Dubois Municipal to Raleigh-Durham International DUB → RDU

1,490 nautical miles (1,714 statute miles) east on a straight line, true course 097°, about 087° magnetic at the departure end (variation 10E). At 120 knots that is 9 h 02 min at the quickest height in today's winds (39,000 ft, a 45-knot tailwind), arriving about 7:10 am EDT (11:10 UTC), after sunset at the destination. Right now DUB is IFR, wind from the southeast (130°) at 15 knots, gusting to 25; RDU is VFR, wind from the southwest (230°) at 12 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: 159 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 14 forecast points nearest it (LND, BFF, ONL, OMA, DSM, BRL, SPI, EVV, IND, LOU, CVG, TRI, ROA, RDU). A plus sign is a headwind, a minus sign a tailwind.

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.
