BAK - Principles of Flight (Flight Control)

Question 1

How is the pitch of an aircraft controlled?

Answer 1

Elevators - via control column inputs

Question 2

What is the movement that occurs around the longitudinal axis and how is it controlled?

Answer 2

Roll - ailerons - via control column inputs

Question 3

What primary control is used to control yaw?

Answer 3

Vertical fin rudder - via pedal inputs

Question 4

The initial effect of the rudder is to yaw (turn) the aircraft. If held without manipulation of other controls, what is the further effect of rudder use?

Answer 4

roll in the direction of the yaw

Question 5

If the right aileron is deflected down and held (without further manipulation of other controls), what will the aircraft initially do?

If the aircraft then sideslips to the left, what might be the final effect?

Answer 5

initially roll to the left then yaw to the left (right wing further lifted)

Question 6

What further effect does moving the elevator upwards do to airspeed?

Answer 6

decrease (airspeed)

Question 7

Do the primary controls become more or less effective (or sensitive) with an increase in IAS?

Answer 7

more effective with increasing IAS

Question 8

In which direction will the nose pitch if the control column/ wheel is pushed forward?

Answer 8

pitch down

Question 9

Does an increase in airspeed pitch the nose up or down?

Answer 9

down

Question 10

Does an increase in airspeed make the primary controls feel sloppy or more difficult to deflect?

Answer 10

more difficult to deflect

Question 11

Is the effectiveness of the elevators and rudders increased or decreased with an increase in power?

Answer 11

effectiveness is increased due to propeller slipstream effect

Question 12

What are the ailerons unaffected by an increase in power?

Answer 12

outside the influence of propeller slipstream

Question 13

For a clockwise rotating propellor (as viewed from cockpit), what effect does increasing power have on aircraft movement about the normal axis, and how can this movement be counteracted?

Answer 13

tendency for the aircraft to yaw to the left, counteracted by right rudder input

Question 14

An increase in power tends to do what to the the pitch of the aircraft?

Answer 14

pitch nose up

Question 15

How will an increase in airspeed alter the pitch trim of the aircraft?

Answer 15

pitch trim up (forward)

Question 16

Will a steeper approach path and shorter landing distance required be achieved by lowering or raising flaps?

Answer 16

lowering flaps

Question 17

Will raising the flaps during level flight cause the aircraft to balloon or sink?

Answer 17

sink

Question 18

If the CoG is towards or at its aft limit, is the risk of stalling on take-off increased or decreased?

Answer 18

increased

Question 19

It is likely to be difficult to recover from stalls if the CoG is towards or at its forward or aft limit?

Answer 19

aft limit
