Cincinnati/Northern Kentucky International to Billings Logan International CVG → BIL

1,128 nautical miles (1,298 statute miles) northwest on a straight line, true course 299°, about 305° magnetic at the departure end (variation 6W). At 120 knots that is 10 h 21 min at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 11:54 pm MDT (05:54 UTC), after sunset at the destination. Right now CVG is VFR, wind from the south (190°) at 7 knots; BIL is marginal VFR, wind calm. 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.

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 4E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist), from 2:00 pm EDT (18:00 UTC). Over the last 519 nm of the route.
AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist), from 2:00 pm EDT (18:00 UTC). Over the last 30 nm of the route.

Turbulence No turbulence warning in force along the route. 4 pilot reports of turbulence near the line in the last three hours: light turbulence, at 18,000 ft, 45 nm northeast, 1:42 pm EDT (17:42 UTC); light chop turbulence from 18,000 ft to 24,000 ft, 15 nm southwest, 12:48 pm EDT (16:48 UTC). The government's turbulence forecast map ↗

Icing No icing warning in force along the route. A pilot reported no icing, at 24,000 ft, 40 nm southwest, 2:41 pm EDT (18:41 UTC). The freezing level is about 13,500 ft (from the winds-aloft temperatures), so icing is possible in cloud above that. The government's icing forecast map ↗

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 CVG.

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

PC12 at 24,000 ft, 40 nm southwest, 2:41 pm EDT (18:41 UTC): no turbulence, no icing, vmc. At the departure end, 40 nm southwest of the line.

Winds aloft along the route, and the time en route the forecast for use 14:00–21:00 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 12 forecast points nearest it (CVG, IND, JOT, BRL, DBQ, DSM, MCW, FSD, PIR, RAP, MLS, BIL). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 12:00 UTC; valid on the 12th at 18:00 UTC for use 14:00 to 21:00 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.
