Bozeman Yellowstone International to Long Beach (Daugherty Field) BZN → LGB

787 nautical miles (905 statute miles) southwest on a straight line, true course 207°, about 194° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 06 min at the quickest height in today's winds (4,500 ft, a 9-knot tailwind), arriving about 7:44 am PDT (14:44 UTC). Right now BZN is IFR, wind from the south-southwest (210°) at 6 knots; LGB 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: 16 flights in the DOT's last twelve reported months, the route's page.

The return flight

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 SIERRA 7E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, mist). Over the first 70 nm of the route.
  • AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 548 nm of the route.
  • AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the route from 139 to 398 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 249 to 348 nm out.
  • AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the route from 538 to 777 nm out.

Turbulence AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft, over the route from 538 to 777 nm out. 1 pilot report of turbulence near the line in the last three hours: moderate turbulence, at 35,000 ft, 40 nm northwest, 2:00 am MDT (08:00 UTC). The government's turbulence forecast map ↗

Icing AIRMET in force: moderate icing up to 22,000 ft, over the route from 139 to 398 nm out. No pilot has reported icing near the line in the last three hours. The freezing level is about 8,000 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 BZN.

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

  • UAL1947 at 35,000 ft, 40 nm northwest, 2:00 am MDT (08:00 UTC): moderate turbulence, wind 283° at 44 knots. 577 nm along the route, 40 nm northwest of the line.

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.

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.

Daylight

Sunset at BZN 6:40 pm MDT (00:40 UTC), at LGB 6:20 pm PDT (01:20 UTC) (civil twilight ends 6:45 pm PDT (01:45 UTC)).

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

The wind over the route live wind map, from Windy.com · drag the time bar for the coming hours; the level menu changes the height

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.
