Flight Instructors Training Procedures _revised AIC_x

16. THE GYROSCOPIC EFFECTS OF THE PROPELLER WITH POWER ON
Where the propeller turns clockwise as viewed from the cockpit, an increase in power during
the spin will cause the spin to flatten if spinning to the left and to pitch nose down if spinning to
the right.
17. EFFECT OF FLAP
Discuss the effect of flap on the spin.
18. EFFECT OF MASS AND BALANCE
Discuss the effect of mass and balance distribution on the spin.
3. DESCRIPTION OF AIR EXERCISE
a. APPLICABLE PROCEDURES AND CHECKLISTS
b. AIRCRAFT HANDLING TECHNIQUES:-
DEMONSTRATION OBSERVATION
1. THE STUDENT’S FIRST SPIN
i. The considerations are the same as those for
the student’s first stall, so the first spin should,
therefore, be done at the end of the lesson
preceding that on which spinning is to be taught.
This spin should consist of not more than two
turns. To give the student as little time for
thought and worry it helps if he is kept busy with
flying the aircraft and doing all the necessary
actions right up to the moment of the entry.
2.
i.
SPINS FROM STRAIGHT AND LEVEL
FLIGHT
Demonstrate spins in both directions (lead with
rudder in direction of intended spin).
,,
i. Lookout.
ii. Complete pre-stall checks (HASSELL).
iii. Inspection turn.
iv. No a violent manoeuvre.
v. Ease of recovery.
vi. Check position frequently in relation to
landmarks during the exercise.
i. Lookout.
ii. Pre-stall checks (HASELL).
iii. Entry:
a. As for normal power-off stall.
b. Just prior to the stall, simultaneously
apply full rudder in the direction of the
desired spin and move the control
column fully back.
c. Ensure throttle fully closed.
d. Carb heat as required.
iv. In the spin:
a. Ailerons neutral.
b. Rudder – full on.
c. Control column – fully back.
Note:
a. High rate of descent – altimeter/VSI.
b. Direction of turn needle – position of
ball.
c. No continuous increase in airspeed.
