Washington Dulles International to Dane County Rgnl/Truax Field IAD → MSN
593 nautical miles (683 statute miles) northwest on a straight line, true course 299°, about 309° magnetic at the departure end (variation 10W). At 120 knots that is 5 h 18 min at the quickest height in today's winds (4,500 ft, a 8-knot headwind), arriving about 2:32 am CDT (07:32 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: 2 flights in the DOT's last twelve reported months, the route's page.

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.
