Dane County Rgnl/Truax Field to Spokane International MSN → GEG
1,212 nautical miles (1,395 statute miles) northwest on a straight line, true course 293°, about 296° magnetic at the departure end (variation 3W). At 120 knots that is 9 h 42 min at the quickest height in today's winds (4,500 ft, a 5-knot tailwind), arriving about 10:23 am PDT (17:23 UTC). 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 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground), from 1:00 am CDT (06:00 UTC). Over the route from 10 to 159 nm out.
- AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 1:00 am CDT (06:00 UTC). Over the route from 298 to 1133 nm out.
- AIRMET ZULU 2C: moderate icing up to 23,000 ft, from 1:00 am CDT (06:00 UTC). Over the route from 725 to 755 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 1:00 am CDT (06:00 UTC). Over the route from 854 to 1152 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft, from 1:00 am CDT (06:00 UTC). Over the route from 944 to 1133 nm out.
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.

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 11 forecast points nearest it (DBQ, LSE, MSP, AXN, ABR, DIK, MLS, BIL, GTF, GPI, GEG). 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.
