The centre of gravity is located aft. How does this affect take-off performance and climb gradient?
  • A
    Take-off ground roll distance is reduced and climb gradient is higher.
  • B
    Take-off ground roll distance is increased and climb gradient is higher.
  • C
    Take-off ground roll distance is reduced and climb gradient is lower.
  • D
    Take-off ground roll distance is increased and climb gradient is lower.

Refer to figures.
The relationship between your aircraft's performance and CG location is simple: by moving your CG forward and aft, you change the amount of tail down force and lift you need for stable flight.

When you create more lift, (you increase the angle of attack and climb gradient will be higher) threfore you create more induced drag, take-off ground roll distance is reduced and your performance goes down.
