San Diego International to John Glenn Columbus International SAN → CMH

1,703 nautical miles (1,960 statute miles) northeast on a straight line, true course 065°, about 054° magnetic at the departure end (variation 11E). At 120 knots that is 10 h 01 min at the quickest height in today's winds (34,000 ft, a 50-knot tailwind), arriving about 6:32 am EDT (10:32 UTC), after sunset at the destination. Right now SAN is VFR, wind from the west-southwest (250°) at 6 knots; CMH is marginal VFR, wind from the north-northwest (340°) at 9 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: 386 flights in the DOT's last twelve reported months, the route's page.

The eastbound cruising heights for this course (VFR: odd thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 17 forecast points nearest it (SAN, BLH, PRC, FMN, ABQ, ALS, PUB, GCK, ICT, SLN, MKC, COU, STL, SPI, IND, CVG, CMH). A plus sign is a headwind, a minus sign a tailwind.

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.
