Question 1

Designers fit surfaces that alter the airflow over the wing to improve aerodynamic performance. Which group lists such surfaces?

Accepted Answer

Flaps, spoilers and speed brakes

Answer

Flaps only

Answer

Spoilers and speed brakes only

Question 2

A control surface has been given too much aerodynamic balance. What will the pilot feel as the surface is deflected?

Accepted Answer

The stick force suddenly falls away and then reverses

Answer

The control suddenly loses its effect on the aeroplane

Answer

The stick force suddenly rises

Answer

The stick force builds up gradually as IAS increases

Question 3

An aeroplane flies supersonically and its oblique shock wave sweeps across the ground below. How fast does the shock move over the ground?

Accepted Answer

At the aeroplane's groundspeed

Answer

At TAS plus the wind component

Answer

At TAS minus the wind component

Answer

At the sea level speed of sound

Question 4

Which statement about control surface flutter is true?

Accepted Answer

It is a violent oscillation that has to be prevented inside the flight envelope

Answer

It is used to estimate the safe life of the wing

Answer

It happens only at high angles of attack

Answer

It adds lift at low speed if an engine fails

Question 5

How is the taper ratio of a wing defined?

Accepted Answer

Tip chord divided by root chord

Answer

Root chord divided by tip chord

Answer

Mean chord divided by root chord
