General Edward Lawrence Logan International to Presque Isle International BOS → PQI
289 nautical miles (333 statute miles) northeast on a straight line, true course 025°, about 040° magnetic at the departure end (variation 15W). At 120 knots that is 1 h 31 min at the quickest height in today's winds (39,000 ft, a 70-knot tailwind), arriving about 9:19 pm EDT (01:19 UTC), after sunset at the destination. Right now BOS is marginal VFR, wind from the southeast (130°) at 4 knots; PQI is VFR, wind from the south-southwest (200°) 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: 711 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 ZULU 1C: moderate icing up to 24,000 ft. Over the first 120 nm of the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the whole route.
- AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the first 149 nm of the route.
- AIRMET TANGO 6W: moderate turbulence below 18,000 ft up to 7,000 ft. Over the last 130 nm of the route.
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 BOS.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

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 4 forecast points nearest it (BOS, PWM, BGR, CAR). 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.

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
