank with opposing rudder
and progressively raise the nose until the
stall and the outside wing drops)
• Stall power off, clean configuration and
recover to level flight with full power as soon
as the stall warning alarm is activated.
• Discuss attitude differences and recovery
techniques for each, noting the height
loss in each.
• Emphasis to be placed on achieving
minimum height loss with each recovery
without compromising safety and
smoothness of control inputs.
FLIGHT EXERCISE BRIEFING
EXERCISE 11
SPINNING AND SPIN AVOIDANCE
*),
• Lower the nose by moving the control
column briskly forward to the neutral position.
• Maintain ailerons neutral.
• Use rudder to correct any wing drop.
• As airspeed increases to V ref (1.3 x stall
speed) raise the nose just above the horizon
and …
Simultaneously apply full power.
Climb back to entry altitude.
Carry out after take-off checks.
Carry out HELL checks.
Note the height loss after recovery.
COMMON FAULTS
• Students preconceived fear of stalling.
• Tenseness on controls.
• Over controlling the nose up attitude entering
the stall.
• Using aileron to pick up wing drop.
• Applying abrupt and steep nose down
attitude in recovery
and
applying power with the nose down resulting
in an excessive and unnecessary height
loss.
• Do not rush the checks.
• Carry out after take-off checks.
• Always climb back to entry altitude and carry
out “HELL” checks and vital actions.
DEFINITION: A spin is the condition of flight where the aircraft is in autorotation which causes yawing, rolling and pitching
moments resulting in the aircraft following a spiral path at a steady rate of descent.
AIM: To provide the student with the knowledge to recognise the conditions leading up to a spin and the correct
application of controls to recover from the spin.
This improves the students confidence and co-ordination knowing that he/she can recover from the spin
which is the worst aerodynamic situation resulting from mishandling the controls.
