Daniel K Inouye International to City Of Colorado Springs Municipal HNL → COS

2,913 nautical miles (3,352 statute miles) northeast on a straight line, true course 056°, about 045° magnetic at the departure end (variation 11E). At 120 knots that is 23 h 30 min at the quickest height in today's winds (24,000 ft, a 4-knot tailwind), arriving about 1:23 am MDT (07:23 UTC), after sunset at the destination. Right now HNL is VFR, wind from the north-northeast (020°) at 4 knots; COS is VFR, wind from the east-southeast (110°) at 5 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: 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 SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the route from 2374 to 2873 nm out.
AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the route from 2474 to 2823 nm out.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft (due to mountain wave) from 34,000 ft to 45,000 ft. Over the last 389 nm of the route.
AIRMET TANGO 2W: moderate turbulence below 18,000 ft (due to mountain wave) up to 22,000 ft. Over the last 389 nm of the route.
AIRMET TANGO 3W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 2534 to 2613 nm out.
AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 2833 to 2863 nm out.

Turbulence AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft, over the route from 2204 to 2374 nm out; AIRMET in force: moderate turbulence from 14,000 ft to 18,000 ft, over the route from 2224 to 2294 nm out. AIRMET in force: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground), over the route from 2534 to 2613 nm out. 3 pilot reports of turbulence near the line in the last three hours: moderate turbulence, at 20,000 ft, 36 nm north, 9:15 pm HST (07:15 UTC); light to moderate turbulence, at 10,000 ft, 36 nm north, 8:37 pm HST (06:37 UTC). The government's turbulence forecast map ↗

Icing AIRMET in force: moderate icing up to 22,000 ft, over the route from 2474 to 2823 nm out. 1 pilot report of icing near the line in the last three hours: light to moderate rime icing from 10,000 ft to 20,000 ft, 36 nm north, 8:37 pm HST (06:37 UTC). The freezing level is about 15,500 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 HNL.

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 UTC · at 120 knots true airspeed

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 3 forecast points nearest it (HNL, OGG, ITO). 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.
