How to Use the Weather Map Generator
Enter Route Information
Input your departure and destination airports using ICAO codes. Set your planned flight altitude and desired route corridor width for weather analysis.
Generate Weather Map
Click "Generate Weather Map" to calculate route weather conditions, flight rules, and wind components along your planned path.
Analyze Results
Review weather conditions at waypoints along your route. Use this information for preliminary planning, then verify with current weather sources before flight.
Pro Tips
- ✓Use wider corridors for long cross-country flights
- ✓Check multiple altitudes for better conditions
- ✓Always verify with current METARs before departure
- ✓Consider alternate routes for poor weather areas

Frequently Asked Questions
Enter your departure and destination airports using ICAO codes (e.g., KJFK, KORD). Set your flight altitude and route width to define the weather corridor along your path. The tool calculates weather conditions, visibility, and flight rules for waypoints along your route based on great circle navigation principles.
The map generator calculates visibility conditions, estimated flight rules (VFR, MVFR, IFR, LIFR), headwind/crosswind components, and weather trends along your route. It uses standard aviation weather criteria: VFR (>5 miles visibility, >3000ft ceiling), MVFR (3-5 miles, 1000-3000ft), IFR (1-3 miles, 500-1000ft), and LIFR (<1 mile, <500ft).
Weather conditions between airports are interpolated based on distance weighting from nearby reporting stations. While useful for planning, always verify current conditions with official weather sources, PIREPs, and radar before flight. The tool provides estimates for preliminary route assessment, not final go/no-go decisions.
For most flights, a 50-100 nautical mile corridor width provides good weather awareness without excessive data. Narrow routes (25-50nm) work for short flights with good weather, while wide corridors (100-200nm) help identify weather systems and alternate routing options for long cross-country flights.
Green indicates VFR conditions suitable for visual flight rules. Yellow shows MVFR (marginal VFR) requiring extra caution. Red indicates IFR conditions requiring instrument flight rules. Purple shows LIFR (low IFR) with very poor conditions. Always check current METARs and TAFs for official flight rules determinations.
Yes, the tool works with any valid ICAO airport codes worldwide. Enter international airports using their four-letter ICAO codes (e.g., EGLL for London Heathrow, RJTT for Tokyo Haneda). Weather calculations use the same international standards, though you should verify local weather minimums and regulations for international operations.
