GATEWAY TRACON LETTER TO AIRMEN

Gateway Terminal Radar Approach Control (TRACON) will continue to provide radar vectors
and separation service for practice instrument approaches for the Spirit of S1.Louis (SUS), S1.
Louis Regional (ALN), S1.Louis Downtown-Parks (CPS), and Scott Air Force Base/MidAmerica
(BLV) Airports.

This additional service is being provided for the purpose of achieving added safety through more
organized and controlled operations in terminal areas where practice instrument approaches are
conducted. VFR aircraft making simulated instrument approaches are expected to remain in
VFR conditions throughout the approach procedure. The controller will also include an
instruction "MAINTAIN VFR."

Unless otherwise instructed by ATC the following frequencies are to be used:
SUS--126.5 MHz (VHF) or 254.3 MHz (UHF)
ALN--124.2 MHz (VHF) or 353.9 MHz (UHF)
CPS--123.7 MHz (VHF) or 371.87 MHz (UHF)
BLV--125.2 MHz (VHF) or 281.5 MHz (UHF)

After establishing radio contact with S1.Louis Approach Control, advise the controller which
approach you wish to execute, and what your intentions are upon completion of the approach,
(e.g., full-stop landing, stay in the pattern, etc.)

Further and more complete information pertaining to this subject may be found in the
Aeronautical Iriformation Manual, Official Guide to Basic Flight Information, and ATC
Procedures.
