RWY 27

Union County Airport sits in Marysville, Ohio. Field elevation is 1,020.7 ft MSL. It has two runways. The longest is 09/27 at 4,218 ft asphalt. The other runway is 08/26 at 2,522 ft turf. This is an untowered field. CTAF and UNICOM are both 123.05. Columbus Approach is listed for approach and departure work on 125.95 and 317.775. No ILS approaches are published here.

Pattern altitude is not published. Use the current FAA Chart Supplement before flying the pattern. SkyVista Aviation is on the field. It carries 100LL, Jet A and Jet A Prist. 100LL is available 24 hours self-serve by credit card.

There are a few operational notes to keep in mind. Runway 27 has a displaced threshold issue tied to a railroad obstacle on the approach side. The Chart Supplement says to check NOTAMs for the aerobatic box south of the field. Right traffic is recommended for runway 27 and runway 26 when that activity is in play. Runway 26 and runway 08 use cone markings at the threshold and edges. Wildlife is also a factor here, so expect deer and birds on or near the airport. For clearance delivery, Columbus Approach is the contact listed in the remarks.
