Portland International Jetport to Knox County Regional PWM → RKD
58 nautical miles (67 statute miles) northeast on a straight line, true course 064°, about 079° magnetic at the departure end (variation 15W). At 120 knots that is 15 min at the quickest height in today's winds (39,000 ft, a 107-knot tailwind), arriving about 10:18 pm EDT (02:18 UTC), after sunset at the destination. Right now PWM is marginal VFR, wind calm; RKD is VFR, wind from the southwest (230°) at 7 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.

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 22,000 ft. 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 TANGO 2W: moderate turbulence below 18,000 ft up to 13,000 ft. Over the whole route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Near the route, at the departure 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 PWM.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- A333 at 15,000 ft, 41 nm southwest, 9:37 pm EDT (01:37 UTC): moderate chop turbulence up to 15,000 ft, remarks: during the climb. At the departure end, 41 nm southwest of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 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 2 forecast points nearest it (PWM, BGR). 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.

Daylight
Sunset at PWM 6:03 pm EDT (22:03 UTC), at RKD 5:58 pm EDT (21:58 UTC) (civil twilight ends 6:27 pm EDT (22:27 UTC)). At 120 knots the arrival at RKD is after sunset there (5:59 pm EDT (21:59 UTC)).
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.
