Watertown International to Washington Dulles International ART → IAD
310 nautical miles (356 statute miles) south on a straight line, true course 193°, about 205° magnetic at the departure end (variation 12W). At 120 knots that is 2 h 48 min at the quickest height in today's winds (10,500 ft, a 9-knot headwind), arriving about 12:24 am EDT (04:24 UTC), after sunset at the destination. Right now ART is VFR, wind from the south-southeast (160°) at 3 knots; IAD is IFR, wind from the north (350°) at 6 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 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.
