Harrisburg International to Watertown International MDT → ART
230 nautical miles (265 statute miles) north on a straight line, true course 008°, about 019° magnetic at the departure end (variation 11W). At 120 knots that is 1 h 13 min at the quickest height in today's winds (34,000 ft, a 69-knot tailwind), arriving about 10:51 pm EDT (02:51 UTC), after sunset at the destination. 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 2 forecast points nearest it (AVP, SYR). 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.

Sunset at MDT 6:32 pm EDT (22:32 UTC), at ART 6:25 pm EDT (22:25 UTC) (civil twilight ends 6:54 pm EDT (22:54 UTC)). At 120 knots the arrival at ART is after sunset there (6:27 pm EDT (22:27 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
