Baltimore/Washington International Thurgood Marshall to Willow Run Airport BWI → YIP
362 nautical miles (417 statute miles) northwest on a straight line, true course 303°, about 314° magnetic at the departure end (variation 11W). At 120 knots that is 3 h 14 min at the quickest height in today's winds (4,500 ft, a 8-knot headwind), arriving about 4:26 am EDT (08:26 UTC), after sunset at the destination. Right now BWI is marginal VFR, wind from the north-northeast (020°) at 9 knots, gusting to 16; YIP is marginal 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: 4 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed
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, 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.
