An increase in the takeoff speed V1, VR and V2 results in an increase in the field length required 3. For a fixed runway length, the field length limit weight increase with an increase in V2 4. The tire speed limits and brake energy limits may become limiting at the higher takeoff speeds. 1 & 2 & 3 only. 1 & 2 & 4 only. 2 & 4 only. 2 & 3 & 4 only.

Which statements are correct concern thrust derate: 1. Use of derates is permitted on contaminated runway, anti-skid inoperative, landing gear extended. 2. It is necessary to publish specific performance data tailored to that derate to flight crew 3. One of the advantage of using derated thrust is when maximum take-off weight is VMCG limited at full take-off thrust rating 4. The Vmcg speed is independent of the levels of take-off thrust derate. 2 & 3 & 4. 1 & 2 & 3. 1 & 3 only. 2 & 3 only.

Which of the following statements are correct concerning reduced thrust takeoff using assumed temperature method: 1. Reduced thrust takeoff using assumed temperature method gives an aircraft performance equal to performance at the assumed temperature 2. If the assumed temperature is lower than flat rated temperature, this can still achieve thrust reduction 3. Reduced thrust may not be used on wet runway takeoff. 1 & 2 only. None of the above. 1 & 3 only. All of the above.

A range of V1/VR values become available for take-off when: the WAT limited, field length limited and maximum authorized weights are coincident authorized weight. the field length limited and WAT limited weights are coincident, and exceeded by the maximum. the actual take-off weight is exceeded by both the WAT and field length limited weights. the field length limited weight is exceeded by both the WAT limited and maximum authorized weights.

For a given weight and takeoff weight is not field length limit, with a low V1 gives: 1. Long ASD required 2. Short TOD required 3. Short ASD required 4. Long TOD required. 3 & 4. 1 & 2. 1 & 4. 2 & 3.

When the airplane takeoff weight is not field length limited, the advantages of selecting a high V1 are: 1. Required less take off distance for a continued takeoff 2. Better vertical clearance above an obstacle 3. More stopping margin for the RTO 4. More margin for climb limit. 1 & 3. 1 & 2 & 3. 1 & 2 & 3 & 4. 1 & 2.

The gross climb gradients of the takeoff flight path for a given weight is a function of: 1. Airport pressure altitude 2. Airport temperature 3. Runway slope 4. Runway length. 1 & 2. 2 only. 1 & 2 & 3 & 4. 1 & 2 & 3.

Which of the following is true for declared distance for a given runway?. EDA = TORA and balance field exits. LDA > EDA. 1.25 deg < Max slope of the clearway plane. EDA = Usable runway + stopway.

Higher V2 uses (i) takeoff distance, a (ii) in the distance to an obstacle resulting in a (iii) climb gradient required. (i) Less (ii) Decrease (iii) Decreased. (i) Increased (ii) Decrease (iii) Increased. (i) Increased (ii) Increase (iii) Decreased. (i) Less (ii) Increase (iii) Increased.

Which of the following is true regarding use of reduced thrust takeoff? 1. If the assumed temperature is lower than flat rated temperature, then there will be no reduction in thrust. 2. Can be used if OAT is less than the assumed temperature 3. Reduced thrust may not be used on wet runway takeoff 4.
