Cheyenne Rgnl/Jerry Olson Field to Idaho Falls Regional CYS → IDA
352 nautical miles (405 statute miles) northwest on a straight line, true course 296°, about 286° magnetic at the departure end (variation 10E). At 120 knots that is 2 h 42 min at the quickest height in today's winds (8,500 ft, a 10-knot tailwind), arriving about 8:59 pm MDT (02:59 UTC), after sunset at the destination. Right now CYS is VFR, wind from the east-southeast (110°) at 9 knots; IDA is marginal VFR, wind from the north-northwest (340°) at 9 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.

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 3 forecast points nearest it (BFF, LND, 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.
