William P Hobby Airport to Washington Dulles International HOU → IAD

1,042 nautical miles (1,200 statute miles) northeast on a straight line, true course 053°, about 050° magnetic at the departure end (variation 3E). At 120 knots that is 7 h 27 min at the quickest height in today's winds (30,000 ft, a 20-knot tailwind), arriving about 4:58 am EDT (08:58 UTC), after sunset at the destination. Right now HOU is VFR, wind from the southeast (140°) at 7 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: 8 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 10 forecast points nearest it (HOU, LCH, JAN, BHM, HSV, TYS, TRI, ROA, EKN, RIC). 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.
