Question 1

Question
Why are 'step climbs' used on long distance flights ?
Answer
  • Step climbs do not have any special purpose for jet aeroplanes; they are used for piston engine aeroplanes only.
  • To respect ATC flight level constraints.
  • To fly as close as possible to the optimum altitude as aeroplane mass reduces.
  • Step climbs are only justified if at the higher altitude less headwind or more tailwind can be expected.

Question 2

Question
If the take-off mass of an aeroplane is brake energy limited a higher uphill slope would
Answer
  • have no effect on the maximum mass for take-off.
  • decrease the required take-off distance.
  • increase the maximum mass for take-off.
  • decrease the maximum mass for take-off.

Question 3

Question
The approach climb requirement has been established so that the aeroplane will achieve:
Answer
  • manoeuverability during approach with full flaps and gear down, all engines operating.
  • minimum climb gradient in the event of a go-around with one engine inoperative.
  • obstacle clearance in the approach area.
  • manoeuverability in the event of landing with one engine inoperative.

Question 4

Question
In which of the following distances can the length of a stopway be included?
Answer
  • In the accelerate stop distance available.
  • In the one-engine failure case, take-off distance
  • In the all-engine take-off distance
  • In the take-off run available

Question 5

Question
For jet aeroplanes which of the following statements is correct?
Answer
  • When determining the maximum allowable landing mass at destination, 60% of the available distance is taken into account, if the runway is expected to be dry.
  • In any case runway slope is one of the factors taken into account when determining the required landing field length.
  • An anti-skid system malfunction has no effect on the required landing field length.
  • The required landing field length is the distance from 35 ft to the full stop point.

Question 6

Question
On a dry runway the accelerate stop distance is increased
Answer
  • by headwind.
  • by low outside air temperature.
  • by a lower take-off mass because the aeroplane accelerates faster to V1.
  • by uphill slope.

Question 7

Question
With regard to a unaccelerated horizontal flight, which of the following statement is correct?
Answer
  • The minimum drag is independant of the aircraft mass.
  • The minimum drag is proportional to the aircraft mass.
  • The minimum drag is a function of the pressure altitude.
  • The minimum drag is is a function of the density altitude.

Question 8

Question
With an true airspeed of 194 kt and a vertical speed of 1 000 ft/min, the climb gradient is about :
Answer
  • 3°
  • 3%
  • 5°
  • 8%

Question 9

Question
Concerning the landing gear, which of the following factors would limit the take-off mass?
Answer
  • Nitrogen pressure in the strut and brake temperature.
  • Rate of rotation of the wheel at lift off and brake energy
  • Tyre pressure and brake temperature.
  • Rate of rotation of the wheel and tyre pressure.

Question 10

Question
Which of the following speeds can be limited by the 'maximum tyre speed'?
Answer
  • Lift-off groundspeed
  • Lift-off IAS.
  • Lift-off TAS.
  • Lift-off EAS.

Question 11

Question
The maximum operating altitude for a certain aeroplane with a pressurised cabin
Answer
  • is dependent on aerodynamic ceiling
  • is dependent on the OAT.
  • is only certified for four-engine aeroplanes
  • is the highest pressure altitude certified for normal operation

Question 12

Question
A higher outside air temperature (OAT)
Answer
  • decreases the brake energy limited take-off mass.
  • increases the field length limited take-off mass.
  • increases the climb limited take-off mass.
  • decreases the take-off distance.

Question 13

Question
The stalling speed or the minimum steady flight speed at which the aeroplane is controllable in landing configuration is abbreviated as
Answer
  • VS1.
  • VS.
  • VMC.
  • VSO.

Question 14

Question
If the take-off mass of an aeroplane is tyre speed limited, downhill slope would
Answer
  • increase the maximum mass for take-off.
  • increase the required take-off distance
  • have no effect on the maximum mass for take-off.
  • decrease the maximum mass for take-off.

Question 15

Question
What will be the effect on an aeroplane's performance if aerodrome pressure altitude is decreased?
Answer
  • It will increase the take-off distance required.
  • It will increase the take-off ground run.
  • It will increase the accelerate stop distance.
  • It will decrease the take-off distance required

Question 16

Question
An aeroplane carries out a descent from FL 410 to FL 270 at cruise Mach number, and from FL 270 to FL 100 at the IAS reached at FL 270. How does the angle of descent change in the first and in the second part of the descent? Assume idle thrust and clean configuration and ignore compressibility effects.
Answer
  • Increases in the first part; is constant in the second
  • Increases in the first part; decreases in the second.
  • Is constant in the first part; decreases in the second.
  • Decreases in the first part; increases in the second.

Question 17

Question
A constant headwind component
Answer
  • increases the angle of flight path during climb
  • increases the best rate of climb.
  • decreases the angle of climb.
  • increases the maximum endurance

Question 18

Question
Higher gross mass at the same altitude decreases the gradient and the rate of climb whereas
Answer
  • VY and VX are increased
  • VX is increased and VY is decreased.
  • VY and VX are not affected by a higher gross mass
  • VY and VX are decreased

Question 19

Question
In case of an engine failure which is recognized at or above V1
Answer
  • the take-off should be rejected if the speed is still below VR.
  • the take-off must be continued
  • the take-off must be rejected if the speed is still below VLOF.
  • a height of 50 ft must be reached within the take-off distance.

Question 20

Question
When flying the "Backside of Thrustcurve" means
Answer
  • a lower airspeed requires more thrust.
  • the thrust required is independent of the airspeed.
  • a thrust reduction results in an acceleration of the aeroplane
  • a lower airspeed requires less thrust because drag is decreased.

Question 21

Question
VR cannot be lower than:
Answer
  • 105% of V1 and VMCA.
  • 1.2 Vs for twin and three engine jet aeroplane.
  • 1.15 Vs for turbo-prop with three or more engines.
  • V1 and 105% of VMCA.

Question 22

Question
Given: VS= Stalling speed VMCA= Air minimum control speed VMU= Minimum unstick speed (disregarding engine failure) V1= take-off decision speed VR= Rotation speed V2 min.= Minimum take-off safety speed VLOF: Lift-off speed The correct formula is:
Answer
  • VR< VMCA< VLOF
  • VMU<= VMCA< V1
  • V2min< VMCA> VMU
  • VS< VMCA< V2 min
