Washington Dulles International to Ogdensburg International IAD → OGS

356 nautical miles (409 statute miles) north on a straight line, true course 014°, about 024° magnetic at the departure end (variation 10W). At 120 knots that is 1 h 51 min at the quickest height in today's winds (34,000 ft, a 73-knot tailwind), arriving about 11:35 pm EDT (03:35 UTC), after sunset at the destination. Right now IAD is IFR, wind from the north (350°) at 6 knots; OGS is VFR, wind from the south-southwest (200°) at 8 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: 439 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 3 forecast points nearest it (PSB, AVP, SYR). 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.
