Morristown Municipal to Blue Grass Airport MMU → LEX
501 nautical miles (576 statute miles) west on a straight line, true course 254°, about 267° magnetic at the departure end (variation 13W). At 120 knots that is 4 h 17 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 8:00 am EDT (12:00 UTC). 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 8 forecast points nearest it (JFK, AVP, PSB, AGC, EKN, CRW, CVG, LOU). 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.
