Marquette Sawyer Regional to Falls Intl/Einarson Field SAW → INL
278 nautical miles (320 statute miles) northwest on a straight line, true course 301°, about 305° magnetic at the departure end (variation 4W). At 120 knots that is 2 h 44 min at the quickest height in today's winds (4,500 ft, a 18-knot headwind), arriving about 3:15 pm CDT (20:15 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 SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, mist). Over the first 258 nm of the route.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 24,000 ft to 35,000 ft. Over the whole route.
Turbulence AIRMET in force: moderate turbulence from 24,000 ft to 35,000 ft, over the whole route. No pilot has reported turbulence near the line in the last three hours. 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 13,000 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 SAW.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- P28A at 4,000 ft, 0 nm northwest, 11:39 am EDT (15:39 UTC): overcast from 1,700 ft to 4,000 ft, remarks: during the descent runway 19. At the departure end, 0 nm northwest of the line.

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 3 forecast points nearest it (GRB, DLH, INL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 13th at 12:00 UTC; valid on the 13th at 18:00 UTC for use 14:00 to 21:00 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 1 minutes 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.
