Brownsville/South Padre Island International to Friedman Memorial BRO → SUN
1,340 nautical miles (1,542 statute miles) northwest on a straight line, true course 326°, about 323° magnetic at the departure end (variation 3E). At 120 knots that is 10 h 05 min at the quickest height in today's winds (4,500 ft, a 13-knot tailwind), arriving about 5:18 am MDT (11:18 UTC), after sunset at the destination. Right now BRO is VFR, wind from the east-southeast (110°) at 7 knots; SUN is marginal VFR, wind from the east-southeast (120°) 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: 1 flights in the DOT's last twelve reported months, the route's page.

- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 520 nm of the route.
- AIRMET TANGO 1W: 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 860 to 1190 nm out.
- AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the last 320 nm of the route.
- AIRMET SIERRA 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Over the last 130 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 BRO.

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 13 forecast points nearest it (BRO, CRP, LRD, DRT, INK, ROW, TCC, ABQ, ALS, FMN, GJT, SLC, PIH). 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.
