Morristown Municipal to MC Ghee Tyson Airport MMU → TYS
541 nautical miles (623 statute miles) southwest on a straight line, true course 239°, about 252° magnetic at the departure end (variation 13W). At 120 knots that is 4 h 28 min at the quickest height in today's winds (6,500 ft, a 1-knot tailwind), arriving about 7:08 am EDT (11:08 UTC), after sunset at the destination. Right now MMU is marginal VFR, wind from the north-northeast (030°) at 5 knots; TYS is marginal VFR, wind from the south-southwest (210°) at 5 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: 1 flights in the DOT's last twelve reported months, the route's page.

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 7 forecast points nearest it (JFK, AVP, PSB, EKN, ROA, TRI, TYS). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th 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.
