What is the advantage of balancing V1, even in the event of a climb limited take-off?

A: The climb limited take-off mass is the highest.
B: The take-off distance required with one engine out at V1 is the shortest.
C: The accelerate stop distance required is the shortest.
D: The safety margin with respect to the runway length is greatest.

 

 

 

 

 

 

 

 

Answer: D

What is the result of a large take off flap setting compared to a small take off flap setting on required Take-off Distance (TOD) and the field length limited Take-off Mass (TOM)?

A: Increased TOD required and decreased field length limited TOM.
B: Decreased TOD required and increased field length limited TOM.
C: Increased TOD required and increased field length limited TOM.
D: Decreased TOD required and decreased field length limited TOM.

 

 

 

 

 

 

 

 

Answer: B

Which statement, in relation to the climb limited take-off mass of a jet aeroplane, is correct?

A: 50% of a head wind is taken into account when determining the climb limited take-off mass.
B: The climb limited take-off mass is determined at the speed for best rate of climb.
C: The climb limited take-off mass decreases with increasing OAT.
D: On high elevation airports equipped with long runways the aeroplane will always be climb limited.

 

 

 

 

 

 

 

 

Answer: C

The take-off run is

A: 1.15 times the distance from the point of brake release to the point at which VLOF is reached assuming a failure of the critical engine at V1.
B: 1.5 times the distance from the point of brake release to a point equidistant between the point at which VLOF is reached and the point at which the aeroplane attains a height of 35 ft above the runway with all engines operative.
C: the horizontal distance along the take-off path from the start of the take-off to a point equidistant between the point at which VLOF is reached and the point at which the aeroplane is 35 ft above the take-off surface.
D: the distance of the point of brake release to a point equidistant between the point at which VLOF is reached and the point at which the aeroplane attains a height of 50 ft above the runway assuming a failure of the critical engine at V1.

 

 

 

 

 

 

 

 

Answer: C

Which statement is correct for a descent without engine thrust at maximum lift to drag ratio speed?

A: A tailwind component increases the ground distance.
B: A headwind component increases the ground distance.
C: A tailwind component increases fuel and time to descent.
D: A tailwind component increases the time in the descent

 

 

 

 

 

 

 

 

Answer: A

With zero wind, the angle of attack for maximum range for an aeroplane with turbojet engines is:

A: equal to the angle of attack corresponding to maximum endurance
B: lower than the angle of attack corresponding to maximum endurance
C: equal to the angle of attack corresponding to zero induced drag.
D: equal to the angle of attack corresponding to maximum lift to drag ratio.

 

 

 

 

 

 

 

 

Answer: B

Other factors remaining constant and not limiting, how does increasing pressure altitude affect allowable take-off mass?

A: There is no effect on allowable take-off mass.
B: Allowable take-off mass increases.
C: Allowable take-off mass decreases.
D: Allowable take-off mass remains uninfluenced up to 5000 ft pressure altitude.

 

 

 

 

 

 

 

 

Answer: C

In unaccelerated climb

A: lift is greater than the gross weight.
B: thrust equals drag plus the downhill component of the gross weight in the flight path direction.
C: lift equals weight plus the vertical component of the drag.
D: thrust equals drag plus the uphill component of the gross weight in the flight path direction.
