Definition
The combined process of getting ready to fly, consisting of two phases: preparation (planning the flight, reviewing weather, performance, weight and balance, fuel, route, and personal readiness before arriving at the aircraft) and preflight (the physical inspection of the airplane and its systems immediately before engine start to confirm it is airworthy and ready for the intended flight).
Plain English
Everything a pilot does to get ready before flying — first the planning and paperwork side, then the hands-on walk-around and checks at the airplane.
Context Anchor
Encountered before every flight, especially before engine start, during flight planning, aircraft document checks, and the walk-around inspection.
Derivation
‘Preparation’ comes from the Latin praeparare, ‘to make ready beforehand.’ ‘Preflight’ simply joins ‘pre-’ (before) with ‘flight.’ Together the phrase emphasises that readiness happens in two stages — the thinking-and-planning stage, and the looking-and-checking stage at the airplane itself.
Why Pilots Care
Directly determines whether the aircraft is airworthy and the pilot is ready, reducing the chance of in-flight problems or regulatory violations.
Grounding Statement
Before a flight begins, the pilot uses this phase to decide: is this airplane, on this route, with this pilot, ready to go?
Intuition Check
Preparation and Preflight does not mean only walking around the airplane. It includes both planning the flight and checking the airplane before flying.
Example Sentence 1
Her preparation and preflight took nearly an hour because the cross-country route required careful weather review and a thorough walk-around.
Example Sentence 2
Thorough preparation and preflight helps catch issues before takeoff.
