Santa Barbara Municipal to Great Falls International SBA → GTF
872 nautical miles (1,003 statute miles) northeast on a straight line, true course 023°, about 009° magnetic at the departure end (variation 14E). At 120 knots that is 7 h 20 min at the quickest height in today's winds (39,000 ft, a 1-knot headwind), arriving about 10:42 am MDT (16:42 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: moderate turbulence below 18,000 ft (due to mountain wave) up to 10,000 ft. Over the route from 10 to 129 nm out.
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the last 743 nm of the route.
- AIRMET TANGO 1W: moderate turbulence below 18,000 ft from 14,000 ft to 18,000 ft. Over the route from 139 to 297 nm out.
- AIRMET ZULU 1C: moderate icing from 7,000 ft to 16,000 ft. Over the route from 188 to 297 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 307 to 773 nm out.
- AIRMET SIERRA 11E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 367 to 515 nm out.
- AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the route from 376 to 594 nm out.
Turbulence AIRMET in force: moderate turbulence (due to mountain wave) up to 10,000 ft, over the route from 10 to 129 nm out; AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft, over the last 743 nm of the route. No pilot has reported turbulence near the line in the last three hours. The government's turbulence forecast map ↗
Icing AIRMET in force: moderate icing from 7,000 ft to 16,000 ft, over the route from 188 to 297 nm out; AIRMET in force: moderate icing up to 22,000 ft, over the route from 376 to 594 nm out. No pilot has reported icing near the line in the last three hours. The freezing level is about 7,000 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 SBA.

Based on data from the 13th at 06:00 UTC; valid on the 13th 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.

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.
