Portland International Jetport to Wilmington International PWM → ILM
665 nautical miles (765 statute miles) southwest on a straight line, true course 215°, about 230° magnetic at the departure end (variation 15W). At 120 knots that is 5 h 12 min at the quickest height in today's winds (4,500 ft, a 8-knot tailwind), arriving about 11:13 am EDT (15:13 UTC). Right now PWM is VFR, wind calm; ILM is IFR, wind from the west (260°) at 8 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: 1 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, fog). Over the first 466 nm of the route.
- AIRMET ZULU 1C: moderate icing from 12,000 ft to 24,000 ft. Over the first 20 nm of the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 33,000 ft. Over the first 407 nm of the route.
- AIRMET TANGO 2W: moderate turbulence above 18,000 ft from 28,000 ft to 41,000 ft. Over the last 248 nm of the route.
- AIRMET SIERRA 5E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft). Over the route from 615 to 645 nm out.
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.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 7 forecast points nearest it (PWM, BOS, BDL, JFK, ACY, ORF, ILM). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
