Plan a flight · Tue 3:53 am EDT (07:53 UTC)

Laurence G Hanscom Field to Baltimore/Washington International Thurgood Marshall BED → BWI

314 nautical miles (362 statute miles) southwest on a straight line, true course 233°, about 249° magnetic at the departure end (variation 16W). At 120 knots that is 2 h 30 min at the quickest height in today's winds (4,500 ft, a 6-knot tailwind), arriving about 6:23 am EDT (10:23 UTC), after sunset at the destination. 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 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 1E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist, fog). Over the first 79 nm of the route.
AIRMET SIERRA 6E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, mist, fog). Over the last 167 nm of the route.

Turbulence No turbulence warning in force along the route. No pilot has reported turbulence near the line in the last three hours. The government's turbulence forecast map ↗

Icing No icing warning in force along the route. No pilot has reported icing near the line in the last three hours. The freezing level is about 13,000 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗

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 BED.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 4 forecast points nearest it (BOS, BDL, JFK, ACY). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 00:00 UTC; valid on the 13th 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.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked 2 minutes ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.

Daylight

Sunset at BED 6:06 pm EDT (22:06 UTC), at BWI 6:31 pm EDT (22:31 UTC) (civil twilight ends 6:58 pm EDT (22:58 UTC)). At 120 knots the arrival at BWI is before sunrise there (7:14 am EDT (11:14 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times.
