edge lighting. Both runway ends have runway end identifier lights. Runway 21 is equipped with precision approach path indicators, having replaced the older VASIs. The airport also has an airport beacon, but hills - especially the one to the north - can limit its ability to be viewed. Instrument procedures For many years a circling instrument approach has brought aircraft in from the north via the Binghamton VORTAC, about five miles (8 km) distant. As of Oct 2015 the MDA is above the airport elevation or if the aircraft can identify the CUMOS fix. Visibility required for the approach is 1¼ miles for categories A and B, with categories C and above NA. Some historical procedures in the 1970s required around 1¾ miles visibility as an absolute minimum. With the addition of GPS-based navigation, straight-in RNAV (GPS) approaches were added for runways 3 and 21. These approaches have slightly lower minima than the VOR-A. Aircraft in categories C and above are still NA. For details, check current approach charts. Weather factors Being adjacent to the Susquehanna River, the airport experiences fog on a relatively frequent basis during the late night to mid-morning hours during the late summer to autumn with visibilities often under one-quarter mile.
