St Mary's Airport (PASM/KSM) serves the community of St Mary's in western Alaska, on the lower Yukon River near its delta. It offers a long, lit primary runway with an ILS approach alongside a shorter crosswind strip, making it a useful stop for pilots operating in the Yukon-Kuskokwim Delta region.
St Mary's Airport, identified by the ICAO code PASM and IATA code KSM, is a small airport at St Mary's, Alaska, in the Yukon-Kuskokwim Delta region of the state's remote west coast. It handles scheduled airline service into the community as well as general aviation traffic, and its combination of a long paved instrument runway and a shorter crosswind strip makes it a practical waypoint for pilots flying the bush routes of western Alaska.
The airport sits at an elevation of 305 feet and lies within the broad, largely uncontrolled airspace typical of rural western Alaska. Traffic in the area is coordinated through Anchorage Center on 124 MHz, with Kenai Radio providing flight service on 122.35 MHz.
St Mary's has two physical runways. The main runway, 17/35, is 6,414 feet long with a hard surface, is lit, and is served by an ILS approach to runway 17. The secondary runway, 06/24, is shorter at 1,731 feet, also with a hard surface, but is unlit.
Airport weather is broadcast on the AWOS-3 frequency of 128.7 MHz. The common traffic advisory frequency (CTAF) is 122.3 MHz, and Kenai Radio flight service can be reached on 122.35 MHz. Anchorage Center handles en-route traffic on 124 MHz, and a TWEB broadcast is noted on 23 MHz. An ILS approach is available to runway 17, reflecting the field's role as an instrument-capable airport for the surrounding region.
St Mary's Airport continues to support scheduled airline service to the community of St Mary's along with general aviation activity, and its longer runway is equipped with an ILS approach for instrument operations.
