Portland International Jetport to Charleston Afb/Intl Airport PWM → CHS
790 nautical miles (910 statute miles) southwest on a straight line, true course 219°, about 234° magnetic at the departure end (variation 15W). At 120 knots that is 7 h 23 min at the quickest height in today's winds (4,500 ft, a 13-knot headwind), arriving about 9:04 am EDT (13:04 UTC). Right now PWM is marginal VFR, wind from the north-northeast (020°) at 3 knots; CHS is VFR, wind from the west-southwest (250°) at 4 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: 263 flights in the DOT's last twelve reported months, the route's page.

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 10 forecast points nearest it (PWM, BOS, BDL, JFK, ACY, ORF, RDU, ILM, FLO, CHS). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th 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.
