1. In the Report and Order, the FCC adopts changes to part 87 of the Commission's rules that were either proposed in or suggested in response to the Notice of Proposed Rule Making (“NPRM”) in this proceeding. The NPRM, released on October 16, 2001, 66 FR 64785 (December 14, 2001), proposed rule changes that were intended to consolidate, revise and streamline our rules governing aviation communications. These changes were proposed to ensure that the part 87 rules reflect recent technological advances and are consistent with other Commission rules. In addition, changes were proposed to eliminate regulations that are duplicative, outmoded, or otherwise unnecessary in the Aviation Radio Service.
2. The significant actions taken in this Report and Order are as follows: (i) Updating the technical specifications for Aeronautical Mobile Satellite (Route) Service (AMS(R)S) equipment; (ii) permitting certification of dual spacing transceivers to accommodate aircraft operating in countries that employ 8.33 kHz channel spacing; (iii) extending license terms of non-aircraft stations from five to ten years; (iv) extending the construction period for aeronautical advisory stations (unicoms) and radionavigation land station from eight months to one year; (v) eliminating all references to the Civil Air Patrol from part 87; (vi) authorizing use of the Differential Global Positioning System (DGPS) in the 108-117.975 MHz and 1559-1610 MHz bands on a non-developmental basis, while also requiring DGPS receivers to meet minimum interference immunity requirements; (vii) modifying the licensing procedures and eligibility requirements for unicoms; and (viii) retaining the rule specifying that there may be only one aeronautical enroute station licensee per location, while clarifying that the licensee is expected to provide access to the spectrum on a reasonable, nondiscriminatory basis.
3. The Report and Order does not contain any new or modified information collection.
4. The Regulatory Flexibility Act of 1980, as amended (RFA), requires that a regulatory flexibility analysis be prepared for notice-and-comment rule making proceedings, unless the agency certifies that “the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities.” The RFA generally defines the term “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction.”
In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act. A “small business concern” is one which: (i) Is independently owned and operated; (ii) is not dominant in its field of operation; and (iii) satisfies any additional criteria established by the SBA.
5. The purpose of the Report and Order is to streamline and update our part 87 rules governing the Aviation Radio Service. We believe that the rules adopted in the Report and Order do not impose any additional compliance burden on small entities.
6. We have identified those small entities that could conceivably be affected by the rule changes adopted herein. Small businesses in the aviation and marine radio services use a marine very high frequency (VHF) radio, any type of emergency position indicating radio beacon (EPIRB) and/or radar, a VHF aircraft radio, and/or any type of emergency locator transmitter (ELT). The adopted rules may also affect small businesses that manufacture radio equipment. However, we anticipate that these rule changes will not impose any new burdens on small entities, but in fact will reduce regulatory and procedural burdens on small entities. The general effect of the rule changes adopted herein is to streamline the rules, remove duplicative requirements, provide greater operational flexibility, promote spectrum efficiency, facilitate equipment certification, and make our rules consistent with international requirements, all of which are measures that should have an overall beneficial effect on the regulated entities. We certified in the Notice of Proposed Rule Making in this proceeding that the rules proposed therein would not, if promulgated, have a significant economic impact upon a substantial number of small entities, as that term is defined by the RFA, and no party has challenged or otherwise commented on that certification.
7. We therefore certify that the requirements of the Report and Order will not have a significant economic impact upon a substantial number of small entities, as that term is defined by the RFA.
8. The Commission will send a copy of the Report and Order, including a copy of this final certification, in a report to Congress pursuant to the Congressional Review Act. In addition, the Report and Order and this final certification will be sent to the Chief Counsel for Advocacy of the Small Business Administration.
9. The Commission's Consumer Information Bureau, Reference Information Center, shall send a copy of this Report and Order including the Regulatory Flexibility Certification and to the Chief Counsel for Advocacy of the Small Business Administration.
