Piedmont Triad International to Greater Kankakee Airport GSO → IKK
476 nautical miles (548 statute miles) northwest on a straight line, true course 311°, about 319° magnetic at the departure end (variation 8W). At 120 knots that is 4 h 29 min at the quickest height in today's winds (4,500 ft, a 14-knot headwind), arriving about 12:17 am CDT (05:17 UTC), after sunset at the destination. Right now GSO is VFR, wind from the southwest (230°) at 7 knots; IKK is VFR, wind from the southeast (130°) 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 5 forecast points nearest it (ROA, CRW, CVG, IND, JOT). 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.
