Washington Dulles International to Greater Binghamton/Edwin A Link Field IAD → BGM
207 nautical miles (238 statute miles) north on a straight line, true course 019°, about 029° magnetic at the departure end (variation 10W). At 120 knots that is 1 h 19 min at the quickest height in today's winds (34,000 ft, a 38-knot tailwind), arriving about 12:22 am EDT (04:22 UTC), after sunset at the destination. Right now IAD is IFR, wind from the north-northwest (340°) at 10 knots; BGM is low IFR, wind from the northeast (050°) 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: 2 flights in the DOT's last twelve reported months, the route's page.
The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words
Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the whole route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the whole route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 118 nm of the route.
- AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 13,000 ft. Near the route, 197 nm along the route.
- AIRMET ZULU 1C: moderate icing up to 25,000 ft. Near the route, at the destination end.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from IAD.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B752 at 30,000 ft, 46 nm west, 10:26 pm EDT (02:26 UTC): moderate chop turbulence, remarks: zob. 69 nm along the route, 46 nm west of the line.

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 (PSB, AVP). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
