THORSON AIRFIELD
ABERDEEN, SD
As a privately owned, non-towered facility, Thorson Airfield (SD05) serves Aberdeen, South Dakota. Its single runway, 17/35, is a turf strip measuring 2,850 feet long and 100 feet wide.
Operations are restricted to visual flight rules, with no published instrument approaches. The strip is non-towered and has no published frequencies, so pilots keep their own separation under see-and-avoid procedures. The field sells 100 avgas. As a private-use facility, it is not open to transient traffic without prior permission.
The field rests at 1,300 feet above mean sea level.
