St. Louis Lambert International to Ted Stevens Anchorage International STL → ANC

2,546 nautical miles (2,929 statute miles) northwest on a straight line, true course 322°, about 323° magnetic at the departure end (variation 1W). At 120 knots that is 20 h 42 min at the quickest height in today's winds (4,500 ft, a 3-knot tailwind), arriving about 1:39 pm AKDT (21:39 UTC). Right now STL is VFR, wind from the southeast (130°) at 7 knots; ANC is marginal VFR, wind from the northwest (320°) 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: 2 flights in the DOT's last twelve reported months, the route's page.

The route the straight line, the warnings crossed, restrictions, pilot reports and the airports along the way · click a mark for its words

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 4C: moderate icing up to 20,000 ft. Over the route from 749 to 819 nm out.
AIRMET TANGO 4W: moderate turbulence above 18,000 ft from 18,000 ft to 36,000 ft. Near the route, 829 nm along 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 STL.

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

BE20 at 14,000 ft, 13 nm southwest, 7:20 pm CDT (00:20 UTC): light turbulence. 439 nm along the route, 13 nm southwest of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 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 10 forecast points nearest it (STL, BRL, DSM, MCW, FSD, ABR, MOT, GGW, GPI, SEA). 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.
