Total range is dependent on both fuel available and specific range. When range and economy of operation are the principle goals, the remote pilot must ensure that the sUAS is operated at the recommended long-range cruise condition. By this procedure, the sUAS will be capable of its maximum design-operating radius, or can achieve lesser flight distances with a maximum of fuel reserve at the destination.

The manufacturer is the best source of performance data and information, if available.

Unmanned aircraft performance can be decreased due to an increase in load factor when the aircraft is operated in maneuvers other than straight-and-level flight.

When the angle of attack is increased to between 18 and 20 degrees (critical angle of attack) on most airfoils, the airstream can no longer follow the upper curvature of the wing because of the excessive change in direction. The airfoil will stall if the critical angle of attack is exceeded. The airspeed at which stall occurs will be determined by weight and load factor, but the stall angle of attack is the same.

The remote PIC is responsible for ensuring that every flight can be accomplished safely, does not pose an undue hazard, and does not increase the likelihood of a loss of positive control.