For the reasons discussed in the preamble, the Federal Communications Commission amends 47 CFR parts 2, 87 and 95 as follows:

(f) Certification may be requested for equipment that has the capability to transmit in the 138-144 MHz, 148-149.9 MHz, or 150.5-150.8 MHz bands as well as frequency bands set forth in § 87.173. The Commission will only certify this equipment for use in the bands regulated by this part.
16. Section 87.151 is added to read as follows:
§ 87.151
Special requirements for differential GPS receivers.
(a) The receiver shall achieve a message failure rate less than or equal to one failed message per 1000 full-length (222 bytes) application data messages, while operating over a range from −87 dBm to −1 dBm, provided that the variation in the average received signal power between successive bursts in a given time slot shall not exceed 40 dB. Failed messages include those lost by the VHF data receiver system or which do not pass the cyclic redundancy check (CRC) after application of the forward error correction (FEC).
(b) The aircraft receiving antenna can be horizontally or vertically polarized. Due to the difference in the signal strength of horizontally and vertically polarized components of the broadcast signal, the total aircraft implementation loss is limited to 15 dB for horizontally polarized receiving antennas and 11 dB for vertically polarized receiving antennas.
(c) Desensitization. The receiver shall meet the requirements specified in paragraph (a) of this section in the presence of VHF-FM broadcast signals in accord with following tables.
(1) Maximum levels of undesired signals.

(d) Intermodulation Immunity. The receiver shall meet the requirements specified in paragraph (a) of this section in the presence of interference from two-signal, third order intermodulation products of two VHF-FM broadcast signals having levels in accordance with the following:
(1) 2N1 + N2 + 72 ≤ 0 for VHF-FM sound broadcasting signals in the range 107.7-108 MHz; and
(2) 2N1 + N2 + 3 (24 −20log delta f/0.4) ≤ 0 for VHF-FM sound broadcasting signals below 107.7 MHz, where the frequencies of the two VHF-FM sound broadcasting signals produce, within the receiver, a two signal, third-order intermodulation product on the desired VDB frequency.
(3) In the formulas in paragraphs (d)(1) and (d)(2) of this section, N1 and N2 are the levels (dBm) of the two VHF FM sound broadcasting signals at the VHF data broadcast (VDB) receiver input. Neither level shall exceed the desensitization criteria set forth in paragraph (c) of this section. Delta f = 108.1 − f1, where f1 is the frequency of N1, the VHF FM sound broadcasting signal closer to 108.1 MHz.
17. Section 87.169 is revised to read as follows:
§ 87.169
This subpart contains class of station symbols and a frequency table which lists assignable frequencies. Frequencies in the Aviation Services will transmit communications for the safe, expeditious, and economic operation of aircraft and the protection of life and property in the air.

21. Section 87.189 is amended by revising paragraph (c) to read as follows:
§ 87.189
Requirements for public correspondence equipment and operations.
(c) A continuous watch must be maintained on the frequencies used for safety and regularity of flight while public correspondence communications are being handled. For aircraft earth stations, this requirement is satisfied by compliance with the priority and preemptive access requirements of § 87.187(q).
22. Section 87.195 is amended by revising paragraph (a) to read as follows:
§ 87.195
(a) ELTs transmit on the frequency 121.500 MHz, using A3E, A3X or NON Start Printed Page 32885emission. ELTs that transmit on the frequency 406.0-406.1 MHz use G1D emission.
23. Section 87.199 is revised to read as follows:
§ 87.199
Special requirements for 406.0-406.1 MHz ELTs.
