Bozeman Yellowstone International to Westchester County BZN → HPN

1,642 nautical miles (1,889 statute miles) east on a straight line, true course 086°, about 073° magnetic at the departure end (variation 13E). At 120 knots that is 9 h 07 min at the quickest height in today's winds (39,000 ft, a 60-knot tailwind), arriving about 7:09 am EDT (11:09 UTC). Right now BZN is low IFR, wind calm; HPN is IFR, wind from the northeast (040°) at 7 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: 6 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.

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 eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 14 forecast points nearest it (BIL, MLS, DIK, PIR, ABR, AXN, MSP, LSE, GRB, TVC, CLE, BUF, AVP, JFK). A plus sign is a headwind, a minus sign a tailwind.

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.
