What does gyropilot mean?
Gyropilot is a chiefly historical term for an automatic aircraft-guidance system that used gyroscopes to help maintain orientation and flight direction. In the early decades of powered aviation, such systems represented an important step toward the modern autopilot: they performed part of the work later handled by more sophisticated electronic and computerized controls. The word combines the Greek-derived combining form gyro-, associated with rotation and circular motion, with pilot, suggesting a mechanism that “pilots” the aircraft. In modern English, gyropilot survives mainly in historical, technical, and aviation-museum contexts; “autopilot” is normally preferred for a current system and may also cover devices based on technologies other than gyroscopes. In sentences, it denotes the equipment rather than a human aviator, even though its name includes pilot. The term is useful as a reminder that automated flight control developed through several experimental and practical stages before becoming the familiar system used in contemporary aircraft. Its use is uncommon, but it remains precise and informative when discussing early aviation technology or the historical evolution of automated guidance.
nounA chiefly historical gyroscope-based automatic pilot for an aircraft, designed to assist with maintaining orientation and flight direction.
- An early automatic pilot for an aircraft that used gyroscopes to help maintain stability, orientation, and direction.
"The experimental aircraft relied on a gyropilot to keep it stable during the flight."
"The gyropilot kept the aircraft level while the crew handled the remaining controls."
"A museum display explains how gyropilot systems were used in early aviation."
The plural is used when referring to multiple devices of this kind.
"The exhibition includes gyropilots from several early experimental aircraft."
A gyropilot literally let rotating instruments help steer an aircraft—an important step on the path to the modern autopilot.

Where does gyropilot come from?
Gyropilot combines the combining form gyro-, ultimately related to the Greek gŷros meaning “circle” or “round,” with pilot. The compound entered English in the early 20th century as engineers developed experimental systems for automatically stabilizing and guiding aircraft. Its meaning reflects an early stage in the development of the modern autopilot, particularly guidance systems that made use of gyroscopes.
How gyropilot is actually used
Chiefly historical and technical. In modern usage, autopilot is much more common and does not imply the specifically gyroscope-based design suggested by this term.
Easily confused with gyropilot
Autopilot is the usual modern, generic term for an aircraft's automatic flight-control system, whereas gyropilot usually refers specifically to early devices based on gyroscopes.
