Portland International to General Edward Lawrence Logan International PDX → BOS

2,199 nautical miles (2,530 statute miles) east on a straight line, true course 076°, about 060° magnetic at the departure end (variation 16E). At 120 knots that is 12 h 30 min at the quickest height in today's winds (39,000 ft, a 56-knot tailwind), arriving about 1:31 am EDT (05:31 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: 1,323 flights in the DOT's last twelve reported months, the route's page.

Icing No icing warning in force along the route. 1 pilot report of icing near the line in the last three hours: light icing from 12,000 ft to 14,000 ft, 39 nm south, 7:28 am PDT (14:28 UTC). The freezing level is about 12,000 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 PDX.

Winds aloft along the route, and the time en route the forecast for use 14:00–21:00 UTC · at 120 knots true airspeed

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 19 forecast points nearest it (PDX, YKM, LWS, GPI, GTF, BIL, GGW, MLS, DIK, MOT, GFK, AXN, DLH, GRB, TVC, BUF, SYR, ALB, BOS). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 12:00 UTC; valid on the 13th at 18:00 UTC for use 14:00 to 21:00 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 1 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 PDX 6:26 pm PDT (01:26 UTC), at BOS 6:05 pm EDT (22:05 UTC) (civil twilight ends 6:33 pm EDT (22:33 UTC)). At 120 knots the arrival at BOS is before sunrise there (6:55 am EDT (10:55 UTC)).

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