Louisville Muhammad Ali International to Dubois Municipal SDF → DUB

1,130 nautical miles (1,300 statute miles) northwest on a straight line, true course 294°, about 299° magnetic at the departure end (variation 5W). At 120 knots that is 9 h 30 min at the quickest height in today's winds (4,500 ft, a 1-knot headwind), arriving about 5:09 am MDT (11:09 UTC), after sunset at the destination. Right now SDF is VFR, wind from the southwest (220°) at 4 knots; DUB is IFR, wind from the east-southeast (110°) at 10 knots, gusting to 14. 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: 195 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 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 10 forecast points nearest it (LOU, EVV, SPI, BRL, DSM, OMA, GRI, ONL, BFF, LND). 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.
