Boise Air Trml/Gowen Field to Roberts Fld/Redmond Municipal BOI → RDM
217 nautical miles (250 statute miles) west on a straight line, true course 283°, about 270° magnetic at the departure end (variation 13E). At 120 knots that is 1 h 38 min at the quickest height in today's winds (12,500 ft, a 13-knot tailwind), arriving about 11:49 pm PDT (06:49 UTC), after sunset at the destination. Right now BOI is VFR, wind from the west (280°) at 6 knots; RDM 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: 12 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: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the first 197 nm of the route.
- AIRMET TANGO 5W: moderate turbulence below 18,000 ft from 14,000 ft to 18,000 ft. Over the route from 59 to 187 nm out.
Turbulence AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft, over the first 197 nm of the route; AIRMET in force: moderate turbulence from 14,000 ft to 18,000 ft, over the route from 59 to 187 nm out. 1 pilot report of turbulence near the line in the last three hours: moderate chop turbulence, at 36,000 ft, 23 nm south, 10:43 pm MDT (04:43 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 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 BOI.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B38M at 36,000 ft, 23 nm south, 10:43 pm MDT (04:43 UTC): moderate chop turbulence, remarks: zse. 118 nm along the route, 23 nm south 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 2 forecast points nearest it (BOI, RDM). 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 2 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.
