Controls: DGCA Technical General questions

Question 1

Spoilers on the upper surface of the wing may be used on landing:

Accepted Answer

To reduce the lift and so put more weight on the wheels, making the brakes more effective.

Answer

To give a nose-down pitching moment.

Answer

To cause drag and increase the lift from the flaps.

Answer

To reduce the touchdown speed.

Question 2

The higher speed of the upper wing in a steady banked turn causes it to have more lift than the lower wing. This may be compensated for by:

Accepted Answer

Operating the ailerons slightly in the opposite sense once the correct angle of bank has been reached.

Answer

Use of the rudder control.

Answer

Increasing the nose-up pitch by using the elevators.

Question 3

Control overbalance results in:

Accepted Answer

A sudden reduction then reversal of stick force.

Answer

A sudden increase in stick force.

Answer

A sudden loss of effectiveness of the controls.

Answer

A gradual increase in stick force with increasing IAS.

Question 4

When displacing the ailerons from the neutral position:

Accepted Answer

The down-going aileron causes an increase in induced drag.

Answer

The up-going aileron causes an increase in induced drag.

Answer

Both cause an increase in induced drag.

Answer

Induced drag remains the same, the up-going aileron causes a smaller increase in profile drag than the down-going aileron.

Question 5

If the ailerons are deflected to 10°, compared to 5°, this will cause:

Accepted Answer

An increased rate of roll.

Answer

An increased angle of bank.

Answer

No change to either bank angle or roll rate.

Answer

A reduction in the adverse yawing moment.
