10 When operating an unmanned airplane, the remote pilot should consider that the load factor on the wings may be increased any time
A. the CG is shifted rearward to the aft CG limit
"With aft loading and 'nose-down trim, the tail surfaces exert less down load, relieving the wing of that much wing loading and lift required to maintain altitude."
Typically in a fixed-wing aircraft, the center of gravity is slightly forward of the center of lift, so down force from the tail is needed to keep the aircraft level. In the illustration below, you can see the effect of the aircraft loading with respect to the location of the CG.
Note to multirotor pilots:
While the vast majority of UAS are multirotor aircraft, your Part 107 Remote Pilot Certificate appplies to fixed-wing UAS as well. So, even if you never fly a fixed-wing UAS, you still need to learn subjects specific to fixed-wing aircraft.
This is not the correct answer.
