Use of Automatic Dependent Surveillance--Broadcast (ADS-B) Out in 
Support of Reduced Vertical Separation Minimum (RVSM) Operations

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: This action revises the FAA's requirements for application to 
operate in RVSM airspace. The amendment eliminates the requirement for 
operators to apply for an RVSM authorization when their aircraft are 
equipped with qualified ADS-B Out systems and meet specific altitude 
keeping equipment requirements for operations in RVSM airspace. This 
action recognizes the enhancements in aircraft monitoring resulting 
from the use of ADS-B Out systems and responds to requests from 
operators to eliminate the burden and expense of the current RVSM 
application process for aircraft equipped with qualified ADS-B Out 
systems.

DATES: Effective January 22, 2019.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking

    The FAA's authority to issue rules with respect to aviation safety 
is found in Title 49, United States Code (49 U.S.C.). Sections 106(f), 
40113(a), and 44701(a) authorize the FAA Administrator to prescribe 
regulations necessary for aviation safety. Under Section 40103(b), the 
FAA is charged with prescribing regulations to enhance the efficiency 
of the national airspace. This rulemaking is within the scope of these 
authorities as it removes regulatory requirements that the FAA no 
longer finds necessary for safe operations in RVSM airspace and 
establishes requirements for the use of qualified ADS-B Out systems to 
facilitate operations in that airspace.

I. Overview of Final Rule

    This action amends Appendix G of part 91 of Title 14 of the Code of 
Federal Regulations (14 CFR) to permit an operator of an aircraft 
equipped with a qualified ADS-B Out system meeting altitude keeping 
equipment performance requirements for operations in RVSM airspace to 
operate in that airspace without requiring a specific authorization. 
Under this action, the FAA considers a qualified ADS-B Out system to be 
one that meets

[[Page 65488]]

the requirements of 14 CFR 91.227. The FAA is taking this action based 
on the technological advances provided by ADS-B Out systems. As a 
result of these advances, detailed applications and specific 
authorizations for operators of these aircraft to conduct operations in 
RVSM airspace are no longer necessary. The amendment also removes the 
detailed designations of airspace where revised RVSM may be applied 
that were previously found in Appendix G of part 91.

