St. Louis Lambert International to Key West International STL → EYW

958 nautical miles (1,102 statute miles) southeast on a straight line, true course 150°, about 151° magnetic at the departure end (variation 1W). At 120 knots that is 6 h 04 min at the quickest height in today's winds (34,000 ft, a 38-knot tailwind), arriving about 11:17 pm EDT (03:17 UTC), after sunset at the destination. Right now STL is VFR, wind from the west-southwest (240°) at 15 knots, gusting to 20; EYW is VFR, wind from the north-northeast (020°) at 10 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 2 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.

Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of

No SIGMET or AIRMET covers any part of this route right now.

Turbulence No turbulence warning in force along the route. 3 pilot reports of turbulence near the line in the last three hours: light to moderate turbulence, at 26,000 ft, 31 nm southwest, 2:18 pm CDT (19:18 UTC); light chop turbulence, at 28,000 ft, 46 nm southwest, 2:24 pm CDT (19:24 UTC). The government's turbulence forecast map ↗

Icing No icing warning in force along the route. No pilot has reported icing near the line in the last three hours. The freezing level is about 15,500 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from STL.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

C25B at 26,000 ft, 31 nm southwest, 2:18 pm CDT (19:18 UTC): light to moderate turbulence, remarks: zkc fdc xj. At the departure end, 31 nm southwest of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 9 forecast points nearest it (STL, CGI, BNA, HSV, BHM, MGM, TLH, PIE, EYW). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 18:00 UTC; valid on the 13th at 00:00 UTC for use 20:00 to 03:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.

Sunset at STL 6:27 pm CDT (23:27 UTC), at EYW 7:03 pm EDT (23:03 UTC) (civil twilight ends 7:26 pm EDT (23:26 UTC)). At 120 knots the arrival at EYW is after sunset there (7:03 pm EDT (23:03 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
