Nashville International to Bozeman Yellowstone International BNA → BZN

1,245 nautical miles (1,433 statute miles) northwest on a straight line, true course 305°, about 308° magnetic at the departure end (variation 3W). At 120 knots that is 10 h 07 min at the quickest height in today's winds (4,500 ft, a 3-knot tailwind), arriving about 6:16 am MDT (12:16 UTC), after sunset at the destination. 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: 266 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.

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 BNA.

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 (BNA, CGI, STL, COU, MKC, OMA, GRI, ONL, RAP, MLS, BIL, DLN). 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.

Daylight

Sunset at BNA 6:15 pm CDT (23:15 UTC), at BZN 6:44 pm MDT (00:44 UTC) (civil twilight ends 7:14 pm MDT (01:14 UTC)). At 120 knots the arrival at BZN is before sunrise there (7:36 am MDT (13:36 UTC)).

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (closed runways, lights out) are not shown: the FAA's notice search is not open to sites like this one at this time.
