The Flare

Question 1

When a helicopter flares prior to touchdown, one component of total rotor thrust acts (forward, rearward) while the other component acts (upward, downward) to control (height, airspeed)

Answer 1

Rearward
Upward
Height

Question 2

During the flare the induced flow (increases, decreases) as the result as an airflow from (above, below) the rotor disc.

Answer 2

Decreases
Below

Question 3

If the collective lever is left unchanged during a level flare, the ( greater, smaller) inflow angles cause total rotor thrust to ( increase, decrease) and the aircraft tends to ——-

Answer 3

Smaller
Increase
Climb

Question 4

Rotor rpm tends to ——- during a flare because the (greater, smaller) total rotor thrust causes (blade, coning) angles to increase which results in the blades centre of gravity moving (towards, away from) the axis of rotation. Coriolis effect then (increases, decreases) the rotational velocity of the blade.

Answer 4

Climb
Greater
Coning
Towards
Increase

Question 5

When you initiate a level flare, collective must be (lowered, raised) and (right, left) pedal applied to maintain direction. As the helicopter slows down to a halt you must anticipate (raising, lowering) collective and applying (left, right) pedal to maintain direction

Answer 5

Lowered
Right
Raising
Left

Question 6

If you allow rpm to decay towards the end of the flare, forward movement of cyclic to level the disc (will, will not) assist in raising the rpm it will further—— the rpm.

Answer 6

Will not
Decay
