Definition
The collective set of ground-based and airborne systems, services, and tools that assist pilots in planning, conducting, and completing flights safely and efficiently. In the instrument flying context, this includes navigation aids, communication networks, weather information services, flight planning resources, air traffic control services, and onboard electronic systems that support situational awareness and decision-making.
Plain English
All the outside help a pilot uses to plan and fly a trip — things like navigation signals, weather updates, radios, charts, and air traffic control — combined with the equipment in the cockpit that makes use of them.
Context Anchor
Seen in the Instrument Flying Handbook when discussing the aircraft equipment that supports instrument flying and helps the pilot manage the aircraft, especially when outside visual references are limited.
Derivation
‘Support’ comes from the Latin supportare, meaning ‘to carry’ or ‘hold up.’ Flight support systems are the things that ‘hold up’ the pilot during a flight — they don’t fly the airplane, but the pilot relies on them throughout.
Why Pilots Care
These systems are required for all IFR operations and directly determine whether a pilot can maintain control and navigate accurately in instrument meteorological conditions.
Analogy
Think of flight support systems like the lights, mirrors, power steering, and dashboard in a car. The car can move without some of them, but they make safe operation much easier and sometimes are essential.
Intuition Check
Do not read “support” as ground support or customer support. Here, it means aircraft systems and equipment that help the pilot fly and manage the aircraft safely.
Example Sentence 1
Before departing on an IFR flight, the pilot used several flight support systems to check weather, file the flight plan, and review notams.
Example Sentence 2
Modern glass cockpits combine many flight support systems into a single integrated display.
