Question 1

Under which condition should you fly considerably lower (4 000 ft or more) than the optimum altitude?

Accepted Answer

If at the lower altitude either considerably less headwind or considerably more tailwind can be expected.

Answer

If the maximum altitude is below the optimum altitude.

Answer

If at the lower altitude either more headwind or less tailwind can be expected.

Answer

If the temperature is lower at the low altitude (high altitude inversion).

Question 2

The force exactly opposing and balance lift in a glide descent is:

Accepted Answer

Weight x cos(angle of descent)

Answer

Thrust x sin(angle of descent)

Answer

Weight x sin(angle of descent)

Answer

Thrust x cos(angle of descent)

Question 3

If a flight is performed with a higher 'Cost Index' at a given mass which of the following will occur?

Accepted Answer

A higher cruise Mach number.

Answer

A lower cruise Mach number.

Answer

An increased maximum range.

Answer

An increased long range performance.

Question 4

The speed V2 is:

Accepted Answer

The take-off safety speed

Answer

The lowest airspeed required to retract flaps without stall problems

Answer

That speed at which the PIC should decide to continue or not the take-off in the case of an engine failure

Answer

The lowest safety airspeed at which the aeroplane is under control with aerodynamic surfaces in the case of an engine failure

Question 5

The pilot of a single engine aircraft has established the climb performance. The carriage of an additional passenger will cause the climb performance to be:

Accepted Answer

Degraded

Answer

Improved

Answer

Unchanged

Answer

Unchanged, if a short field take-off is adopted

Question 6

The net flight path gradient after take-off compared to the actual climb gradient is:

Accepted Answer

Smaller

Answer

Depends on type of aircraft and may be smaller or larger respectively

Answer

Equal

Answer

Larger

Question 7

Why are 'step climbs' used on long distance flights?

Accepted Answer

To fly as close as possible to the optimum altitude as aeroplane mass reduces.

Answer

To respect ATC flight level constraints.

Answer

Step climbs do not have any special purpose for jet aeroplanes

Answer

They are used for piston engine aeroplanes only.

Question 8

Which of the following factors determines the maximum flight altitude in the 'Buffet Onset Boundary' graph?

Accepted Answer

Aerodynamics

Answer

Service ceiling

Answer

Theoretical ceiling

Answer

Economy

Question 9

If the take-off mass of an aeroplane is brake energy limited a higher uphill slope would:

Accepted Answer

Increase the maximum mass for take-off

Answer

Decrease the maximum mass for take-off

Answer

Decrease the required take-off distance

Answer

Have no effect on the maximum mass for take-off

Question 10

In case of an engine failure recognized below V1:

Accepted Answer

The take-off must be rejected

Answer

The take-off is to be continued unless V1 is less than the balanced V1

Answer

The take-off should only be rejected if a stopway is available

Answer

The take-off may be continued if a clearway is available
