Principles of Flight – Self-Assessment Exercise

Angle of attack on a aerofoil is:

As air density increases, the amount of lift an aerofoil can produce:

If the speed of our aircraft doubles, the amount of lift the aerofoil produces:

The weight force of an aircraft always:

Thrust is produced by:

Drag caused by the production of lift is called:

As airspeed increases:

Air particles on the surface of a moving object are:

Flap-type controls (e.g. ailerons) operate on the principal:

A trimmer is used to:

An aircraft rolls about which axis?

Lift is generated through:

The secondary effect of rudder is:

The further effect of aileron is:

To stop adverse aileron yaw:

An increase in airspeed will:

The slipstream from the propeller will increase the effectiveness of:

If the Angle of Attack is increased on the elevator, the aircrafts nose will:

Lowering flaps will:

Stability in the rolling plane is called:

Flying with a higher airspeed than normal in straight and level flight will give a:

Service ceiling is when an aircraft:

Positive lateral stability is achieved by:

In a climb a headwind will affect:

Vy (best rate of climb) is achieved at the speed of:

Vx (best angle of climb) is achieved at the speed of:

Positive longitudinal stability is achieved by a:

Positive directional stability is achieved by:

In a descend without power (engine failure) with a heavier aircraft than normal:

The lift force always:
