Norfolk International to St. Louis Lambert International ORF → STL
681 nautical miles (783 statute miles) west on a straight line, true course 284°, about 293° magnetic at the departure end (variation 9W). At 120 knots that is 6 h 15 min at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 3:28 am CDT (08:28 UTC), after sunset at the destination. 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: 36 flights in the DOT's last twelve reported months, the route's page.

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 8 forecast points nearest it (ORF, RIC, ROA, CRW, CVG, LOU, EVV, STL). 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.

STL has no terminal forecast; use the nearest airport that does.
Temporary flight restrictions on the line or within 25 nm of it
No temporary flight restriction on or near this route right now.
Daylight
Sunset at ORF 6:32 pm EDT (22:32 UTC), at STL 6:27 pm CDT (23:27 UTC) (civil twilight ends 6:54 pm CDT (23:54 UTC)). At 120 knots the arrival at STL is before sunrise there (7:07 am CDT (12:07 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.
