Dane County Rgnl/Truax Field to Greenville Spartanburg International MSN → GSP

596 nautical miles (685 statute miles) southeast on a straight line, true course 144°, about 147° magnetic at the departure end (variation 3W). At 120 knots that is 3 h 11 min at the quickest height in today's winds (34,000 ft, a 67-knot tailwind), arriving about 5:18 am EDT (09:18 UTC), after sunset at the destination. Right now MSN is VFR, wind variable at 3 knots; GSP is 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: 3 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 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 first 129 nm of the route.
AIRMET SIERRA 6E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, mist, fog). Over the route from 437 to 486 nm out.
AIRMET SIERRA 4E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist, fog). Over the route from 447 to 476 nm out.

Turbulence No turbulence warning in force along the route. AIRMET in force: 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 129 nm of the route. 1 pilot report of turbulence near the line in the last three hours: light chop turbulence from 24,000 ft to 28,000 ft, 31 nm northeast, 11:50 pm CDT (04:50 UTC). The government's turbulence forecast map ↗

Icing No icing warning in force along the route. No pilot has reported icing near the line in the last three hours. The freezing level is about 14,500 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗

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 MSN.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

E170 at 24,000 ft, 31 nm northeast, 11:50 pm CDT (04:50 UTC): light chop turbulence from 24,000 ft to 28,000 ft. 208 nm along the route, 31 nm northeast 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 8 forecast points nearest it (DBQ, JOT, IND, CVG, LOU, TYS, TRI, GSP). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 00:00 UTC; valid on the 13th 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.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked a minute ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.

Daylight

Sunset at MSN 6:18 pm CDT (23:18 UTC), at GSP 6:56 pm EDT (22:56 UTC) (civil twilight ends 7:22 pm EDT (23:22 UTC)). At 120 knots the arrival at GSP is before sunrise there (7:32 am EDT (11:32 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times.

Colours show wind speed, the moving lines its direction, at the surface unless you pick a height. Map and forecast by Windy.com; a second opinion beside the government's winds-aloft table above.
