Terminal Aerodrome Weather Intelligence
Live METAR & TAF Aviation Weather Decoder
Translate raw ICAO METAR surface observations and TAF terminal forecasts into clear operational flight rules, cloud ceiling tiers, density altitude benchmarks, and barometric altimeter conversions.
Aviation Weather Fundamentals
- Decodes real-time METAR and TAF aerodrome weather telegrams into structured flight rules (VFR, MVFR, IFR, LIFR).
- Computes density altitude, dew point spread, and crosswind potential from runway heading vectors.
- Features instant presets for 30+ world hub airports with raw string lookup and live translation.

FAA & ICAO Flight Categories Classification
VFR Visual Flight Rules
Ceiling greater than 3,000 ft AGL and visibility greater than 5 statute miles.
Unrestricted visual conditions; suitable for all general and commercial traffic without instrument procedures. MVFR Marginal VFR
Ceiling 1,000 to 3,000 ft AGL and/or visibility 3 to 5 statute miles.
Reduced visual margins; caution advised for visual approaches, visual terrain clearance monitoring required. IFR Instrument Flight Rules
Ceiling 500 to 1,000 ft AGL and/or visibility 1 to 3 statute miles.
Instrument approach procedures mandatory (ILS, RNP, RNAV). Increased separation buffers in terminal areas. LIFR Low Instrument Flight Rules
Ceiling below 500 ft AGL and/or visibility below 1 statute mile.
Severe restriction. Cat II / Cat III ILS autoland required. Ground stop and flow management hold risk.
