FEDERAL COMMUNICATIONS COMMISSION

47 CFR Part 87

[WT Docket Nos. 10-61 and 09-42, RM-11503, RM-11596; FCC 13-30]


Aviation Services

AGENCY: Federal Communications Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: In this document, the Federal Communications Commission 
(Commission) amends its rules to authorize the use of frequency 1090 
MHz by aeronautical utility mobile stations for airport surface 
detection equipment, commonly referred to as vehicle ``squitters,'' to 
help reduce collisions between aircraft and airport ground vehicles. In 
addition, we establish service rules for audio visual warning systems 
to help aircraft in flight avoid antenna structures and other 
obstacles. We also adopt rules to permit ground testing of aviation 
data link systems, and decline to authorize remote monitoring of 
certain automated ground stations.

DATES: Effective November 4, 2013. The incorporation by reference of 
certain publications listed in the rule is approved by the Director of 
the Federal Register as of November 4, 2013.

FOR FURTHER INFORMATION CONTACT: Tim Maguire, Mobility Division, 
Wireless Telecommunications Bureau at (202) 418-2155.

SUPPLEMENTARY INFORMATION: This is a summary of the Commission's Report 
and Order (R&O), in WT Docket No. 10-61; FCC 13-30, adopted February 
28, 2013, and released March 1, 2013. The full text of this document is

Background

    1. Air traffic controllers utilize airport surface detection 
equipment (ASDE-X) to manage the movement of aircraft on airport 
surfaces, but the current system does not allow the positive 
identification of ground vehicles such as snowplows and maintenance 
vehicles that routinely operate on the runway movement area. See 47 CFR 
87.345. Unless the vehicle is visible from the control tower, air 
traffic controllers can determine only its location, but not the 
vehicle type or the operator. See NPRM, 25 FCC Rcd at 3356 para. 3. In 
response to growing concerns about airplanes colliding with or having 
to take evasive maneuvers to avoid vehicles on the airport surface, the 
Federal Aviation Administration (FAA) seeks to expand the use of ASDE-X 
to manage the movement of service vehicles as well as aircraft in the 
runway movement area.
    2. The National Telecommunications and Information Administration 
(NTIA), supported by the FAA, filed a petition for rulemaking 
requesting that the Commission amend part 87 of the Commission's rules 
to allow use of frequency 1090 MHz for tracking of ground vehicle 
movements on the airport surface. See Petition for Rulemaking of the 
National Telecommunications and Information Administration (July 29, 
2008). In the Notice of Proposed Rulemaking and Order (NPRM), the 
Commission noted that the frequency 1090 MHz is currently used for 
ASDE-X to manage the movement of aircraft on airport surfaces and for 
other things, such as the Traffic Alert and Collision Avoidance System 
(TCAS),\1\ but tentatively concluded that permitting use of the 
frequency by vehicle squitters would further the public interest. See 
NPRM, 25 FCC Rcd at 3356 paras. 6-7.
---------------------------------------------------------------------------

    \1\ TCAS is an airborne warning system designed to avert mid-air 
collisions. See Review of part 87 of the Commission's Rules 
Concerning the Aviation Radio Service, Report and Order and Further 
Notice of Proposed Rule Making, WT Docket No. 01-289, 18 FCC Rcd 
21432, 21467 n.265 (2003) (Part 87 Report and Order). In the Part 87 
Report and Order, the Commission adopted a proposal to permit ground 
testing of TCAS on frequency 1090 MHz, and amended Sec.  
87.475(c)(2) of the rules, 47 CFR 87.475(c)(2), accordingly. See 
Part 87 Report and Order, 18 FCC Rcd at 21467 para. 74. When it 
amended Sec.  87.475(c)(2) later in that proceeding, however, the 
Commission inadvertently removed the language authorizing ground 
testing of TCAS on 1090 MHz. See Review of Part 87 of the 
Commission's Rules Concerning the Aviation Radio Service, Second 
Report and Order and Second Further Notice of Proposed Rule Making, 
WT Docket No. 01-289, 21 FCC Rcd 11582, 11587-88 para. 6 (2006) 
(Part 87 Second Report and Order). In the NPRM in this proceeding, 
the Commission proposed to correct that error by amending Sec.  
87.475(c)(2) to restore the deleted language. See NPRM, 25 FCC Rcd 
at 3357 n.13. We now adopt the proposed correction.
---------------------------------------------------------------------------

    3. Accordingly, the Commission sought comment on proposed technical 
and service rules for vehicle squitters on frequency 1090 MHz. See 
NPRM, 25 FCC Rcd at 3357 paras. 9-14. The NPRM sought comment on 
whether the Commission should limit operation of vehicle squitters to 
the runway movement area to prevent use of the system for purposes 
other than vehicle and aircraft safety (such as tracking baggage 
carts). See NPRM, 25 FCC Rcd at 3357 paras. 12. The NPRM also 
tentatively agreed with NTIA's proposal that the Commission coordinate 
applications with the FAA through the Interdepartment Radio Advisory 
Committee (IRAC), and it sought comment on whether the Commission 
should require applicants to pre-coordinate with the relevant FAA 
Regional Office before filing an application with the Commission. See 
NPRM, 25 FCC Rcd at 3357 para. 13.

