Waterloo Regional to Patrick Leahy Burlington International ALO → BTV
844 nautical miles (971 statute miles) east on a straight line, true course 076°, about 076° magnetic at the departure end (variation 0E). At 120 knots that is 5 h 18 min at the quickest height in today's winds (39,000 ft, a 39-knot tailwind), arriving about 1:35 pm EDT (17:35 UTC). Right now ALO is VFR, wind from the south (170°) at 5 knots; BTV is marginal VFR, 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: 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 first 50 nm of the route.
- 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 477 nm of the route.
- AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Near the route, 457 nm along the route.
- AIRMET TANGO 3W: moderate turbulence above 18,000 ft from 24,000 ft to 33,000 ft. Over the last 109 nm of the route.
- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, mist). Over the last 79 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 ALO.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B38M at 32,000 ft, 50 nm west, 6:35 am CDT (11:35 UTC): light chop turbulence above 32,000 ft. At the departure end, 50 nm west of the line.

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 7 forecast points nearest it (DBQ, GRB, MKG, TVC, BUF, SYR, ALB). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
