CPL Flight Performance and Planning 2

Question 1

An aircraft's center of gravity (CG) is found to be aft of the aft limit. What is the primary concern?

Accepted Answer

Reduced longitudinal stability and possible loss of control

Answer

An aft CG reduces longitudinal static stability, making pitch control more difficult and potentially leading to an unrecoverable pitch-up.

Question 2

When calculating takeoff performance, which condition results in the longest ground roll?

Accepted Answer

High elevation, high temperature, tailwind

Answer

High elevation and high temperature reduce air density, lowering engine thrust and aerodynamic lift, while a tailwind increases groundspeed at liftoff, all combining to produce the longest ground roll.

Question 3

What is the definition of 'density altitude'?

Accepted Answer

Pressure altitude corrected for non-standard temperature

Answer

Density altitude is pressure altitude corrected for non-standard temperature, representing the air density the aircraft 'feels' for performance purposes.

Question 4

Under FAR Part 91, what fuel reserve is required for a VFR day flight to a destination 200 nm away at an aircraft cruise fuel burn of 15 GPH?

Accepted Answer

Enough fuel to fly to destination plus 30 minutes at cruise

Answer

FAR 91.151 requires VFR day flights to carry enough fuel to reach the destination plus at least 30 minutes of flight at cruise speed.

Question 5

A pilot uses a weight-and-balance chart and finds the loaded moment exceeds the maximum allowable moment. What action is required?

Accepted Answer

Redistribute or remove weight until within limits

Answer

If the loaded moment exceeds limits, weight must be redistributed or removed until both weight and CG are within the aircraft's approved envelope.