(a) Except for the spurious emission limits specified in § 87.139(h), 406.0-406.1 MHz ELTs must meet all the technical and performance standards contained in the Radio Technical Commission for Aeronautics document titled “Minimum Operational Performance Standards 406 MHz Emergency Locator Transmitters (ELT)” Document No. RTCA/DO-204 dated September 29, 1989. This RTCA document is incorporated by reference in accordance with 5 U.S.C. 552(a), and 1 CFR part 51. Copies of the document are available and may be obtained from the Radio Technical Commission of Aeronautics, One McPherson Square, 1425 K Street NW., Washington, DC 20005. The document is available for inspection at Commission headquarters at 445 12th Street, SW., Washington, DC 20554. Copies may also be inspected at the Office of the Federal Register, 800 North Capital Street NW., suite 700, Washington, DC.
(b) The 406.0-406.1 MHz ELT must contain as an integral part a homing beacon operating only on 121.500 MHz that meets all the requirements described in the RTCA Recommended Standards document described in paragraph (a) of this section. The 121.500 MHz homing beacon must have a continuous duty cycle that may be interrupted during the transmission of the 406.0-406.1 MHz signal only.
(c) Prior to verification of a 406.0-406.1 MHz ELT, the ELT must be certified by a test facility recognized by one of the COSPAS/SARSAT Partners that the equipment satisfies the design characteristics associated with the COSPAS/SARSAT document COSPAS/SARSAT 406 MHz Distress Beacon Type Approval Standard (C/S T.007). Additionally, an independent test facility must certify that the ELT complies with the electrical and environmental standards associated with the RTCA Recommended Standards.
(d) The procedures for verification are contained in subpart J of part 2 of this chapter.
(e) An identification code, issued by the National Oceanic and Atmospheric Administration (NOAA), the United States Program Manager for the 406.0-406.1 MHz COSPAS/SARSAT satellite system, must be programmed in each ELT unit to establish a unique identification for each ELT station. With each marketable ELT unit the manufacturer or grantee must include a postage pre-paid registration card printed with the ELT identification code addressed to: NOAA/SARSAT Beacon Registration, E/SP3, Federal Building 4, Room 3320, 5200 Auth Road, Suitland, MD 20746-4304. The registration card must request the owner's name, address, telephone, type of aircraft, alternate emergency contact, and other information as required by NOAA. The registration card must also contain information regarding the availability to register the ELT at NOAA's online Web-based registration database at: http://www.beaconregistration.noaa.gov. Further, the following statement must be included: “WARNING “ Failure to register this ELT with NOAA before installation could result in a monetary forfeiture being issued to the owner.”
(f) To enhance protection of life and property, it is mandatory that each 406.0-406.1 MHz ELT must be registered with NOAA before installation and that information be kept up-to-date. In addition to the identification plate or label requirements contained in §§ 2.925 and 2.926 of this chapter, each 406.0-406.1 MHz ELT must be provided on the outside with a clearly discernable permanent plate or label containing the following statement: “The owner of this 406.0-406.1 MHz ELT must register the NOAA identification code contained on this label with the National Oceanic and Atmospheric Administration (NOAA), whose address is: NOAA/SARSAT Beacon Registration, E/SP3, Federal Building 4, Room 3320, 5200 Auth Road, Suitland, MD 20746-4304.” Aircraft owners shall advise NOAA in writing upon change of aircraft or ELT ownership, or any other change in registration information. Fleet operators must notify NOAA upon transfer of ELT to another aircraft outside of the owner's control, or an other change in registration information. NOAA will provide registrants with proof of registration and change of registration postcards.
(g) For 406.0-406.1 MHz ELTs whose identification code can be changed after manufacture, the identification code shown on the plant or label must be easily replaceable using commonly available tools.
24. Section 87.215 is amended by redesignating paragraphs (c) and (d) as paragraphs (f) and (g), adding new paragraphs (c), (d), and (e), and by removing the Effective Date Note to read as follows:
§ 87.215
Supplemental eligibility.
(c) At an airport where only one unicom may be licensed, eligibility for new unicom licenses is restricted to State or local government entities, and to nongovernmental organizations (NGOs) that are authorized to apply for the license by a State or local government entity whose primary mission is the provision of public safety services. All applications submitted by NGOs must be accompanied by a new, written certification of support (for the NGO applicant to operate the applied for station) by the state or local government entity. Applications for a unicom license at the same airport, where only one unicom may be licensed, that are filed by two or more applicants meeting these eligibility criteria must be resolved through settlement or technical amendment.
