1、235 Federal Communications Commission Pt. 90 (c) Only one AWOS, ASOS, or ATIS will be licensed at an airport. 53 FR 28940, Aug. 1, 1988, as amended at 64 FR 27476, May 20, 1999 87.529 Frequencies. Prior to submitting an application, each applicant must notify the applica-ble FAA Regional Frequency M
2、anage-ment Office. Each application must be accompanied by a statement showing the name of the FAA Regional Office and date notified. The Commission will assign the frequency. Normally, fre-quencies available for air traffic con-trol operations set forth in subpart E will be assigned to an AWOS, ASO
3、S, or to an ATIS. When a licensee has en-tered into an agreement with the FAA to operate the same station as both an AWOS and as an ATIS, or as an ASOS and an ATIS, the same frequency will be used in both modes of operation. 69 FR 52886, June 14, 2004 PART 90PRIVATE LAND MOBILE RADIO SERVICES Subpar
