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 11 h 32 min at the quickest height in today's winds (4,500 ft, a 12-knot headwind), arriving about 9:34 am MDT (15:34 UTC). Right now BNA is VFR, wind from the south (170°) at 6 knots; BZN is marginal VFR, wind from the south-southeast (150°) at 3 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: 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.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET ZULU 1C: moderate icing up to 22,000 ft. Over the route from 956 to 1076 nm out.
- AIRMET SIERRA 1E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist). Over the last 189 nm of the route.
- AIRMET SIERRA 9E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist). Near the route, 1165 nm along the route.
Turbulence No turbulence warning in force along the route. 2 pilot reports of turbulence near the line in the last three hours: light turbulence above 21,000 ft, 6 nm southwest, 9:02 pm CDT (02:02 UTC); light turbulence above 21,000 ft, 14 nm north, 8:52 pm CDT (01:52 UTC). The government's turbulence forecast map ↗
Icing AIRMET in force: moderate icing up to 22,000 ft, over the route from 956 to 1076 nm out. 1 pilot report of icing near the line in the last three hours: light rime icing, at 21,000 ft, 6 nm southwest, 9:02 pm CDT (02:02 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 BNA.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first

Winds aloft along the route, and the time en route the forecast for use 02:00–09:00 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 (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 13th at 00:00 UTC; valid on the 13th 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.

From the FAA's notice service (NOTAMs), the site's copy refreshed every few minutes; last checked 2 minutes ago. The FAA has so far issued eFlight its test feed, which misses some notices (checked against the FAA's own search on 12 October: about a third missing at Santa Barbara and Burbank, none at Atlanta or Las Vegas); the request for the full feed is with the FAA. Times are local to the field. This is for planning; the legal briefing comes from Flight Service or the FAA's own tools.

Sunset at BNA 6:13 pm CDT (23:13 UTC), at BZN 6:42 pm MDT (00:42 UTC) (civil twilight ends 7:12 pm MDT (01:12 UTC)).
Each restriction opens the FAA's own page with the exact area, heights and times.
The wind over the route live wind map, from Windy.com · drag the time bar for the coming hours; the level menu changes the height
Colours show wind speed, the moving lines its direction, at the surface unless you pick a height. Map and forecast by Windy.com; a second opinion beside the government's winds-aloft table above.

Sources: the Aviation Weather Center's data service (SIGMETs, AIRMETs, graphical AIRMETs, pilot reports, winds and temperatures aloft, observations and terminal forecasts), the National Weather Service radar, the Weather Prediction Center's charts, the FAA's temporary flight restriction list and shapes, and the FAA's airport file for the positions, elevations and magnetic variation. Fetched when the page is viewed and kept a few minutes. Each leg is the straight line between its two airports; airways, terrain and airspace are not considered.
