Yellowstone Regional to Denver International COD → DEN

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 136 nm of the route.
• AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the first 272 nm of the route.
• AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 321 nm of the route.
• AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 24,000 ft to 36,000 ft. Over the route from 87 to 291 nm out.
• AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft. Near the route, 301 nm along the route.
• AIRMET TANGO 1W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Near the route, at the destination end.

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 COD.

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.

Daylight

Sunset at COD 6:33 pm MDT (00:33 UTC), at DEN 6:21 pm MDT (00:21 UTC) (civil twilight ends 6:48 pm MDT (00:48 UTC)). At 120 knots the arrival at DEN is before sunrise there (7:06 am MDT (13:06 UTC)).
