Denver International to Boise Air Trml/Gowen Field DEN → BOI

563 nautical miles (648 statute miles) northwest on a straight line, true course 297°, about 289° magnetic at the departure end (variation 8E). At 120 knots that is 4 h 30 min at the quickest height in today's winds (18,000 ft, a 5-knot tailwind), arriving about 11:12 am MDT (17:12 UTC). Right now DEN is IFR, wind from the northeast (050°) at 8 knots; BOI is VFR, wind from the west (280°) at 10 knots. 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: 6,118 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 9E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the first 20 nm of the route.
AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft. Near the route, at the departure end.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 138 nm of the route.
AIRMET SIERRA 2E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the route from 30 to 128 nm out.
AIRMET ZULU 1C: moderate icing up to 21,000 ft. Over the route from 30 to 494 nm out.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 24,000 ft to 36,000 ft. Over the route from 39 to 188 nm out.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the last 355 nm of the route.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 227 to 503 nm out.

Turbulence AIRMET in force: moderate turbulence (due to mountain wave) up to 22,000 ft, near the route, at the departure end; AIRMET in force: moderate turbulence from 24,000 ft to 36,000 ft, over the route from 39 to 188 nm out. 4 pilot reports of turbulence near the line in the last three hours: moderate turbulence from 13,000 ft to 18,000 ft, 33 nm southeast, 6:20 am MDT (12:20 UTC); light chop turbulence, at 10,000 ft, 11 nm southeast, 6:14 am MDT (12:14 UTC). The government's turbulence forecast map ↗

Icing AIRMET in force: moderate icing up to 21,000 ft, over the route from 30 to 494 nm out. A pilot reported no icing, at 7,000 ft, 1 nm east, 6:05 am MDT (12:05 UTC). The freezing level is about 10,000 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 DEN.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 UTC · at 120 knots true airspeed

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 4 forecast points nearest it (DEN, RKS, PIH, BOI). A plus sign is a headwind, a minus sign a tailwind.

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.

Sunset at DEN 6:21 pm MDT (00:21 UTC), at BOI 7:03 pm MDT (01:03 UTC) (civil twilight ends 7:32 pm MDT (01:32 UTC)).
