Question 1

The use of reduced take-off thrust is permitted, only if:

Accepted Answer

The actual take-off mass (TOM) is lower than the field length limited TOM

Answer

The actual take-off mass (TOM) including a margin is greater than the performance limited TOM

Answer

The take-off distance available is lower than the take-off distance required one engine out at V1

Answer

The actual take-off mass (TOM) is greater than the climb limited TOM

Question 2

A jet aeroplane is climbing at a constant IAS and maximum climb thrust, how will the climb angle / the pitch angle change?

Accepted Answer

Reduce / decrease

Answer

Reduce / remain constant

Answer

Remain constant / become larger

Answer

Remain constant / decrease

Question 3

With regard to the drift down performance of the twin jet aeroplane, why does the curve representing 35000 kg gross mass in the chart for drift down net profiles start at approximately 4 minutes at FL370?

Accepted Answer

Because at this mass it takes approximately 4 minutes to decelerate to the optimum speed for drift down at the original cruising level

Answer

Due to higher TAS at this mass it takes more time to develop the optimal rate of descent, because of the inertia involved

Answer

Because at this mass the engines slow down at a slower rate after failure, there is still some thrust left during four minutes

Answer

All the curves start at the same point, which is situated outside the chart

Question 4

A climb gradient required is 3.3%. For an aircraft maintaining 100 KT true airspeed, no wind, this climb gradient corresponds to a rate of climb of approximately:

Accepted Answer

330 fpm

Answer

3300 fpm

Answer

33.0 m/s

Answer

3.30 m/s

Question 5

Any acceleration in climb, with a constant power setting:

Accepted Answer

Decreases the rate of climb and the angle of climb

Answer

Improves the rate of climb if the airspeed is below VY

Answer

Improves the climb gradient if the airspeed is below VX

Answer

Decreases rate of climb and increases angle of climb

Question 6

The take-off runway performance requirements for transport category aeroplanes are based upon:

Accepted Answer

Failure of the critical engine or all engines operating whichever requirement gives the greater distance

Answer

All engines operating only

Answer

One engine inoperative only

Answer

Failure of the critical engine only

Question 7

During a descent at constant Mach number, the margin to low speed buffet will:

Accepted Answer

Increase, because the lift coefficient decreases.

Answer

Remain constant, because the Mach number remains constant.

Answer

Increase, because the lift coefficient increases.

Answer

Decrease, because the lift coefficient decreases.

Question 8

The best rate of climb at a constant gross mass:

Accepted Answer

Decreases with increasing altitude since the thrust available decreases due to the lower air density

Answer

Increases with increasing altitude due to the higher true airspeed

Answer

Increases with increasing altitude since the drag decreases due to the lower air density

Answer

Is independent of altitude

Question 9

The maximum indicated air speed of a piston engine aeroplane without turbo charger, in level flight, is reached:

Accepted Answer

At the lowest possible altitude

Answer

At the optimum cruise altitude

Answer

At the practical ceiling

Answer

At the service ceiling

Question 10

The optimum long-range cruise altitude for a turbojet aeroplane:

Accepted Answer

Increases when the aeroplane mass decreases

Answer

Is always equal to the powerplant ceiling

Answer

Is independent of the aeroplane mass

Answer

Is only dependent on the outside air temperature
