Waco Regional to Rapid City Regional ACT → RAP
795 nautical miles (915 statute miles) north on a straight line, true course 341°, about 334° magnetic at the departure end (variation 7E). At 120 knots that is 5 h 38 min at the quickest height in today's winds (4,500 ft, a 21-knot tailwind), arriving about 6:20 am MDT (12:20 UTC), after sunset at the destination. Right now ACT is VFR, wind from the south (170°) at 15 knots; RAP is low IFR, 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: 1 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 C11C: thunderstorms (a convective SIGMET) up to 31,000 ft, moving from the southwest at 40 knots, until 2:55 am CDT (07:55 UTC). Over the last 20 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 ACT.

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.
