Air density, air stability, and fronts
- Wind and currents can affect sUAS performance and maneuverability during all phases of flight. You have to be careful when flying at low altitudes in confined areas, near buildings, or other natural obstructions. Consider this, any obstruction on the ground, such as a building can create wind gusts that can greatly damage your aircraft, or hurt people or property. It is your responsibility as the remote pilot in command to take into account all of the obstructions that you may encounter in your flight. As you probably know, different surfaces radiate heat in different amounts. The result is an uneven heating of the air that can create small areas of local circulation called convective currents. These convective currents can cause bumpy, turbulent air that can dramatically affect your ability to control the aircraft at lower altitudes. Atmospheric stability describes a state in which air resists vertical displacement. In an unstable atmosphere, small vertical air movements tend to…
