Durango-La Plata County to Patrick Leahy Burlington International DRO → BTV

1,619 nautical miles (1,863 statute miles) northeast on a straight line, true course 063°, about 053° magnetic at the departure end (variation 10E). At 120 knots that is 9 h 28 min at the quickest height in today's winds (39,000 ft, a 51-knot tailwind), arriving about 12:34 pm EDT (16:34 UTC). Right now DRO is VFR, wind calm; BTV is low IFR, wind calm. 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: 1 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.

Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of

AIRMET TANGO 2W: moderate turbulence above 18,000 ft from 35,000 ft to 45,000 ft. Over the first 90 nm of the route.
AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the first 260 nm of the route.
AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 50 to 170 nm out.
AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 38,000 ft. Over the route from 100 to 240 nm out.
AIRMET TANGO 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 260 to 870 nm out.
AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the last 550 nm of the route.
AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 21,000 ft to 33,000 ft. Over the last 110 nm of the route.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 80 nm of the route.
AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the last 70 nm of the route.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from DRO.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 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 16 forecast points nearest it (FMN, ALS, PUB, GLD, GRI, OMA, DSM, DBQ, JOT, MKG, TVC, CLE, BUF, SYR, ALB, BML). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
