Long Island Mac Arthur Airport to Hancock County/Bar Harbor ISP → BHB
303 nautical miles (349 statute miles) northeast on a straight line, true course 042°, about 056° magnetic at the departure end (variation 14W). At 120 knots that is 1 h 41 min at the quickest height in today's winds (39,000 ft, a 60-knot tailwind), arriving about 7:26 am EDT (11:26 UTC). Right now ISP is IFR, wind from the northeast (040°) at 11 knots; BHB is VFR, wind calm. 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.

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 4 forecast points nearest it (BDL, BOS, PWM, BGR). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
