Environmental
Unmanned aircraft are more susceptible to adverse weather than their manned counterparts due to their relative size. Although turbulence occurs in both large and small planes, it is typically worse in smaller planes because they weigh less, and thus more likely to be moved around. Winds at altitude are usually stronger than what is felt on the ground. It is crucial to obtain a weather briefing or forecast before each flight.

*Operating near environmental limits, such as density altitude and surface winds, may require carrying less fuel or a reduction in payload capacity.
Density altitude takes into account the fact that as altitude increases, the air becomes less dense, which affects an aircraft's lift, engine performance, and overall aerodynamic behavior. Temperature also plays a role in air density; warmer air is less dense than cooler air at the same pressure. This means that at a specific altitude, if the temperature is significantly higher than standard, the density altitude will be higher than the actual physical altitude, impacting aircraft performance as if it were flying at a higher elevation.
Prohibited Maneuvers
