Cleveland-Hopkins International to Nantucket Memorial CLE → ACK

531 nautical miles (612 statute miles) east on a straight line, true course 087°, about 095° magnetic at the departure end (variation 8W). At 120 knots that is 3 h 07 min at the quickest height in today's winds (39,000 ft, a 50-knot tailwind), arriving about 4:18 am EDT (08:18 UTC), after sunset at the destination. Right now CLE is low IFR, wind from the west-northwest (300°) at 6 knots; ACK is IFR, wind from the east (080°) at 9 knots, gusting to 18. 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.

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 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 7 forecast points nearest it (CLE, AGC, PSB, AVP, JFK, BDL, ACK). 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.
