Start Preamble


Federal Aviation Administration (FAA), DOT.


Request for public comment.


The Federal Aviation Administration is requesting public comment on a proposal to change the monitor status of select air navigational aids (NAVAIDS) at airports in the United States. The FAA is proposing that certain Instrument Landing Systems (ILS), Localizer Type Directional Aids (LDA), Microwave Landing Systems (MLS), and Non-Directional Beacons (NDB) become unmonitored.

The ILS NAVAIDS at the following airports are proposed to become unmonitored during the times that the control tower is closed. The associated ILS approaches for these airports are either not authorized for alternate airport filing purposes when the control tower is closed or the airport activity is low when the control tower is closed:

(1) Florence, South Carolina (FLO), ILS, Runway 9. (2) Joplin, Missouri (JLN), ILS, Runways 13 and 18. (3) Macon, Georgia (MCN), ILS, Runway 5. (4) Manhattan, Kansas (MHK), ILS, Runway 3. (5) Mobile, Alabama (MOB), ILS, Runways 14 and 32. (6) Missoula, Montana (MSO), ILS, Runway 11. (7) North Myrtle Beach, South Carolina (CRE), ILS, Runway 23. (8) Savannah, Georgia (SAV), ILS, Runways 9 and 36. (9) Tallahassee, Florida (TLH), ILS, Runway 36. (Tallahassee ILS, Runway 27 will not be affected because of its ILS Category II status.) (10) Walla Walla, Washington (ALW), ILS, Runway 20.

The following ILS NAVAIDS are proposed to become unmonitored due to low annual activity at the associated airport:

1) Bemidji, Minnesota (BJI) ILS, Runway 31. (2) Huron, South Dakota (HON), ILS, Runway 12. (3) Hoquiam, Washington (HQM), ILS, Runway 24. (4) International Falls, Minnesota (INL), ILS, Runway 31. (5) Liberal, Kansas (LBL), ILS, Runway 35. (6) Muscle Shoals, Alabama (MSL), ILS, Runway 29. (7) Norfolk, Nebraska (OFK), ILS, Runway 1.

The following NAVAIDS associated with non-precision approaches are proposed to become unmonitored:

(1) Charles City, Iowa (CCY), ILS Localizer, Runway 12. (2) Conrad, Montana (SO1), Conrad (CRD) NDB. (3) Elkins, West Virginia (EKN), LDA/DME. (4) Elko, Nevada (EKO), LDA/DME, Runway 23. (5) Miles City, Montana (MLS), Horton (HTN) NDB. (6) Mountain Home Municipal, Idaho (U76), Sturgeon (STI) NDB. (7) Ontario, Oregon (ONO), Ontario (ONO) NDB. (8) Pullman/Moscow ID, Washington (PUW), MLS. (9) Rawlins, Wyoming (RWL), Sinclair (SIR) NDB. (10) Wenatchee, Washington (EAT), MLS.
