Question 1

With regard to the take-off performance of a twin jet aeroplane, why does the take-off performance climb limit graph show a kink at 30°C and PA 0'?

Accepted Answer

The engines are pressure limited at lower temperature, at higher temperatures they are temperature limited[see Annex]

Answer

At lower temperatures one has to take the danger of icing into account

Answer

At higher temperatures the VMBE determines the climb limit mass

Answer

At higher temperatures the flat rated engines determines the climb limit mass

Question 2

If the thrust available exceeds the thrust required for level flight

Accepted Answer

The aeroplane accelerates if the altitude is maintained.

Answer

The aeroplane descends if the airspeed is maintained.

Answer

The aeroplane decelerates if the altitude is maintained.

Answer

The aeroplane decelerates if it is in the region of reversed command.

Question 3

A jet aeroplane is climbing with constant IAS. Which operational speed limit is most likely to be reached?

Accepted Answer

The Maximum operating Mach number

Answer

The Stalling speed

Answer

The Mach limit for the Mach trim system

Answer

The Minimum control speed air

Question 4

Which of the following factors leads to the maximum flight time of a glide?

Accepted Answer

Low mass

Answer

High mass

Answer

Tailwind

Answer

Headwind

Question 5

Regarding the obstacle limited take-off mass, which of the following statements is correct?

Accepted Answer

A take-off in the direction of an obstacle is also permitted in tail wind condition

Answer

Wind speed plays no role when calculating this particular mass

Answer

The maximum bank angle which can be used is 10°

Answer

The obstacle limited mass can never be lower than the climb limited take-off mass

Question 6

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 7

A runway is contaminated by a 0.5 cm layer of wet snow. The take-off is nevertheless authorized by a light-twin's flight manual.The take-off distance in relation to a dry runway will be:

Accepted Answer

Increased

Answer

Unchanged

Answer

Decreased

Answer

Very significantly decreased

Question 8

A jet aeroplane equipped with old engines has a specific fuel consumption of 0.06 kg per Newton of thrust and per hour and, in a given flying condition, a fuel consumption of 14 kg per NM. In the same flying conditions, the same aeroplane equipped with modern engines with a specific fuel consumption of 0.035 kg per Newton of thrust and per hour, has a fuel consumption per NM of:

Accepted Answer

8.17 kg / NM

Answer

11.7 kg / NM

Answer

14 kg / NM

Answer

10.7 kg / NM

Question 9

The minimum climb gradient required on the 2nd flight path segment after the take-off of a jet aeroplane is defined by the following parameters:1 Gear up2 Gear down3 Wing flaps retracted4 Wing flaps in take-off position 5 N engines at the take-off thrust6 (N- 1) engines at the take-off thrust7 Speed over the path equal to V2 + 10 kt 8 Speed over the path equal to 1.3 VS9 Speed over the path equal to V210 At a height of 35 ft above the runway The correct statements are:

Accepted Answer

1, 4, 6, 9

Answer

1, 4, 5, 10

Answer

2, 3, 6, 9

Answer

1, 5, 8, 10

Question 10

Which of the alternatives represents the correct relationship?

Accepted Answer

VMCG and V1 should not exceed VR

Answer

V2 and V1 should not exceed VMCA

Answer

V2 and V1 should not exceed VMCG

Answer
