Principle of Flight - PPL(A) - Private Pilot License

Question 1

During cruise flight with constant power setting, an aircraft shows a permanent tendency to raise the nose. How can this tendency be eliminated?

Accepted Answer

By deflecting the elevator trim tab upwards

Answer

By shifting the center of gravity backwards

Answer

By elevator deflection upwards

Answer

By deflecting the elevator trim tab downwards

Question 2

The static pressure of gases work...

Accepted Answer

In all directions.

Answer

Only vertical to the flow direction.

Answer

Only in the direction of the total pressure.

Answer

Only in flow direction

Question 3

The elevator moves an aeroplane around the...

Accepted Answer

Lateral axis.

Answer

Elevator axis.

Answer

Longitudinal axis

Answer

Vertical axis.

Question 4

What has to be considered with regard to the center of gravity position?

Accepted Answer

Only correct loading can assure a correct and safe center of gravity position

Answer

The center of gravity's position can only be determined during flight.

Answer

By moving the elevator trim tab, the center of gravity can be shifted into a correct position

Answer

By moving the aileron trim tab, the center of gravity can be shifted into a correct position.

Question 5

Flying with speeds higher than the never-exceed-speed (vNE) may result in...

Accepted Answer

Flutter and mechanically damaging the wings.

Answer

Too high total pressure resulting in an unusable airspeed indicator.

Answer

An increased lift-to-drag ratio and a better glide angle

Answer

Reduced drag with increased control forces

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.

Question 7

The bank in a two-minute turn (rate one turn) depends on the...

Accepted Answer

TAS

Answer

Weight

Answer

Wind

Answer

Load factor.

Question 8

All aerodynamic forces can be considered to act on a single point. This point is called...

Accepted Answer

Center of pressure.

Answer

Center of gravity.

Answer

Lift point.

Answer

Transition point.

Question 9

The center of pressure is the theoretical point of origin of...

Accepted Answer

All aerodynamic forces of the profile

Answer

Only the resulting total drag.

Answer

Gravity forces of the profile

Answer

Gravity and aerodynamic forces

Question 10

Through which factor listed below does the load factor increase during cruise flight?

Accepted Answer

An upward gust

Answer

A forward centre of gravity

Answer

Higher aeroplane weight

Answer

Lower air density
