Definition
Information provided by air traffic controllers to assist pilots in avoiding hazardous weather, including the location, intensity, and movement of significant weather such as thunderstorms, turbulence, icing, and precipitation, to the extent permitted by controller workload and the limitations of available radar and weather data.
Plain English
Help from ATC in steering around bad weather. Controllers share what they can see about storms, rough air, or icing so the pilot can decide how to avoid it, but only as their workload and equipment allow.
Context Anchor
Used when a pilot is talking with air traffic control and needs help because weather is affecting the flight path, arrival, departure, or airport area.
Derivation
Assistance comes from a Latin root meaning “to stand by” or “to help.” That fits the aviation meaning: the controller stands by with useful weather information and coordination, but the pilot still flies the aircraft and makes the final decision.
Why Pilots Care
Ensures pilots receive accurate weather details that influence go or no-go decisions and route adjustments.
Intuition Check
Weather Assistance does not mean air traffic control becomes your weather planner or guarantees a safe route. It means the controller helps with available weather information while the pilot remains responsible for the flight.
Example Sentence 1
The pilot requested weather assistance from Center to find a path around a line of building thunderstorms ahead.
Example Sentence 2
While flying, the pilot received weather assistance to assess changing conditions ahead.
