Question 1

In a co-ordinated turn, how is the relation between the load factor (n) and the stall speed (Vs)?

Accepted Answer

N is greater than 1, Vs is greater than in straight and level flight

Answer

N is smaller than 1, Vs is greater than in straight and level flight

Answer

N is greater than 1, Vs is smaller than in straight and level flight

Answer

N is smaller than 1, Vs is smaller than in straight and level flight

Question 2

What describes "wing loading"?

Accepted Answer

Weight per wing area

Answer

Wing area per weight

Answer

Drag per weight

Answer

Drag per wing area

Question 3

Differential aileron deflection is used to...

Accepted Answer

Keep the adverse yaw low

Answer

Reduce wake turbulence

Answer

Avoid a stall at low angles of attack

Answer

Increase the rate of descent

Question 4

What leads to a decreased stall speed Vs (IAS)?

Accepted Answer

Decreasing weight

Answer

Lower density

Answer

Lower altitude

Answer

Higher load factor

Question 5

In straight and level flight with constant performance of the engine, the angle of attack at the wing is...

Accepted Answer

Smaller than in a climb

Question 7

At stationary glide and the same mass, what is the difference when using a thick airfoil instead of a thinner airfoil?

Accepted Answer

More drag, same lift
