Question 1

Question
The take-off distance of an aircraft is 800m in standard atmosphere, no wind at 0 ft pressure-altitude. Using the following corrections : "± 20 m / 1 000 ft field elevation " "- 5 m / kt headwind " "+ 10 m / kt tail wind " "± 15 m / % runway slope " "± 5 m / °C deviation from standard temperature " The take-off distance from an airport at 2 000 ft elevation, temperature 21°C, QNH 1013.25 hPa, 2% upslope, 5 kt tail wind is :
Answer
  • 810 m
  • 970 m
  • 890 m
  • 870 m

Question 2

Question
A jet aeroplane descends with constant Mach number. Which of the following speed limits is most likely to be exceeded first?
Answer
  • Maximum Operational Mach Number
  • Maximum Operating Speed
  • Never Exceed Speed
  • High Speed Buffet Limit

Question 3

Question
The best rate of climb at a constant gross mass
Answer
  • decreases with increasing altitude since the thrust available decreases due to the lower air density.
  • increases with increasing altitude since the drag decreases due to the lower air density
  • increases with increasing altitude due to the higher true airspeed.
  • is independent of altitude

Question 4

Question
With a jet aeroplane the maximum climb angle can be flown at approximately:
Answer
  • 1.2 Vs
  • 1.1 Vs
  • The highest CL/CD ratio.
  • The highest CL/CD² ratio.

Question 5

Question
During climb with all engines, the altitude where the rate of climb reduces to 100 ft/min is called:
Answer
  • Thrust ceiling
  • Maximum transfer ceiling
  • Service ceiling
  • Absolute ceiling

Question 6

Question
The net flight path climb gradient after take-off compared to the gross climb gradient is:
Answer
  • larger.
  • equal.
  • depends on type of aircraft
  • smaller.

Question 7

Question
Which statement with respect to the step climb is correct ?
Answer
  • A step climb provides better economy than a cruise climb.
  • Performing a step climb based on economy can be limited by the 1.3-g altitude.
  • In principle a step climb is performed immediately after the aircraft has exceeded the optimum altitude.
  • A step climb may not be performed unless it is indicated in the filed flight plan.

Question 8

Question
The climb limited take-off mass can be increased by
Answer
  • selecting a lower VR.
  • a lower flap setting for take-off and selecting a higher V2.
  • selecting a lower V1.
  • selecting a lower V2.

Question 9

Question
The maximum mass for landing could be limited by
Answer
  • the climb requirements with all engines in the landing configuration but with gear up.
  • the climb requirements with one engine inoperative in the approach configuration.
  • the climb requirements with one engine inoperative in the landing configuration.
  • the climb requirements with all engines in the approach configuration.

Question 10

Question
The speed range between low speed buffet and high speed buffet
Answer
  • decreases with increasing mass and is independent of altitude.
  • is only limiting at low altitudes
  • increases with increasing mass
  • narrows with increasing mass and increasing altitude.

Question 11

Question
If there is a tail wind, the climb limited TOM will:
Answer
  • increase.
  • decrease.
  • increase in the flaps extended case.
  • not be affected.

Question 12

Question
According to JAR-OPS 1, which one of the following statements concerning the landing distance for a turbojet aeroplane is correct?
Answer
  • The landing distance is the distance from 35 ft above the surface of the runway to the full stop.
  • When determining the maximum allowable landing mass at destination, 60% of the available landing runway length should be taken into account.
  • Reverse thrust is one of the factors always taken into account when determining the landing distance required
  • Malfunctioning of an anti-skid system has no effect on the required runway length.

Question 13

Question
By what factor must the landing distance available (dry runway) for a turbojet powered aeroplane be multiplied to find the landing distance required? (planning phase for destination).
Answer
  • 115/100
  • 1.67
  • 60/115
  • 0.60

Question 14

Question
The landing field length required for jet aeroplanes at the alternate (wet condition) is the demonstrated landing distance plus
Answer
  • 92%
  • 43%
  • 70%
  • 67%

Question 15

Question
Two identical turbojet aeroplane (whose specific fuel consumptions are considered to be equal) are at holding speed at the same altitude. The mass of the first aircraft is 130 000 kg and its hourly fuel consumption is 4300 kg/h. The mass of the second aircraft is 115 000 kg and its hourly fuel consumption is:
Answer
  • 4044 kg/h.
  • 3365 kg/h.
  • 3578 kg/h.
  • 3804 kg/h.

Question 16

Question
A head wind will:
Answer
  • increase the rate of climb
  • shorten the time of climb.
  • increase the climb flight path angle.
  • increase the angle of climb

Question 17

Question
The take-off distance of an aircraft is 600m in standard atmosphere, no wind at 0 ft pressure-altitude. Using the following corrections: "± 20 m / 1 000 ft field elevation" "- 5 m / kt headwind" "+ 10 m / kt tail wind" "± 15 m / % runway slope" "± 5 m / °C deviation from standard temperature" The take-off distance from an airport at 1 000 ft elevation, temperature 17°C, QNH 1013,25 hPa, 1% upslope, 10 kt tail wind is:
Answer
  • 555 m
  • 685 m
  • 755 m
  • 715 m

Question 18

Question
"Maximum endurance"
Answer
  • is the same as maximum specific range with wind correction
  • can be flown in a steady climb only.
  • can be reached with the 'best rate of climb' speed in level flight.
  • is achieved in unaccelerated level flight with minimum fuel consumption.

Question 19

Question
VX is
Answer
  • the speed for best rate of climb
  • the speed for best specific range
  • the speed for best angle of flight path.
  • the speed for best angle of climb.

Question 20

Question
During take-off the third segment begins:
Answer
  • when acceleration to flap retraction speed is started.
  • when landing gear is fully retracted.
  • when acceleration starts from VLOF to V2.
  • when flap retraction is completed.
