Flight Instructors Training Procedures _revised AIC_x

6. EFFECT OF POWER
i.
Demonstrate the effects of power changes.
At 55% power, trim the aircraft to fly hands
and feet off. Then increase the power to climb
power.
ii. At climb power, trim the aircraft hands and
feet off. Now close the throttle.
7. EFFECT OF FLAP AND UNDERCARRIAGE
Using a power setting that will not allow the
speed to exceed Vfe (maximum flap extend
speed), trim the aircraft for straight and level
flight, hands and feet off. Re-trim level after
initial observation of flap effect.
)
SEQUENCE OF CHANGING MIXTURE, BOOST
AND PITCH:-
i. Increase power: Mixture richen – Pitch
increase – Throttle open.
ii. Decrease power: Throttle close – Pitch
reduce – Mixture adjust.
INCREASING POWER:-
i. Yaw due to slipstream.
ii. Nose rises because of couple changes and
increased lift.
DECREASING POWER:-
i. Yaw.
ii. Nose drops.
i. Lower optimum flap. i. Note attitude and airspeed before lowering
flap.
ii. Flap selected (maximum speed Vfe) – note
pitch attitude change.
iii. When countered by elevators:
a. Trim change.
b. Lower airspeed.
ii. Re-trim aircraft for level flight, then lower full
flap.
i. Note pitch attitude change.
ii. Note airspeed change.
iii. Note trim change.
iii. Raise flaps to optimum. i. Note attitude and airspeed before raising
flap to optimum.
ii. Flap raised to optimum:
iii. Slight sink.
iv. Note pitch change.
v. When countered by elevators:
vi. Trim change.
vii. Increasing airspeed.
iv. Raise flaps fully. i. Observations the same as for raising flaps
to optimum setting.
ii. Observe change in sink and change of trim.
