Meaning and Definition
The integrated computer systems in an aircraft cockpit that automate navigation, flight planning, fuel management, and performance optimization during a flight.
In broader usage, can refer to any integrated suite of software and hardware (often called FMS) responsible for managing various aspects of vehicle or mission trajectory, navigation, and performance, applicable in aviation, aerospace, and sometimes in analogous ground or maritime transport contexts.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling follows national conventions within component words (e.g., 'manoeuvre' vs. 'maneuver' in related documentation).
Connotations
Identical technical connotations in both varieties.
Frequency
Frequency is tied to the aviation industry, which uses standardized international terminology. Equally common in UK and US aviation contexts.

- Misspelling as 'flight managment systems' (missing 'e').
FAQ
Frequently Asked Questions
No, but they are closely integrated. An FMS is the computer that calculates the route, speed, and altitude. The autopilot is the system that physically moves the aircraft's controls to follow the FMS's instructions.
Modern small general aviation aircraft often have simplified versions, sometimes called GPS navigators or avionics suites with FMS-like functions. Full, complex FMS are typical in commercial airliners and business jets.
Aircraft are designed with redundancy (multiple systems). In case of a total FMS failure, pilots can navigate using primary flight instruments, radio aids, and manual calculations, following backup procedures.
Not directly. They guide the plane to the final approach. A separate system called the 'autoland' or 'autothrottle' works with the FMS and autopilot to perform automatic landings, but only at airports equipped for it and in suitable weather.

Learning
Memory Aids
Mnemonic
Think of a FLIGHT that needs MANAGing; the SYSTEM that does it is the Flight Management System. Pilots 'manage' the flight, but the FMS helps them do it.
Conceptual Metaphor
THE AIRCRAFT'S BRAIN / AUTOPILOT. The system is conceptualized as an intelligent entity that calculates, plans, and executes, reducing pilot workload.
