Washington Dulles International to Philadelphia International IAD → PHL
117 nautical miles (135 statute miles) northeast on a straight line, true course 061°, about 071° magnetic at the departure end (variation 10W). At 120 knots that is 35 min at the quickest height in today's winds (34,000 ft, a 80-knot tailwind), arriving about 8:24 pm EDT (00:24 UTC), after sunset at the destination. Right now IAD is IFR, wind from the north (360°) at 7 knots; PHL is IFR, wind from the east-northeast (060°) at 9 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: 2,241 flights in the DOT's last twelve reported months, the route's page.

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 2 forecast points nearest it (RIC, ACY). 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.
