Mineta San Jose International to Willow Run Airport SJC → YIP

1,780 nautical miles (2,048 statute miles) east on a straight line, true course 068°, about 055° magnetic at the departure end (variation 13E). At 120 knots that is 10 h 25 min at the quickest height in today's winds (39,000 ft, a 51-knot tailwind), arriving about 12:01 pm EDT (16:01 UTC). Right now SJC is VFR, wind from the southeast (140°) at 4 knots; 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: 1 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 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 16 forecast points nearest it (SFO, SAC, BIH, ELY, SLC, RKS, DEN, BFF, ONL, OMA, DSM, MCW, DBQ, JOT, MKG, FWA). 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.
