Loading & Performance

5 free sample questions of the 25 in this topic. The full set is in the app.

1. Question 1

   Adding payload outside a drone's center of gravity (CG) envelope will most likely:

   • A.Improve stability
   • B.Decrease battery consumption
   • C.Cause unstable handling and possibly loss of control
   • D.Have no effect
   Show answer & explanation

   Answer: C. Cause unstable handling and possibly loss of control

   Operating outside CG limits degrades handling, may cause unexpected pitch/roll, and can exceed motor control authority.

2. Question 2

   As ambient temperature increases (pressure and altitude constant), what happens to aircraft performance?

   • A.Performance improves
   • B.Performance degrades (higher density altitude)
   • C.Unchanged
   • D.Better in warmer air, worse in cold air
   Show answer & explanation

   Answer: B. Performance degrades (higher density altitude)

   Higher temperature reduces air density, raising density altitude and reducing thrust/lift.

3. Question 3

   Load factor in a sUAS during a steep, fast turn:

   • A.Decreases — the drone is banked
   • B.Remains 1 G regardless of turn
   • C.Increases proportional to the bank angle
   • D.Is only relevant for fixed-wing aircraft
   Show answer & explanation

   Answer: C. Increases proportional to the bank angle

   Load factor increases with bank angle (e.g., 60° bank = 2 G). Multirotor drones also experience increased thrust demand and current draw.

4. Question 4

   Cold weather's main effect on LiPo battery performance is:

   • A.Batteries produce more power
   • B.Reduced capacity and voltage under load
   • C.No effect
   • D.Faster charging times
   Show answer & explanation

   Answer: B. Reduced capacity and voltage under load

   Cold lithium cells have higher internal resistance — reduced capacity and greater voltage sag, reducing flight time.

5. Question 5

   A remote pilot planning to fly at a high-altitude airport (6,500 ft MSL) on a hot day should expect:

   • A.Shorter takeoff and longer flight times
   • B.Reduced thrust, shorter flight times, and reduced payload capacity
   • C.No difference in performance
   • D.Improved battery performance
   Show answer & explanation

   Answer: B. Reduced thrust, shorter flight times, and reduced payload capacity

   High density altitude reduces available thrust and lift — plan for less payload and shorter hover/flight times.
