Dubois Municipal to Denver International DUB → DEN

315 nautical miles (363 statute miles) southeast on a straight line, true course 133°, about 123° magnetic at the departure end (variation 10E). At 120 knots that is 2 h 14 min at the quickest height in today's winds (39,000 ft, a 21-knot tailwind), arriving about 10:00 pm MDT (04:00 UTC), after sunset at the destination. Right now DUB is IFR, wind from the southeast (130°) at 14 knots, gusting to 18; DEN is VFR, wind from the south (170°) at 13 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: 274 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.

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.
