  • the frequencies that the FAA selects. Although both the FAA and SAMA requested that four frequencies be designated for the FIS, ARINC/ATA argues that specific FIS frequencies need not be listed in our Rules. In this connection, ARINC contends that FIS could be implemented in the 136-136.475 MHz band by adding FIS to footnote US244 and modifying 47 C.F.R. § 87.137 to include the 14K0G1D emission designator. NBAA also states that further FIS studies by RTCA, Inc., should be completed and its recommendations considered before decisions are made regarding specific applications on assigned channels. In further comments, ARINC clarifies that although the FAA will make three of the ATC channels available for FIS and ARINC will make one of the AOC

Furthermore, we note that the current system of granting certification of dual spacing transceivers on an individual, case-by-case basis creates an administrative workload for both the regulated community and our own staff. Accordingly, in the interest of air safety and operational efficiency, we now propose to amend Section 87.137 of our Rules to permit certification of dual channel spacing transceivers to accommodate aircraft which operate in countries that employ 8.33 kHz spacing. We note that this proposal addresses equipment certification only. Since, at this time, the FAA has not adopted 8.33 kHz channel spacing within the United States, we do not propose to permit the use of 8.33 kHz