I. Procedural Matters

A. Paperwork Reduction Act Analysis

    4. This document contains new or modified information collection 
requirements subject to the Paperwork Reduction Act of 1995 (PRA), 
Public Law 104-13. Specifically, it requires prospective DLT station 
licensees to coordinate their applications with ASRI, the aeronautical 
enroute station

[[Page 61204]]

licensee. It will be submitted to the Office of Management and Budget 
(OMB) for review under section 3507(d) of the PRA. OMB, the general 
public, and other Federal agencies are invited to comment on the new or 
modified information collection requirements contained in this 
proceeding. In the present document, we have assessed the effects of 
requiring coordination of DLT applications with ASRI and find that this 
will avoid interference to safety-related aeronautical enroute 
communications without having a significant impact on small business 
concerns with fewer than 25 employees. Coordination with ASRI should 
not be more burdensome than coordination with the FAA, which is 
required for analogous RLT applications.

B. Report to Congress

    5. The Commission will send a copy of the R&O to Congress and the 
Government Accountability Office pursuant to the Congressional Review 
Act, see 5 U.S.C. 801(a)(1)(A).

C. Final Regulatory Flexibility Analysis

    6. As required by the Regulatory Flexibility Act of 1980, as 
amended (RFA), an Initial Regulatory Flexibility Analysis (IRFA) was 
incorporated in the NPRM in WT Docket Nos. 10-61 and 09-42; RM-11503 
and RM-11596, at 75 FR 22352, April 28, 2010. The Commission sought 
written public comment on the proposals in the NPRM, including comment 
on the IRFA. This present Final Regulatory Flexibility Analysis (FRFA) 
conforms to the RFA.
Need for, and Objectives of, the Report and Order
    7. The rules adopted in the R&O are intended to ensure that the 
Commission's part 87 rules governing the Aviation Radio Service remain 
up to date and continue to further the Commission's goals of 
accommodating new technologies, facilitating the efficient and 
effective use of the aeronautical spectrum, avoiding unnecessary 
regulation, and, above all, enhancing the safety of flight. 
Specifically, we amend part 87 of the Commission's rules to allow use 
of the frequency 1090 MHz by aeronautical utility mobile stations for 
airport surface detection equipment, commonly referred to as vehicle 
``squitters,'' to help reduce collisions between aircraft and airport 
ground vehicles. In addition, we establish service rules for audio 
visual warning systems to help aircraft in flight avoid antenna 
structures and other obstacles. We also adopt rules to permit ground 
testing of aviation data link test systems.
Summary of Significant Issues Raised by Public Comments in Response to 
the IRFA
    8. No comments were submitted specifically in response to the 
IRFAs. Nonetheless, we have considered the potential economic impact on 
small entities of the rules discussed in the IRFAs, and we have 
considered alternatives that would reduce the potential economic impact 
on small entities of the rules enacted herein.
Description and Estimate of the Number of Small Entities to Which Rules 
Will Apply
    9. The RFA directs agencies to provide a description of, and, where 
feasible, an estimate of the number of small entities that may be 
affected by the rules adopted herein. The RFA 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: (1) Is independently owned and operated; 
(2) is not dominant in its field of operation; and (3) satisfies any 
additional criteria established by the Small Business Administration 
(SBA).
    10. Small businesses in the aviation and marine radio services use 
a marine very high frequency (VHF), medium frequency (MF), or high 
frequency (HF) radio, any type of emergency position indicating radio 
beacon (EPIRB) and/or radar, an aircraft radio, and/or any type of 
emergency locator transmitter (ELT). The Commission has not developed a 
definition of small entities specifically applicable to these small 
businesses. For purposes of this analysis, the Commission uses the SBA 
small business size standard for the category Wireless 
Telecommunications Carriers (except satellite),'' which is 1,500 or 
fewer employees. Census data for 2007 shows that there were 1,383 firms 
in that category that operated for the entire year. Of those 1,383, 
1,368 had fewer than 1,000 employees, and 15 firms had 1,000 or more 
employees. Thus under this category and the associated small business 
size standard, the majority of firms can be considered small.
    11. Some of the rules adopted herein may also affect small 
businesses that manufacture aviation radio equipment. The Census Bureau 
does not have a category specific to aviation radio equipment 
manufacturers. The appropriate category is that for wireless 
communications equipment manufacturers. The Census Bureau defines this 
category as follows: ``This industry comprises establishments primarily 
engaged in manufacturing radio and television broadcast and wireless 
communications equipment. Examples of products made by these 
establishments are: Transmitting and receiving antennas, cable 
television equipment, GPS equipment, pagers, cellular phones, mobile 
communications equipment, and radio and television studio and 
broadcasting equipment.'' The SBA has developed a small business size 
standard for Radio and Television Broadcasting and Wireless 
Communications Equipment Manufacturing, which is: All such firms having 
750 or fewer employees. According to Census bureau data for 2007, there 
were a total of 939 firms in this category that operated that year. Of 
this total, 912 had fewer than 500 employees and 27 had 500 or more 
employees. Thus, under this size standard, the majority of firms can be 
considered small.
Description of Projected Reporting, Recordkeeping, and Other Compliance 
Requirements for Small Entities
    12. The rule changes adopted in the R&O require manufacturers to 
meet certain criteria and potential licensees to operate the equipment 
as prescribed in the Rules, including prior coordination with the FAA 
and ASRI. We believe the other final rules will have no significant 
effect on the compliance burdens of regulatees. The R&O requires data 
link test (DLT) system applicants to coordinate with the aeronautical 
enroute licensee for the frequencies on which the DLT applicant 
proposes to operate. This requirement affects small and large companies 
equally. The compliance requirement is no greater than the requirement 
to coordinate with the Federal Aviation Administration applications to 
operate analogous radionavigation land test system equipment, which the 
NPRM proposed to extend to DLT applicants.
Steps Taken To Minimize the Significant Economic Impact on Small 
Entities, and Significant Alternatives Considered
    13. The RFA requires an agency to describe the steps it has taken 
to minimize the significant economic impact on small entities 
consistent with the stated objectives of applicable statutes, including 
a statement of the factual, policy, and legal reasons for selecting the 
alternative adopted in the final rule and why each one of the other 
significant alternatives to the rule considered by the agency which 
affect

