Hybrid Approaches

Perhaps you call them “Frankenstein” approaches since these require both RNAV (GPS) and conventional navigation, grabbing pieces from each.

Key Takeaways:

The ILS or LOC RWY 21 approach at Stevens Point (KSTE) is a "hybrid" procedure, uniquely integrating traditional ILS guidance with essential GPS navigation for initial approach fixes (IAFs) and the missed approach, and features an RNAV-style Terminal Arrival Area (TAA).
This integration of GPS into traditional ILS approaches reflects an FAA-acknowledged trend towards more common hybrid procedures as legacy VOR navigation aids are phased out from the National Airspace System.
While a parallel RNAV (GPS) RWY 21 approach exists, the ILS can offer slightly lower decision minimums for non-WAAS GPS aircraft, though it is not authorized for alternate airport planning due to not being monitored.
Pilots are recommended to utilize GPS for precision navigation to IAFs due to approach services being provided by Minneapolis Center, and should be aware of nearby Minimum Operational Network (MON) airports for contingency during GPS outages.

Stevens Point is located approximately in the middle of Wisconsin, along the Wisconsin River, which loggers used to transport logs on the way to market. The city dates back to the mid-1800s and was named after George Stevens, who owned a grocery and general store that served the logging community.

Stevens Point Municipal Airport (KSTE) is about three miles northeast of the city’s central business district. It is recognized by the FAA as part of the National Plan of Integrated Airport Systems for 2021-2025, thereby categorizing it as a regional general aviation facility. This allows the airport to receive federal grants under the Airport Improvement Program.
