Aviation Glossary
10A comprehensive glossary of aviation terms, acronyms, and technical jargon explained in plain language.
Automatic Dependent Surveillance-Broadcast
Surveillance technology where aircraft automatically broadcast GPS-derived position, altitude, speed, and identity to ground stations and other aircraft.
Navigation & SystemsAutopilot
System that automatically controls an aircraft's flight path without continuous manual input from the pilot.
Navigation & SystemsFlight Management System
Onboard computer system that automates in-flight navigation, performance calculations, and fuel management across all phases of flight.
Navigation & SystemsFly-by-Wire
Electronic flight control system that replaces traditional mechanical linkages between the pilot's controls and the aircraft's control surfaces.
Navigation & SystemsGlass Cockpit
Flight deck featuring large multifunction electronic displays replacing the traditional array of analog round-dial instruments.
Navigation & SystemsHead-Up Display
Transparent display that projects critical flight information onto a combiner glass in the pilot's forward line of sight, allowing simultaneous instrument monitoring and outside visual reference.
Navigation & SystemsInstrument Landing System
Ground-based radio navigation system providing precise lateral and vertical guidance to aircraft during approach and landing in low-visibility conditions.
Navigation & SystemsTraffic Collision Avoidance System
Airborne collision avoidance system that independently monitors surrounding air traffic and issues advisories to pilots when a collision risk is detected.
Navigation & SystemsTransponder
Airborne radio transmitter-receiver that automatically replies to ground radar interrogations, broadcasting the aircraft's identity and altitude.
Navigation & SystemsWeather Radar
Onboard radar system that detects precipitation, storm cells, and turbulence along the flight path, enabling pilots to navigate around hazardous weather.
