4.10. Minimum team size for missions

Pilot task overload can be avoided by having the right number of support staff. Visual observers can assist the pilot in command or people manipulating controls to see and avoid other air traffic or objects aloft or on the ground. They can also be helpful in keeping the takeoff and landing areas clear of people or animals.

Support for the pilot is particularly important if the pilot needs to concentrate on controlling the payload, be it cameras, sensors or agricultural chemicals.
