Part 107 test practice question: Loading and Performance

Loading and PerformanceDifficulty 2/5

Mounting a heavy camera far forward on an sUAS, beyond the manufacturer's CG range, most likely results in:

  1. AHigher maximum speed
  2. BImproved stability and longer endurance
  3. CReduced stability and controllability
  4. DNo effect if total weight is within limits
Show answer and rationale

Correct: C. A CG outside limits shifts the aircraft away from its designed balance point, degrading stability and control authority even if total weight is legal.

  • B — Off-limit CG does not improve stability.
  • D — Weight and balance are separate limits; both must be met.
  • A — Speed is not improved by imbalance.
