Dubois Municipal to Nashville International DUB → BNA

1,146 nautical miles (1,319 statute miles) east on a straight line, true course 105°, about 095° magnetic at the departure end (variation 10E). At 120 knots that is 6 h 44 min at the quickest height in today's winds (39,000 ft, a 50-knot tailwind), arriving about 2:19 am CDT (07:19 UTC), after sunset at the destination. Right now DUB is marginal VFR, wind from the east (100°) at 12 knots; BNA is VFR, wind variable at 3 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: 401 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 9 forecast points nearest it (LND, BFF, GRI, OMA, MKC, COU, STL, CGI, BNA). 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.
