John Glenn Columbus International to Portland International Jetport CMH → PWM

603 nautical miles (694 statute miles) northeast on a straight line, true course 065°, about 072° magnetic at the departure end (variation 7W). At 120 knots that is 3 h 11 min at the quickest height in today's winds (39,000 ft, a 69-knot tailwind), arriving about 11:43 pm EDT (03:43 UTC), after sunset at the destination. Right now CMH is marginal VFR, wind from the north-northwest (340°) at 9 knots; PWM is VFR, wind from the south-southwest (200°) at 5 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: 140 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 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 9 forecast points nearest it (CMH, CLE, AGC, PSB, AVP, SYR, ALB, BOS, PWM). 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.
