Harrisburg International to James M Cox Dayton International MDT → DAY
343 nautical miles (395 statute miles) west on a straight line, true course 269°, about 280° magnetic at the departure end (variation 11W). At 120 knots that is 2 h 54 min at the quickest height in today's winds (10,500 ft, a 2-knot headwind), arriving about 1:04 am EDT (05:04 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: 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 3 forecast points nearest it (PSB, AGC, CMH). 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 DAY 7:02 pm EDT (23:02 UTC) (civil twilight ends 7:29 pm EDT (23:29 UTC)). At 120 knots the arrival at DAY is before sunrise there (7:43 am EDT (11:43 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.
