Dubois Municipal to Mineta San Jose International DUB → SJC
670 nautical miles (771 statute miles) southwest on a straight line, true course 241°, about 231° magnetic at the departure end (variation 10E). At 120 knots that is 5 h 22 min at the quickest height in today's winds (4,500 ft, a 5-knot tailwind), arriving about 9:05 am PDT (16:05 UTC). Right now DUB is VFR, wind from the west-northwest (290°) at 10 knots; SJC is VFR, wind from the south-southeast (160°) at 4 knots. 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.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 6 forecast points nearest it (LND, PIH, BAM, RNO, SAC, SFO). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