[[Page 61205]]

the impact on small entities was rejected.
    14. We believe that the R&O does not impose any significant 
additional reporting, recordkeeping, or other compliance requirements 
on small entities. The rules adopted in the R&O authorize new ground 
station technologies that will promote the overriding issue of aviation 
safety. No commenter identified any less burdensome alternatives that 
would be consistent with the item's objectives and the Commission's 
goals and responsibilities.
    15. The Commission will send a copy of the R&O in WT Docket Nos. 
10-61 and 09-42, including the Final Regulatory Flexibility Analysis, 
in a report to be sent to Congress pursuant to the Congressional Review 
Act. In addition, the Commission will send a copy of the R&O, including 
the Final Regulatory Flexibility Analysis, to the Chief Counsel for 
Advocacy of the SBA. A copy of the R&O and the Final Regulatory 
Flexibility Analysis (or summaries thereof) will also be published in 
the Federal Register.

12. Section 87.483 is added to subpart Q to read as follows:


Sec.  87.483  Audio visual warning systems.

    An audio visual warning system (AVWS) is a radar-based obstacle 
avoidance system. AVWS activates obstruction lighting and transmits VHF 
audible warnings to alert pilots of potential collisions with land-
based obstructions. The AVWS operations are limited to locations where 
natural and man-made obstructions exist. The continuously operating 
radar calculates the location, direction and groundspeed of nearby 
aircraft that enter one of two warning zones reasonably established by 
the licensee. As aircraft enter the first warning zone, the AVWS 
activates obstruction lighting. If the aircraft continues toward the 
obstacle and enters the second warning zone, the VHF radio transmits an 
audible warning describing the obstacle.
    (a) Radiodetermination (radar) frequencies. Frequencies authorized 
under Sec.  87.475(b)(8) of this chapter are available for use by an 
AVWS. The frequency coordination requirements in Sec.  87.475(a) of 
this chapter apply.
    (b) VHF audible warning frequencies. Frequencies authorized under 
Sec.  87.187(j), Sec.  87.217(a), Sec.  87.241(b), and Sec.  87.323(b) 
(excluding 121.950 MHz) of this chapter are available for use by an 
AVWS. Multiple frequencies may be authorized for an individual station, 
depending on need and the use of frequencies assigned in the vicinity 
of a proposed AVWS facility. Use of these frequencies is subject to the 
following limitations:
    (1) The output power shall not exceed -3 dBm watts for each 
frequency authorized.
    (2) The antenna used in transmitting the audible warnings must be 
omnidirectional with a maximum gain equal to or lower than a half-wave 
centerfed dipole above 30 degrees elevation, and a maximum gain of +5 
dBi from horizontal up to 30 degrees elevation.
    (3) The audible warning shall not exceed two seconds in duration. 
No more than six audible warnings may be transmitted in a single 
transmit cycle, which shall not exceed 12 seconds in duration. An 
interval of at least twenty seconds must occur between transmit cycles.