(d) At an airport where only one unicom may be licensed, the license may be assigned or transferred only to an entity meeting the requirements of paragraph (c) of this section.
(e) An applicant for renewal of a unicom license shall be granted a presumptive renewal expectancy regardless of whether the applicant is eligible for a new unicom license under paragraph (c) of this section. Unless the renewal expectancy is defeated, applications that are mutually exclusive with the renewal application will not be accepted. The renewal expectancy may be defeated only upon a determination, following a hearing duly designated on the basis of a petition to deny or on the Commission's own motion, that the renewal applicant has not provided substantial service. For purposes of this paragraph, substantial service means service which is sound, favorable, and substantially above a level of mediocre service during the applicant's past license term. If the renewal expectancy is defeated, the renewal application will be dismissed unless the renewal applicant is eligible for a new unicom license pursuant to paragraph (c) of this section.
25. Section 87.217 is amended by revising paragraph (a) introductory text to read as follows:
§ 87.217
(a) Only one unicom frequency will be assigned at any one airport. Applicants must request a particular frequency, which will be taken into consideration when the assignment is made. The frequencies assignable to unicoms are:
Start Printed Page 32886 Start Amendment Part
26. Section 87.421 is amended by revising paragraph (c) to read as follows:
§ 87.421
(c) Frequencies in the band 121.600-121.925 MHz are available to control towers and RCOs for general air traffic control communications. The antenna heights shall be restricted to the minimum necessary to achieve the required coverage. Channel spacing is 25 kHz.
27. Section 87.475 is amended by revising paragraphs (b)(2) and (c)(2) introductory text to read as follows:
§ 87.475
(2) Radiobeacon stations enable an aircraft station to determine bearing or direction in relation to the radiobeacon station. Radiobeacons operate in the bands 190-285 kHz; 325-435 kHz; 510-525 kHz; and 525-535 kHz. Radiobeacons may be authorized, primarily for off-shore use, in the band 525-535 kHz on a non-interference basis to travelers information stations.
(2) The frequencies available for assignment to radionavigation land test stations for the testing of airborne receiving equipment are 108.000 and 108.050 MHz for VHF omni-range; 108.100 and 108.150 MHz for localizer; 334.550 and 334.700 MHz for glide slope; 978 and 979 MHz (X channel)/1104 MHz (Y channel) for DME; 1030 MHz for air traffic control radar beacon transponders; 1090 MHz for Traffic Alert and Collision Avoidance Systems (TCAS); and 5031.0 MHz for microwave landing systems. Additionally, the frequencies in paragraph (b) of this section may be assigned to radionavigation land test stations after coordination with the FAA. The following conditions apply:
28. Remove and reserve subpart R.
29. Section 87.529 is revised to read as follows:
§ 87.529
Prior to submitting an application, each applicant must notify the applicable FAA Regional Frequency Management 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, frequencies available for air traffic control operations set forth in Subpart E will be assigned to an AWOS, ASOS, or to an ATIS. When a licensee has entered 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.
30. The authority citation for part 95 continues to read as follows:
Authority: Sections 4, 303, 48 Stat. 1066, 1082, as amended; 47 U.S.C. 154, 303.
31. Section 95.655 is amended by revising paragraph (a) to read as follows:
§ 95.655
(a) No transmitter will be certificated for use in the CB service if it is equipped with a frequency capability not listed in § 95.625, and no transmitter will be certificated for use in the GMRS if it is equipped with a frequency capability not listed in § 95.621, unless such transmitter is also certificated for use in another radio service for which the frequency is authorized and for which certification is also required. (Transmitters with frequency capability for the Amateur Radio Services and Military Affiliate Radio System will not be certificated.)
