Question
99) During the certification flight testing of a twin engine turbojet aeroplane, the real take-off distances are equal to: - 1547 m with all engines running - 1720 m with failure of critical engine at V1, with all other things remaining unchanged. The take-off distance adopted for the certification file is:
Answer
  • 1547 m.
  • 1720 m.

Question 3

Question
The minimum value of V2 must exceed "air minimum control speed" by:
Answer
  • 15%
  • 20%
  • 30%
  • 10%

Question 4

Question
102) With regard to a take-off from a wet runway, which of the following statements is correct?
Answer
  • Screen height cannot be reduced.
  • The screen height can be lowered to reduce the mass penalties.
  • When the runway is wet, the V1 reduction is sufficient to maintain the same margins on the runway length.
  • In case of a reverser inoperative the wet runway performance information can still be used.

Question 5

Question
103) On a reciprocating engined aeroplane, to maintain a given angle of attack, configuration and altitude at higher gross mass
Answer
  • an increase in airspeed is required but power setting does not change.
  • requires an increase in power and decrease in the airspeed.
  • an increase in airspeed and power is required.
  • a higher coefficient of drag is required.

Question 6

Question
104) The first segment of the take-off flight path ends
Answer
  • at completion of gear retraction.
  • at completion of flap retraction.
  • at reaching V2.
  • at 35 ft above the runway.

Question 7

Question
105) Which of the following factors favours the selection of a low flap setting for the take-off?
Answer
  • High field elevation, no obstacles in the climb-out path, low ambient temperature and short runway.
  • Low field elevation, no obstacles in the climb-out path, short runway and a low ambient temperature.
  • High field elevation, distant obstacles in the climb-out path, long runway and a high ambient temperature.
  • Low field elevation, close-in obstacles in the climb-out path, long runway and a high ambient temperature.

Question 8

Question
106) Balanced V1 is selected
Answer
  • for a runway length limited take-off with a clearway to give the highest mass.
  • if it is equal to V2.
  • if the accelerate stop distance is equal to the one engine out take-off distance.
  • for a runway length limited take-off with a stopway to give the highest mass.

Question 9

Question
108) For jet-engined aeroplanes, what is the effect of increased altitude on specific range?
Answer
  • Does not change.
  • Increases only if there is no wind.
  • Increases.
  • Decreases.

Question 10

Question
96) The speed for best rate of climb is called:
Answer
  • VO.
  • VY.
  • VX.
  • V2.

Question 11

Question
110) Two identical aeroplanes at different masses are descending at idle thrust. Which of the following statements correctly describes their descent characteristics ?
Answer
  • At a given angle of attack, both the vertical and the forward speed are greater for the heavier aeroplane.
  • There is no difference between the descent characteristics of the two aeroplanes.
  • At a given angle of attack the heavier aeroplane will always glide further than the lighter aeroplane.
  • At a given angle of attack the lighter aeroplane will always glide further than the heavier aeroplane.

Question 12

Question
111) ETOPS flight is a twin engine jet aeroplane flight conducted over a route, where no suitable airport is within an area of
Answer
  • 75 minutes flying time at the approved one engine out cruise speed.
  • 60 minutes flying time in still air at the approved one engine out cruise speed.
  • 60 minutes flying time in still air at the normal cruising speed.
  • 30 minutes flying time at the normal cruising speed.

Question 13

Question
112) For a take-off from a contaminated runway, which of the following statements is correct?
Answer
  • Dry snow is not considered to affect the take-off performance.
  • A slush covered runway must be cleared before take-off, even if the performance data for contaminated runway is available.
  • The performance data for take-off must be determined in general by means of calculation, only a few values are verified by flight tests.
  • The greater the depth of contamination at constant take-off mass, the more V1 has to be decreased to compensate for decreasing friction.

Question 14

Question
113) If the thrust available exceeds the thrust required for level flight
Answer
  • the aeroplane accelerates if the altitude is maintained.
  • the aeroplane descends if the airspeed is maintained.
  • the aeroplane decelerates if it is in the region of reversed command.
  • the aeroplane decelerates if the altitude is maintained.

Question 15

Question
114) Which statement regarding the relationship between traffic load and range is correct?
Answer
  • The maximum landing mass is basically equal to the maximum zero fuel mass.
  • The maximum traffic load is not limited by the reserve fuel quantity.
  • The traffic load can be limited by the desired range.
  • The maximum zero fuel mass limits the maximum quantity of fuel.

Question 16

Question
115) The induced drag of an aeroplane
Answer
  • is independent of the airspeed.
  • increases with increasing airspeed.
  • decreases with increasing airspeed.
  • decreases with increasing gross weight.

Question 17

Question
116) Which statement, in relation to the climb limited take-off mass of a jet aeroplane, is correct?
Answer
  • 50% of a head wind is taken into account when determining the climb limited take-off mass.
  • On high elevation airports equipped with long runways the aeroplane will always be climb limited.
  • The climb limited take-off mass decreases with increasing OAT.
  • The climb limited take-off mass is determined at the speed for best rate of climb.

Question 18

Question
117) How is V2 affected if T/O flaps 20° is chosen instead of T/O flaps 10°?
Answer
  • V2 increases in proportion to the angle at which the flaps are set.
  • V2 has no connection with T/O flap setting, as it is a function of runway length only.
  • V2 decreases if not restricted by VMCA.
  • V2 has the same value in both cases.

Question 19

Question
118) Which of the jet engine ratings below is not a certified rating?
Answer
  • Go-Around Thrust
  • Maximum Take-off Thrust
  • Maximum Cruise Thrust
  • Maximum Continuous Thrust

Question 20

Question
107) Which statement regarding the influence of a runway down-slope is correct for a balanced take-off? Down- slope...
Answer
  • increases V1 and reduces the accelerate stop distance required (ASDR).
  • reduces V1 and increases the accelerate stop distance required (ASDR).
  • increases V1 and increases the take-off distance required (TODR).
  • reduces V1 and reduces take-off distance required (TODR).
