Salt Lake City International to Buffalo Niagara International SLC → BUF

1,483 nautical miles (1,706 statute miles) east on a straight line, true course 074°, about 063° magnetic at the departure end (variation 11E). At 120 knots that is 8 h 17 min at the quickest height in today's winds (39,000 ft, a 59-knot tailwind), arriving about 6:10 am EDT (10:10 UTC), after sunset at the destination. Right now SLC is VFR, wind from the east-northeast (070°) at 3 knots; BUF is VFR, wind from the east (090°) 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: 2 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 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 12 forecast points nearest it (SLC, RKS, BFF, ONL, FSD, MCW, LSE, DBQ, GRB, MKG, CLE, BUF). 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.
