QUESTIONAfter loading a payload, a remote pilot determines that the center of gravity (CG) is outside the allowable limits. What does the Remote Pilot study guide say must be done before flight is attempted?

  1. ARelocate or shed some weight
  2. BTrim the aircraft nose-down to compensate
  3. CAdd ballast until the aircraft is at maximum gross weight
Show the answer and explanation

Correct answer: A. Relocate or shed some weight

  • A — correct The guide states that if the CG is not within allowable limits after loading, it will be necessary to relocate or shed some weight before flight is attempted.
  • B — incorrect The guide does not offer trim as a remedy; the CG must be brought within limits by moving or removing weight.
  • C — incorrect Adding weight to reach maximum gross weight is not the described remedy and could worsen performance.

BACKGROUND

Limits for the location of the center of gravity (CG) may be established by the manufacturer. Because the CG depends on weight distribution, shifting or expending load items can move it. The Remote Pilot study guide says the remote pilot in command should determine how the CG will shift and its effects on the aircraft. If the CG is not within the allowable limits after loading, or would not remain within limits during flight, it is necessary to relocate or shed some weight before flight is attempted.

STUDY TIP

The fix for an out-of-limits CG is always to move or remove weight, not to fly and compensate.

KEY POINTS

  • Manufacturer may set CG limits.
  • Check that the CG stays within limits for the whole flight.
  • If not, relocate or shed weight before flight.
