John Glenn Columbus International to Smyrna Airport CMH → MQY
295 nautical miles (339 statute miles) southwest on a straight line, true course 217°, about 224° magnetic at the departure end (variation 7W). At 120 knots that is 2 h 06 min at the quickest height in today's winds (24,000 ft, a 20-knot tailwind), arriving about 9:34 pm CDT (02:34 UTC), after sunset at the destination. 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: 4 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 4 forecast points nearest it (CMH, CVG, LOU, BNA). 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.
