Charlotte/Douglas International to Aspen-Pitkin County/Sardy Field CLT → ASE
1,258 nautical miles (1,447 statute miles) west on a straight line, true course 289°, about 296° magnetic at the departure end (variation 7W). At 120 knots that is 12 h 20 min at the quickest height in today's winds (10,500 ft, a 18-knot headwind), arriving about 12:32 pm MDT (18:32 UTC). Right now CLT is VFR, wind from the west (260°) at 7 knots; ASE is VFR, wind from the west (260°) at 4 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: 69 flights in the DOT's last twelve reported months, the route's page.

- AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 80 to 200 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 609 to 1068 nm out.

- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Near the route, at the destination end.
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 CLT.

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 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 13 forecast points nearest it (GSP, TYS, BNA, CGI, COU, SGF, MKC, SLN, GCK, GLD, PUB, DEN, GJT). 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.
