Definition
The process of gathering, evaluating, and interpreting weather information — including reports, forecasts, charts, and observed conditions — to determine how current and expected weather will affect a planned flight.
Plain English
Looking at the weather picture as a whole and working out what it means for the flight you are about to make.
Context Anchor
Used during preflight planning, scenario-based training, and any go-or-wait decision where weather could affect the flight.
Derivation
From Greek 'analusis' meaning 'a breaking up' — taking something complex apart to understand it. In aviation, the pilot breaks the weather picture into its parts (winds, ceilings, visibility, fronts, icing, turbulence) and then reassembles it into a clear understanding of what the flight will encounter.
Why Pilots Care
Thorough weather analysis helps avoid hazardous conditions that contribute to many weather-related accidents.
Grounding Statement
Weather analysis turns raw weather information into a practical flight decision: go, wait, change the plan, or cancel.
Intuition Check
Weather analysis does not mean simply checking the weather. It means deciding how the weather affects this specific flight.
Example Sentence 1
During preflight, the instructor asked the student to walk through her weather analysis before deciding whether to launch.
Example Sentence 2
During the lesson the instructor had the student explain their weather analysis for the planned route.
