St. Louis Lambert International to Phoenix Sky Harbor International STL → PHX

1,094 nautical miles (1,259 statute miles) west on a straight line, true course 260°, about 261° magnetic at the departure end (variation 1W). At 120 knots that is 11 h 17 min at the quickest height in today's winds (10,500 ft, a 23-knot headwind), arriving about 10:00 am MST (17:00 UTC). 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: 4,624 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

  • SIGMET 7C: thunderstorms (a convective SIGMET) up to 34,000 ft, moving from the southwest at 40 knots, until 1:55 am CDT (06:55 UTC). Over the route from 597 to 766 nm out.

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.

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, COU, SGF, MKC, ICT, GAG, AMA, TCC, ABQ, PHX). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th 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.

Sunset at STL 6:27 pm CDT (23:27 UTC), at PHX 5:58 pm MST (00:58 UTC) (civil twilight ends 6:23 pm MST (01:23 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
