The ILS has published minimums of 200-foot ceilings with 3/4 mile visibility to accomodate Category A, B, C, D, and E aircraft. The TACAN system, located on the airfield, permits suitably equipped aircraft to land at minimums of 500-foot ceilings, with 1 1/4 mile visability.

A back-course ILS approach utilizing the Cash NDB, provides a non-recision approach to Runway 35, with published minimums of:

• 900-foot ceiling, with a local altimeter setting for one mile visibility for Category A, B, and C aircraft
• 900-foot ceiling and 1 1/4 mile visibility for Category D and E aircraft
