Ellison Onizuka Kona International AT Keahole to Salt Lake City International KOA → SLC
2,575 nautical miles (2,963 statute miles) northeast on a straight line, true course 051°, about 040° magnetic at the departure end (variation 11E). At 120 knots that is 21 h 38 min at the quickest height in today's winds (7,500 ft, a 1-knot headwind), arriving about 5:35 pm MDT (23:35 UTC). Right now KOA is VFR, wind from the west-southwest (250°) at 10 knots; SLC is VFR, wind from the south (180°) at 4 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: 188 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 TANGO 2W: strong surface winds (30 knots or more) (due to sustained surface winds greater than 30 knots). Over the route from 1926 to 1966 nm out.
- AIRMET TANGO 3W: moderate turbulence below 18,000 ft (due to mountain wave) up to 15,000 ft. Near the route, 2186 nm along the route.
- AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the last 319 nm of the route.
- AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Over the last 309 nm of the route.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 250 nm of the route.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 160 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 last 0 nm of the route.
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 KOA.

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 2 forecast points nearest it (KOA, ITO). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
