Question 1

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 2

On a long distance flight the gross mass decreases continuously as a consequence of the fuel consumption. The result is:

Accepted Answer

The specific range and the optimum altitude increase.

Answer

The specific range increases and the optimum altitude decreases.

Answer

The speed must be increased to compensate the lower mass.

Answer

The specific range decreases and the optimum altitude increases.

Question 3

The speed V2 is defined for jet aeroplane as:

Accepted Answer

Take-off climb speed or speed at 35'

Answer

Take-off decision speed

Answer

Lift off speed

Answer

Critical engine failure speed

Question 4

An aeroplane executes a steady glide at the speed for minimum glide angle. If the forward speed is kept constant, what is the effect of a lower mass? Rate of descent / Glide angle / CL / CD ratio

Accepted Answer

Increases / increases / decreases

Answer

Increases / constant / increases

Answer

Increases / increases / constant

Answer

Decreases / constant / decreases

Question 5

Long range cruise is a flight procedure which gives:

Accepted Answer

A specific range which is approximately 99% of maximum specific range and a higher cruise speed

Answer

A specific range which is approximately 99% of maximum specific range and a lower cruise speed

Answer

An IAS which is 1% higher than the IAS for maximum specific range

Answer

A 1% higher TAS for maximum specific range

Question 6

In straight horizontal steady flight, at speeds below that for minimum drag:

Accepted Answer

A lower speed requires a higher thrust.

Answer

The aeroplane cannot be controlled manually.

Answer

A higher speed, but still below that for minimum drag, requires a higher thrust.

Answer

The aeroplane can be controlled only in level flight.

Question 7

Below the optimum cruise altitude:

Accepted Answer

The Mach number for long range cruise decreases continuously with decreasing altitude

Answer

The IAS for long range cruise increases continuously with decreasing altitude

Answer

The TAS for long range cruise increases continuously with decreasing altitude

Answer

The Mach number for long range cruise increases continuously with decreasing altitude

Question 8

What is the effect of a headwind component, compared to still air, on the maximum range speed (IAS) and the speed for maximum climb angle respectively?

Accepted Answer

Maximum range speed increases and maximum climb angle speed stays constant

Answer

Maximum range speed decreases and maximum climb angle speed increases

Answer

Maximum range speed decreases and maximum climb angle speed decreases

Answer

Maximum range speed increases and maximum climb angle speed increases

Question 9

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 10

In twin-jet take-off performance, why can the climb-limit mass curve have a kink at about 30°C and pressure altitude 0 ft?

Accepted Answer

The engines are pressure limited at lower temperature, at higher temperatures they are temperature limited

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
