Ronald Reagan Washington Ntl Airport to Capital Region International DCA → LAN
416 nautical miles (479 statute miles) northwest on a straight line, true course 307°, about 318° magnetic at the departure end (variation 11W). At 120 knots that is 3 h 33 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 1:27 am EDT (05:27 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: 558 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 5 forecast points nearest it (RIC, PSB, AGC, CLE, MKG). 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.
