Most restrictions have restrictions on the use of UAVs which have greatly limited their use in controlled airspace; UAVs have mostly been limited to military and hobbyist use. In the United States, use of UAVs is very limited in controlled airspace (generally, above 400 ft / 122m and away from airports) and the FAA prohibits nearly all commercial use. Once regulations are made to allow expanded use of UAVs in controlled airspace, there is expected to be a large surge of UAVs in use and, consequently, high demand for pilots / operators of these aircraft.

The general concept of an airplane pilot can be applied to human spaceflight, as well. The spacecraft pilot is the astronaut who directly controls the operation of a spacecraft. This term derives directly from the usage of the word “pilot” in aviation, where it is synonymous with “aviator”.
