St. Louis Lambert International to Pittsburgh International STL → PIT

480 nautical miles (552 statute miles) east on a straight line, true course 074°, about 075° magnetic at the departure end (variation 1W). At 120 knots that is 3 h 16 min at the quickest height in today's winds (39,000 ft, a 27-knot tailwind), arriving about 12:55 am EDT (04:55 UTC), after sunset at the destination. Right now STL is VFR, wind from the southeast (130°) at 7 knots; PIT is marginal VFR, wind from the east-northeast (060°) at 4 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: 1,025 flights in the DOT's last twelve reported months, the route's page.

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

SIGMET 3E: thunderstorms (a convective SIGMET) up to 31,000 ft, moving from the west at 15 knots, until 9:55 pm CDT (02:55 UTC). Over the route from 392 to 411 nm out.

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 7 forecast points nearest it (STL, SPI, EVV, IND, CVG, CMH, AGC). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th 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.
