Oakland County International to Del Rio International PTK → DRT
1,162 nautical miles (1,337 statute miles) southwest on a straight line, true course 232°, about 239° magnetic at the departure end (variation 7W). At 120 knots that is 10 h 58 min at the quickest height in today's winds (39,000 ft, a 14-knot headwind), arriving about 4:43 pm CDT (21:43 UTC). Right now PTK is IFR, wind from the southwest (220°) at 5 knots; DRT is marginal VFR, wind from the east-southeast (110°) at 8 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: 3 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 129 nm of the route.
- AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground). Over the route from 576 to 606 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 PTK.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- B739 at 9,000 ft, 15 nm east, 6:33 am EDT (10:33 UTC): no turbulence, no icing, clear from 9,000 ft to 60,000 ft, wind 295° at 13 knots, remarks: during the descent. At the departure end, 15 nm east of the line.

Winds aloft along the route, and the time en route the forecast for use 08:00–15:00 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 (FWA, IND, SPI, STL, SGF, FSM, DAL, ABI, SAT, DRT). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
