Willow Run Airport to Savannah/Hilton Head International YIP → SAV
617 nautical miles (710 statute miles) south on a straight line, true course 169°, about 175° magnetic at the departure end (variation 6W). At 120 knots that is 4 h 36 min at the quickest height in today's winds (5,500 ft, a 14-knot tailwind), arriving about 2:14 am EDT (06:14 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: 6 flights in the DOT's last twelve reported months, the route's page.

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.

Daylight
Sunset at YIP 6:57 pm EDT (22:57 UTC), at SAV 6:56 pm EDT (22:56 UTC) (civil twilight ends 7:20 pm EDT (23:20 UTC)). At 120 knots the arrival at SAV is before sunrise there (7:26 am EDT (11:26 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.
