Oakland County International to Laredo International PTK → LRD

1,198 nautical miles (1,378 statute miles) southwest on a straight line, true course 226°, about 233° magnetic at the departure end (variation 7W). At 120 knots that is 9 h 44 min at the quickest height in today's winds (30,000 ft, a 3-knot tailwind), arriving about 4:42 am CDT (09:42 UTC), after sunset at the destination. Right now PTK is IFR, wind calm; LRD is VFR, wind from the south-southeast (150°) at 15 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: 55 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 SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the first 40 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 PTK.

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

B737 at 33,000 ft, 37 nm southeast, 5:10 pm EDT (21:10 UTC): moderate chop turbulence, remarks: zme. 469 nm along the route, 37 nm southeast 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 9 forecast points nearest it (FWA, IND, EVV, CGI, LIT, SHV, CLL, SAT, LRD). 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.
