Perot Fld/Fort Worth Alliance Airport to St. Louis Lambert International AFW → STL

483 nautical miles (556 statute miles) northeast on a straight line, true course 042°, about 038° magnetic at the departure end (variation 4E). At 120 knots that is 3 h 13 min at the quickest height in today's winds (3,500 ft, a 30-knot tailwind), arriving about 12:17 pm CDT (17:17 UTC). Right now AFW is marginal VFR, wind from the south (170°) at 11 knots; STL is VFR, wind from the southwest (220°) at 12 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: 685 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

AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Near the route, 355 nm along the route.

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 AFW.

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

A321 at 34,000 ft, 38 nm southwest, 8:39 am CDT (13:39 UTC): no turbulence, remarks: ZFW94. At the departure end, 38 nm southwest of the line.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 5 forecast points nearest it (DAL, FSM, SGF, COU, STL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
