Concepts & Maneuvers

Question 1

Forces Acting on Airplane

Answer 1

The four forces are lift, weight, thrust, and drag. These forces act on an aircraft in flight, and their balance determines the aircraft’s motion.

Question 2

Function of a Propeller

Answer 2

Convert the torque or the turning movement of the crankshaft into thrust or forward speed.

Question 3

Function of Elevators

Answer 3

To divide the energy produced by the engine in the form of thrust, into speed and altitude.

Question 4

Steps to Make a Power Approach

Answer 4

1. Reduce power.
2. Allow aeroplane to slow to approach speed.
3. Adjust desired angle of descent.
4. Maintain constant airspeed and regulate rate of descent by manipulation of power.

Normal recommended airspeed for power-on approach to short field landings is 1.3 times the power-off stalling speed.

Question 5

The Steeper the Angle of Bank in a Turn - For any given airspeed:

Answer 5

1. Greater the rate of turn.
2. Less the radius of turn.
3. Higher the stalling speed.
4. Greater the loading.

Question 6

The Higher the Airspeed - For any given angle of bank:

Answer 6

1. Slower the rate of turn.
2. Larger the radius of turn.

Question 7

Factors Affecting Stall

Answer 7

1. Weight.
2. Center of gravity.
3. Turbulence.
4. Turns.
5. Flaps.
6. Snow, Frost and Ice.
7. Heavy Rain.

Question 8

Stall Recovery

Answer 8

1. Lower the nose to decrease the angle of attack.
2. Apply more power to accelerate the aeroplane. If however, the aeroplane is already under full power when the stall occurs, the only option for recovery from stall is to lower the nose of the aeroplane.

Question 9

Spin Maneuver Stages

Answer 9

1. Incipient stage - Occurs from time the aeroplane stalls and rotation starts until the spin axis becomes vertical or nearly vertical.
2. Developed stage - Angles and motions of aeroplane are stabilized and the flight path is nearly vertical.
3. Recovery.

Question 10

Spin Recovery Maneuver for Light Aeroplanes

Answer 10

1. Power to idle, ailerons neutralized.
2. Apply and hold full rudder opposite to the direction of the rotation.
3. Control column positively forward far enough to unstall the aeroplane.
4. When full rotation stops, neutralize the rudder, level the wings and recover smoothly from the resulting dive.

Question 11

Recovery Maneuver from Spiral Dive

Answer 11

Must be done promptly and in this sequence:
1. Close the throttle and level the wings as nearly simultaneously as possible.
2. Keep straight.
3. Ease out of the dive.
4. Apply power as required to maintain altitude.
