Dubois Municipal to Dallas-Fort Worth International DUB → DFW

873 nautical miles (1,004 statute miles) southeast on a straight line, true course 133°, about 123° magnetic at the departure end (variation 10E). At 120 knots that is 6 h 04 min at the quickest height in today's winds (39,000 ft, a 24-knot tailwind), arriving about 2:43 am CDT (07:43 UTC), after sunset at the destination. Right now DUB is IFR, wind from the east-southeast (110°) at 10 knots, gusting to 14; DFW is VFR, wind from the south (170°) at 7 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: 515 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 20:00–03:00 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 8 forecast points nearest it (LND, RKS, DEN, PUB, GCK, GAG, SPS, DAL). 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.
