Accepted Answer

Small aspect ratio

Answer

Large aspect ratio

Answer

Tapered wings

Answer

Low lift coefficients

Question 2

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

Answer

Greater than in a climb.

Answer

Greater than at take-off

Answer

Smaller than in a descent

Question 3

Which effect does a decreasing airspeed have on the induced drag during a horizontal and stable cruise flight?

Accepted Answer

The induced drag will increase

Answer

The induced drag will collapse

Answer

The induced drag will remain constant

Answer

The induced drag will slightly decrease

Question 4

Stability around which axis is mainly influenced by the center of gravity's longitudinal position?

Accepted Answer

Lateral axis

Answer

Vertical axis

Answer

Longitudinal axis

Answer

Gravity axis

Question 5

How should the pilot react to an engaged stall warning?

Accepted Answer

Push the elevator, increase power

Answer

Pull the elevator, increase power

Answer

Pull the elevator, decrease power

Answer

Raise the nose to decrease airspeed

Question 6

During a straight and steady climb, which force acts addionally, and in the same direction as the drag force, resulting in more power required for climb than for horizontal flight?

Accepted Answer

A component of the weight force along the rearward flight path

Answer

The vertical component of the weight force

Answer

A component of the thrust along the rearward flightpath.

Answer

A component of the lift force along the forward flightpath.

Accepted Answer

Aspect ratio.

Answer

Trapezium shape.

Answer

Tapering

Answer

Wing sweep.

Question 8

In which way does the position of the center of pressure move at a positively shaped profile with increasing angle of attack?

Accepted Answer

It moves forward until reaching the critical angle of attack

Answer

It moves backward until reaching the critical angle of attack

Answer

It moves forward first, then backward

Answer

It moves to the wing tips

Question 9

Point number 5 in the figure indicates which flight state? See figure (PFA-008) (1,00 P.) Siehe Anlage 5

Accepted Answer

Slow flight

Answer

Accepted Answer

The trim condition

Answer

The position of the center of gravity

Answer

The effectiveness of the ailerons

Answer

The twist effect of the engine
