helicopter
Let an agent explain how helicopters work and their types, describe civil uses such as emergency helicopters, support aviation safety and regulation questions, and provide sourced data on specific models.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain how helicopters work and their types, describe civil uses such as emergency helicopters, support aviation safety and regulation questions, and provide sourced data on specific models.
A rotorcraft that gains lift and thrust from one or more powered horizontal rotors, able to take off and land vertically, hover and fly in any direction, used for transport, emergency medical services, search and rescue, firefighting, policing, offshore work, agriculture, news and military roles; helicopters range from light piston machines to heavy-lift types and are certified and operated under aviation regulations.
What it is for: Vertical take-off rotary-wing flight.
It can be explain how helicopters fly; describe types and uses; explain regulation, licensing and safety; provide data on specific models.
Distinguishing features
Powered rotor lift
Hover capability
Complex controls
Regulated aviation
What it looks like
An aircraft with a large main rotor and usually a tail rotor, or twin rotors.
How it is recognised
Powered horizontal rotor
Vertical take-off and hover
Autogyros have unpowered rotors; tiltrotors convert to aeroplane flight
