autogyroer
An autogyroer is an individual who pilots, operates, or maintains an autogyro, a rotorcraft that uses an unpowered, freely turning rotor for lift and a separate engine-driven propeller for thrust. Autogyroers are often pilots with specialized training to handle the unique flight characteristics of rotary-wing aircraft that are neither true helicopters nor fixed-wing airplanes. They must be proficient in take‑off, landing, and low‑speed handling, as the rotor gains lift as air moves up through the device, requiring careful speed management to avoid stalling the rotor or "dive" during descent.
In addition to piloting duties, autogyroers may be involved in aircraft maintenance, inspecting rotor blades, gearbox
