Definition
The arrangement of an aircraft's movable components — such as flaps, landing gear, slats, and spoilers — set to suit a particular phase of flight.
Plain English
How the aircraft is set up at any given moment: gear up or down, flaps in or out, and so on, depending on what part of the flight you are in.
Context Anchor
Seen in aircraft operating procedures, checklists, performance charts, and training discussions about takeoff, climb, cruise, approach, and landing.
Derivation
From Latin 'configurare,' meaning 'to shape together.' A flight configuration is literally how the aircraft is shaped at that moment — what's extended, retracted, or set — to match the phase of flight.
Why Pilots Care
Selecting the correct flight configuration keeps the aircraft within safe speed and performance limits; the wrong setup can cause excessive drag, stalls, or unstable handling.
Intuition Check
Do not read flight configuration as the flight route or the flight plan. Here, it means the aircraft’s physical setup for that part of the flight.
Example Sentence 1
Before crossing the final approach fix, the pilot established the aircraft in the landing configuration with gear down and full flaps.
Example Sentence 2
On final approach the crew completed the landing flight configuration with gear down and full flaps.
