Profiles are saved on this device and control status colors. Runways below Min Length or Min Width are marked WARN.
Airport and runway data comes from the FAA airport database for U.S. airports when available. Some military, chart-verified, and non-U.S. fields use the best available fallback data. Runway headings should be close, but always verify with current official publications.
XW: wind x sin(angle) HW/TW: wind x cos(angle) Rounding: nearest knot; .5 rounds up. Gust factor is considered.
Runway Ranking: BEST has the lowest score. Lower XW is better, TW is penalized heavily, and HW gets a small credit. Below Min Length/Width ranks after runways that meet limits. CAUT starts at 90% of XW/TW limit; WARN is over limit. Ties favor longer, then wider runways.
