Nantucket Memorial to Burke Lakefront Airport ACK → BKL
523 nautical miles (602 statute miles) west on a straight line, true course 276°, about 290° magnetic at the departure end (variation 14W). At 120 knots that is 4 h 31 min at the quickest height in today's winds (4,500 ft, a 4-knot headwind), arriving about 5:44 am EDT (09:44 UTC), after sunset at the destination. Right now ACK is IFR, wind from the east (080°) at 9 knots, gusting to 18; BKL is marginal VFR, wind from the northwest (320°) at 6 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 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 6 forecast points nearest it (ACK, BDL, JFK, AVP, PSB, CLE). 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.
