Heber Valley Airport to Akiachak Seaplane Base HCR → KKI

2,185 nautical miles (2,514 statute miles) northwest on a straight line, true course 321°, about 310° magnetic at the departure end (variation 11E). At 120 knots that is 18 h 50 min at the quickest height in today's winds (4,500 ft, a 4-knot headwind), arriving about 6:44 pm AKDT (02:44 UTC). Right now HCR 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: 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 ZULU 1C: moderate icing up to 22,000 ft. Over the first 190 nm of the route.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the first 219 nm of the route.
AIRMET SIERRA 11E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Near the route, 130 nm along the route.
AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Over the route from 319 to 409 nm out.

Turbulence AIRMET in force: moderate turbulence from 18,000 ft to 39,000 ft, over the route from 319 to 409 nm out. 1 pilot report of turbulence near the line in the last three hours: moderate turbulence from 23,000 ft to 26,000 ft, 37 nm southwest, 12:48 am MDT (06:48 UTC). The government's turbulence forecast map ↗

Icing AIRMET in force: moderate icing up to 22,000 ft, over the first 190 nm of the route. A pilot reported no icing, at 2,000 ft, 14 nm southwest, 12:44 am MDT (06:44 UTC). The freezing level is about 10,500 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 HCR.

Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

B39M at 26,000 ft, 37 nm southwest, 12:48 am MDT (06:48 UTC): moderate turbulence from 23,000 ft to 26,000 ft. 200 nm along the route, 37 nm southwest of the line.

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 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 6 forecast points nearest it (SLC, PIH, BOI, LWS, YKM, SEA). 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.
