302 Outcome 8

What is Asymmetric flap operation?

• The flaps move together

• One flap moves and the other flap stays in its position

• Movement at slow speed

• Movement at high speed

How does leading edge droop increase lift

• by decreasing the wing camber

• By increasing the wing camber

• by Controlling the boundary layer

• by Controlling the laminar airflow

Which flap gives the greatest increase in lift

• Slotted flap

• Plain flap

• Fowler flap

• Split flap

Which one of the following devices fitted on the upper surface of the wing reduces lift and increases drag>

• Vortex amp meter

• Horizontal fences

• Spoilers

• Dog tooth (saw tooth)

Lift dumpers are used on the ground to

• Reduce drag

• Reduce the lift of the wing and improve wheel brake traction

• Increase lift

• Reduce the lift of the aircraft only

A ratio between lift pressure and dynamic pressure is called

• Lift coefficient

• Drag coefficient

• Pressure coefficient

• Dynamic coefficient

Air brakes are designed specifically to

• Reduce drag and reduce speed of the aircraft

• Increase thrust and increase weight of the aircraft

• Increase drag and increase the speed of the aircraft

• Increase drag and reduce the speed of the aircraft

Which method is used for controlling boundary layer air

• Adverse yawing

• Blown air with wing leading edge slots

• Raising the ailerons

• Asymmetric flaps

What is the purpose of a wing fence?

• To make spanwise flowing air move in a chord wise direction

• To keep the air on the wing

• To make chord wise flowing air move in a spanwise direction

• To direct air over and under the wing

A lift enhancement device fitted to the leading edge of a wing is known as

• Plain flaps

• Split flaps

• Kruger flaps

• Slotted flaps
