Flight Instructors Training Procedures _revised AIC_x

1. AIM
DEFINITION
EXERCISE 12
THE TAKE-OFF AND CLIMB TO THE DOWNWIND POSITION
The take-off is considered to start when the aircraft is accelerated under its own take-off power on the
ground until flying speed is reached, whereupon the aircraft is rotated and leaves the ground. The
speed is now allowed to increase up to the safety speed, at which speed the aircraft is rotated into the
climbing attitude.
WHAT THE INSTRUCTOR IS TO TEACH
i. Discuss the principles involved.
ii The air exercise briefing:
a. Applicable procedures and checklists.
b. Aircraft handling techniques: Demonstration and Observation.
c. Considerations of airmanship and engine handling.
d. Similarity to previous exercises.
e. De-briefing after flight.
WHY IT IS BEING TAUGHT
To give the student a good understanding and thorough knowledge of the principles required to:
i. Control the aircraft on the ground before becoming airborne.
ii. Take account of the different considerations applicable to take-offs under varying weather
conditions.
HOW THE EXERCISE APPLIES TO FLYING
i. Normal take-off.
ii. Short take-off.
iii. First solo.
2. PRINCIPLES INVOLVED
1. GROUND RUN
i. Re-cap on Newton’s Law 1 and 2.
ii. Forces whilst on the ground – Thrust, Drag and Weight.
iii. Thrust – at maximum power available.
iv. Effect of power:
a. Slipstream.
b. Torque.
c. Gyroscopic.
d. Asymmetric Blade Thrust.
v. Drag:
a. Elevator stabiliser position.
b. Tail up movement – applicable to tail wheel aircraft.
c. Surface friction between tyres and runway.
vi. Flaps – discuss the various flap settings which may be used for take-off.
