Auburn/Lewiston Municipal to Lancaster Airport LEW → LNS

357 nautical miles (410 statute miles) southwest on a straight line, true course 231°, about 248° magnetic at the departure end (variation 17W). At 120 knots that is 3 h 06 min at the quickest height in today's winds (4,500 ft, a 5-knot headwind), arriving about 4:50 am EDT (08:50 UTC), after sunset at the destination. Right now LEW is VFR, wind calm; LNS is IFR, wind from the northeast (050°) at 10 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.

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 5 forecast points nearest it (PWM, BOS, BDL, JFK, AVP). 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.
