Raleigh-Durham International to Dane County Rgnl/Truax Field RDU → MSN
654 nautical miles (753 statute miles) northwest on a straight line, true course 315°, about 324° magnetic at the departure end (variation 9W). At 120 knots that is 6 h at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 3:08 am CDT (08:08 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: 53 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 7 forecast points nearest it (RDU, ROA, CRW, CMH, FWA, JOT, DBQ). 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.

Daylight
Sunset at RDU 6:43 pm EDT (22:43 UTC), at MSN 6:19 pm CDT (23:19 UTC) (civil twilight ends 6:48 pm CDT (23:48 UTC)). At 120 knots the arrival at MSN 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.
