Q:

The ground run distance is effected by the inverse of the density and directly proportional to square of the true airspeed.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: The ground run distance is effected by the inverse of the density and directly proportional to square of the true airspeed. The ground run distance is not effected by thrust. The ground run distance is not effected by thrust. The factors that affect ground run distance are: TAS, EAS and density.

Q:

The headwind only effects in the kinematic energy in the case of the airborne distance.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: The headwind only effects in the kinematic energy in the case of the airborne distance. The headwind is used to change the datum speed of the take-off. This headwind effects the ground run speed. For every 10% change in headwind, there is 20% decrease in the ground run distance.

Q:

What is the use of the headwind?

A) To change the datum height B) To change the datum temperature
C) To change the fuel ratio D) To change the pressure ratio
 
Answer & Explanation Answer: A) To change the datum height

Explanation: The headwind is used to change the datum speed of the take-off. This headwind effects the ground run speed. For every 10% change in headwind, there is 20% decrease in the ground run distance.

Q:

There are two atmospheric effects on the take-off distances.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: There are two atmospheric effects on the take-off distances. They are:
