Question 4

According to Bernoulli's principle, what happens to static pressure where the speed of airflow increases?

Accepted Answer

It decreases

Answer

It increases

Answer

It stays the same

Question 5

If the true airspeed of an aircraft is doubled at the same angle of attack and density, how much does lift change?

Accepted Answer

4 times

Answer

2 times

Answer

8 times

Question 6

What is the angle of incidence?

Accepted Answer

Fixed angle of wing chord to the longitudinal axis

Answer

Angle of chord to the relative airflow

Answer

Angle of the wing above horizontal from the front

Question 7

How does a symmetrical aerofoil behave at zero angle of attack?

Accepted Answer

It produces no lift

Answer

It produces maximum lift

Answer

It is stalled

Question 8

What happens when the critical angle of attack is exceeded?

Accepted Answer

Flow separates, lift falls and the wing stalls

Answer

Lift keeps increasing but more slowly

Answer

Drag falls sharply as the flow detaches

Question 9

How does induced drag change as airspeed increases in level flight?

Accepted Answer

It decreases

Answer

It increases

Answer

It stays constant

Question 10

What is dynamic pressure?

Accepted Answer

½ ρ V², the pressure due to the motion of the air

Answer

The pressure of still air

Answer

The pressure at the stagnation point minus total pressure

Accepted Answer

71 kt

Answer

100 kt

Answer
