1) A Krueger flap is Report

a leading edge slat which extends forward.

a flap which extends rearwards but does not lower.

a leading edge flap which hinges forward.

2) The layer of air over the surface of an aerofoil which is slower moving, in relation to the rest of the airflow, is known as Report

camber layer.

boundary layer

none of the above are correct.

3) As the airflow velocity over an upper cambered surface of an aerofoil decreases, the Report

Pressure increases, lift decreases.

Pressure decreases, lift increases.

Pressure increases, lift increases.

4) What factor reduces airflow turbulence and skin friction Report

Aspect ratio

Fineness ratio

Countersunk rivets used on skin exterior.

5) Changes in aircraft weight Report

will only affect total drag if the lift is kept constant.

will not affect total drag since it is dependant only upon speed.

causes corresponding changes in total drag due to the associated lift change.

6) When an aircraft stalls Report

lift decreases and the drag increases.

lift and drag increases

lift and drag decreases

7) The aircraft stalling speed will Report

increase with an increase in weight.

be unaffected by aircraft weight changes since it is dependant upon the angle of attack.

8) In a bank and turn Report

extra lift is required.

pitch up attitude is required.

extra lift is not required if thrust is increased.

9) The angle of attack at which stall occurs Report

is always constant

depends on the weight of the aircraft.

can be varied by using flaps and slats.

10) The primary function of a flap is Report

to alter the position of the centre of gravity.

to trim the aircraft longitudinally.

to alter the lift of an aerofoil.

11) The stalling speed of an aircraft Report

increases as the weight decreases

increases as the weight increases

does not vary with the weight change

12) Partially extended flap on a wing in flight will lead to Report

a steady rolling tendency that can be corrected by use of the ailerons.

a fixed banked attitude that can be corrected by use of the rudder.

a pitching moment that can be corrected by used of the elevators.

13) When the flaps are deployed, the stalling angle of a wing would Report

increase

decrease

remain the same

14) Downward displacement of an aileron Report

decreases the angle at which its wing will stall.

increases the angle at which its wing stalls.

has no effect on its wing stalling angle, it only affects the stalling speed on that wing.

15) When the angle of attack on a tailplane changes, the flap-induced downwash on the tailplane Report

may cause a nose-down or nose-up pitch depending upon the initial tailplane load.

will tend to pitch down the aircraft nose.

will tend to pitch up the aircraft nose

16) Lift coefficient changes due to extension of flaps, what action should be taken to maintain a constant Lift Report

Lower the nose

Raise the nose

Keep the pitch attitude constant

17) Which leading edge device improves the laminar flow over the wing Report

Flap

Slat

Flap and Slat

18) The tropopause exists at about Report

18,000 ft.

30,000 ft.

36,000 ft.

19) Induced drag curve characteristics of a ?slender delta? wing are such that there is Report

an increase in gradient with wing speed.

a decrease in gradient with wing speed.

no change in gradient with wing speed.

20) An aircraft entering into a roll and yaw attitude is called Report

Duch roll

Longitudinal stability

Lateral stability
