Niagara Falls International to MC Ghee Tyson Airport IAG → TYS

496 nautical miles (571 statute miles) southwest on a straight line, true course 210°, about 220° magnetic at the departure end (variation 10W). At 120 knots that is 3 h 56 min at the quickest height in today's winds (8,500 ft, a 6-knot tailwind), arriving about 1:40 am EDT (05:40 UTC), after sunset at the destination. Right now IAG is VFR, wind from the east (080°) at 8 knots; TYS is marginal VFR, wind from the south-southwest (210°) at 6 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 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 6 forecast points nearest it (BUF, AGC, CMH, CRW, TRI, TYS). 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.
