Types of drone
Drones, or remotely piloted aircraft (RPA), are classified into the following types and size categories.
This type of drone has more than one power-driven engine (rotor) that rotate or turn vertically. It takes off, lands, flies and hovers like a traditional 'single rotor' helicopter but has more than one rotor.
This type of drone usually has one power-driven engine (rotor) and looks a bit like a traditional helicopter. It usually also has another rotor on the tail or end of the aircraft.
This type of drone looks and flies like a regular plane - it has fixed wings. It also takes off and lands horizontally and usually can't hover.
This type of drone can take off and land vertically (straight up and down) like a helicopter, but can then more into forward flight like a traditional plane.
This type of drone is engine powered and is 'lighter than air' - it can be filled with a buoyant gas and usually 'floats' in the air. A blimp is a good example of an airship.
These represent simplified 'plain-English' definitions. You can find the official technical definitions for each RPA in the locations below:
