An increase in load factor on an unmanned aircraft will cause it to:

An increase in load factor affects the stalling characteristics of an aircraft by altering the lift required to maintain level flight. The load factor is essentially the ratio of the actual lift of the aircraft to the weight of the aircraft and increases during maneuvers such as turns or climbing. When the load factor increases, the wings must produce more lift to counteract the added load.

This increase in lift demand raises the stalling speed because the aircraft must fly faster to generate the necessary lift to counteract the increased load factor. As a result, a higher airspeed is needed to maintain controlled flight without stalling. Therefore, stalling at a higher airspeed due to a higher load factor is a fundamental aerodynamic principle that pilots need to understand, particularly in the context of unmanned aircraft systems.

In contrast, the other options do not accurately reflect the impact of increased load factor on the flight characteristics of an unmanned aircraft. For example, while more power may be required for other operations, it is not a direct consequence of load factor in the context described in the question. Similarly, changes in altitude and rate of descent do not typically increase simply due to load factor alone. Understanding the relationship between load factor and stall speed is crucial for safe operation in
