St Marys Muni (KOYM) sits in St Marys, Pennsylvania. The field elevation is 1,934.3 ft MSL. It has one runway, 10/28, which is 4,300 ft long with an asphalt surface. There is no control tower. CTAF and UNICOM are both 122.7.
The airport has one ILS approach on runway 28. Published remarks say the medium intensity approach lighting system for runway 28 is activated on the CTAF. The precision approach path indicators for runways 10 and 28 are also activated on the CTAF. The PAPI on both ends has a limited usable sector, so check your alignment early on final. The field is a cold temperature airport. Altitude correction is required at or below minus 36 degrees Celsius.
Pattern altitude is not published. Use the standard 1,000 ft AGL for light piston traffic unless the current FAA Chart Supplement says otherwise. That puts the pattern at about 2,934 ft MSL based on the listed field elevation. St. Marys Municipal Airport is on the field. It carries 100LL and Jet A with Prist. The airport also has runway edge lighting and approach lighting on runway 28. Watch the published fence and road obstructions near both runway ends. This is a high-elevation field, so performance planning matters on warm days.
