  1. Q1

    How is wind considered in the take-off performance data of the Aeroplane Operations Manuals?

    • AUnfactored headwind and tailwind components are used.
    • BNot more than 80% headwind and not less than 125% tailwind.
    • CSince take-offs with tailwind are not permitted, only headwinds are considered
    • DNot more than 50% of a headwind and not less than 150% of the tailwind.
    Show answer

    Correct answer: D. Not more than 50% of a headwind and not less than 150% of the tailwind.

  3. Q3

    The affect of a contaminated runway on the field limit mass :

    • ADecreased weight, increased V1, increased VR
    • BDecreased weight, same V1, increased VR.
    • CDecreased weight, same V1, same VR.
    • DDecreased weight, decreased V1, decreased VR.
    Show answer

    Correct answer: D. Decreased weight, decreased V1, decreased VR.

    • BIt increases slightly as the aircraft speed builds up.
    • CIt decreases slightly as the aircraft speed builds up.
    • DIt only varies with changes in mass.
    Show answer

    Correct answer: C. It decreases slightly as the aircraft speed builds up.

  5. Q5

    The required Take-off Distance (TOD) and the field length limited Take-off Mass (TOM) are different for the zero flap case and take-off position flap case. What is the result of flap setting in take-off position compared to zero flap position?

    • AIncreased TOD required and decreased field length limited TOM.
    • BIncreased TOD required and increased field length limited TOM.
    • CDecreased TOD required and decreased field length limited TOM.
    • DDecreased TOD required and increased field length limited TOM.
    Show answer

    Correct answer: D. Decreased TOD required and increased field length limited TOM.

  7. Q7

    The take-off run is defined as:

    • Adistance to V1 and then to stop, assuing the engine failure is recognised at V1
    • Bdistance from brake release to the point where the aircraft reaches V2
    • Cthe horizontal distance from the start of the take-off roll to a point equidistant between VLOF and 35 ft
    • Dthe distance to 35 ft with an engine failure at V1 or 1.15 times the all engine distance to 35 ft.
    Show answer

    Correct answer: C. the horizontal distance from the start of the take-off roll to a point equidistant between VLOF and 35 ft

  8. Q8

    The take-off distance available is:

    • Athe total runway length, without clearway even if this one exists.
    • Bthe length of the take-off run available plus the length of the clearway available.
    • Cthe runway length minus stopway.
    • Dthe runway length plus half of the clearway.
    Show answer

    Correct answer: B. the length of the take-off run available plus the length of the clearway available.

    • Bvaries with mass changes only.
    • Chas no change during take-off and climb.
    • Ddecreases while the aeroplane speed builds up.
    Show answer

    Correct answer: D. decreases while the aeroplane speed builds up.

    • CIt will decrease the take-off distance required.
    • DIt will increase the accelerate stop distance.
    Show answer

    Correct answer: C. It will decrease the take-off distance required.

  12. Q12

    The take-off distance of an aircraft is 800m in a standard atmosphere with no wind and 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% up-slope, 5 kt tail wind is:

    • A810 m

    • C890 m
    • D870 m
    Show answer

    Correct answer: B. 970 m
