Free CPL Aerodynamics Questions and Answers

Question 1

What are the effects of extended ailerons?

Accepted Answer

produce greater lift and control during slow flight

Answer

Explanation:
Extended ailerons are designed to protrude past the trailing edge of the wing and produce additional lift during slow flight.

Question 2

The diagram below is a rough incomplete graph of induced drag.

Accepted Answer

When speed is high, induced drag is low, and parasitic drag is high

Answer

Explanation:
Induced drag is directly related to the lift being produced by the wing and hence the angle of attack. At high speed you will have a lower angle of attack otherwise you would climb. This decrease in the angle of attack causes the induced drag to decrease.

Question 3

To achieve an emergency off-field landing with the minimum kinetic energy into a tea tree plantation, the PIC must:

Accepted Answer

land at the lowest possible airspeed

Answer

Explanation:
This question tests your knowledge of kinetic energy. The lower the speed, the lower the kinetic energy.

Question 4

The greatest fuel range for an aircraft will be achieved at:

Accepted Answer

the lowest drag

Answer

Explanation:
To use the lowest energy you need to produce the lowest force. The force being worked against is a drag. So the lowest drag will require the lowest force to move forward and thus the most movement forward for the least fuel.

Question 5

The net effect of all forces acting on an aircraft wing are:

Accepted Answer

none of these

Answer

Explanation:
It is called the total reaction.