II. Background

    Vertical separation standards establish the minimum vertical 
distance between aircraft routes in the National Airspace System. In 
the early 1970's, increasing air-traffic volume and fuel costs sparked 
an interest in reducing vertical separation standards for aircraft 
operating above Flight Level (FL) 290. At the time, the FAA required 
aircraft operating above FL 290 to maintain a minimum of 2,000 feet of 
vertical separation between routes. Use of these high-altitude routes 
was desirable because the diminished atmospheric drag at high altitudes 
results in a corresponding increase in aircraft fuel efficiency. 
Operators sought, and continue to seek, not only the most direct 
routes, but also the most efficient altitudes for their aircraft. 
Increased demand for these high-altitude routes, however, has resulted 
in greater aircraft congestion in this airspace.
    In 1973, the Air Transport Association of America petitioned the 
FAA to reduce the vertical separation of high altitude routes from 
2,000 feet to 1,000 feet. The FAA denied the petition in 1977, in part 
because the technology to meet these more rigorous separation standards 
was neither generally available nor proven. Deficiencies included 
insufficient aircraft altitude-keeping standards, lack of maintenance 
and operational standards, and limited altitude correction technology.
    In mid-1981, the FAA initiated the Vertical Studies Program. This 
program, in conjunction with RTCA (formerly the Radio Technical 
Commission for Aeronautics) Special Committee (SC)-150 and the 
International Civil Aviation Organization (ICAO) Review of General 
Concept of Separation Panel, determined:
     RVSM is ``technically feasible without imposing 
unreasonably demanding technical requirements on the equipment.''
     RVSM could provide ``significant benefits in terms of 
economy and en-route airspace capacity.''
     Implementation of RVSM would require ``sound operational 
judgment supported by an assessment of system performance based on: 
aircraft altitude-keeping capability, operational considerations, 
system performance monitoring, and risk assessment.''
    Following these determinations, the FAA began a two-phase 
implementation process for RVSM operations for aircraft registered in 
the United States. During the first phase in 1997, the FAA added Sec.  
91.706 (Operations within airspace designed as RVSM Airspace) and 
Appendix G (Operations in RVSM Airspace) of part 91 (62 FR 17487; Apr. 
9, 1997). Section 91.706 permits operators of U.S.-registered aircraft 
to operate in RVSM airspace outside of the United States (U.S.) in 
accordance with the provisions of Appendix G. Appendix G contains a set 
of operational, design, maintenance, and other standards applicable to 
operators seeking to operate in RVSM airspace. It specifies a detailed 
application process that requires an operator to provide evidence that 
the operator's aircraft design satisfies RVSM performance requirements 
and the operator has policies and procedures for the safe conduct of 
RVSM operations. Until recently, it also required that the operator 
have a specific program for the maintenance of RVSM systems and 
equipment. The FAA reviews the applications and grants authorizations 
to operate in RVSM airspace after finding that the applicable 
requirements are met.
    The second phase of RVSM implementation occurred in October 2003, 
with a second RVSM-related rulemaking action (68 FR 61304; Oct. 27, 
2003). This rule introduced RVSM airspace in the U.S. and used the same 
authorization process previously established under Appendix G of part 
91. As established in 2003, the FAA's RVSM program allows for 1,000 
feet of vertical separation for aircraft between FL 290 and FL 410. 
Before the 2003 final rule, air traffic controllers could only assign 
aircraft operating under Instrument Flight Rules (IFR) flying at FL 290 
and above to FL 290, 310, 330, 350, 370, 390, and 410 since the 
existing vertical separation standard was 2,000 feet. After the rule 
changes went into effect, IFR aircraft could also fly at FL 300, 320, 
340, 360, 380, and 400--nearly doubling capacity within this particular 
segment of airspace.
    The FAA also implemented a performance-monitoring program to 
support implementation of RVSM. This program included Global 
Positioning System based height-keeping monitoring units capable of 
being deployed onboard aircraft during individual RVSM flights. Later, 
in 2005, the FAA deployed the first of five passive ground-based 
aircraft geometric height measurement element sites in the continental 
U.S. to conduct height-keeping performance monitoring of aircraft 
passing over each site. Other civil aviation authorities throughout the 
world have also developed similar height monitoring sites.
    In 2008, the FAA reviewed its RVSM program and operator 
authorization policies. At that time, there were more than 7,000 active 
RVSM authorizations, covering in excess of 15,000 U.S.-registered 
aircraft. The FAA's evaluation found the existing processes ensured 
compliance with the RVSM operating requirements. At the same time 
however, FAA representatives began meeting with the National Business 
Aviation Association (NBAA) to develop ways to streamline the RVSM 
application process to lower the burden on operators to obtain RVSM 
authorizations and reduce the FAA's workload associated with processing 
and granting these authorizations. The parties formed the RVSM Process 
Enhancement Team (PET) within the Performance Based Aviation Rulemaking 
Committee. The PET submitted its final recommendations to the FAA in 
2013. As a result, the FAA revised existing policies and guidance to 
facilitate more efficient processing of requests to change existing 
authorizations and created a job aid to assist inspectors in 
standardizing reviews of operator applications.
    The FAA also completed rulemaking in 2016 to further reduce the 
burden on applicants by eliminating the requirement that RVSM 
applicants include an approved RVSM maintenance program as part of an 
application for an RVSM authorization (81 FR 47009, July 20, 2016). 
RVSM technology has matured and most aircraft manufactured today that 
are capable of operating in RVSM airspace are delivered from the 
manufacturer as RVSM compliant. RVSM airspace has been implemented 
worldwide, familiarity with operational policy and procedures has 
significantly increased, and the vast majority of the RVSM capable 
fleet demonstrates excellent altimetry system performance. 
Additionally, the increasing equipage of aircraft with ADS-B Out 
systems makes the current process of obtaining RVSM authorizations for 
operation of these aircraft in RVSM airspace unnecessary, as ADS-B Out 
enables continual monitoring of aircraft height-keeping performance and 
rapid notification of altimetry system error (ASE).
    Currently operators are required to be issued a specific RVSM 
authorization by

[[Page 65489]]

the FAA's Flight Standards Service prior to operating in RVSM airspace. 
Until an operator's application is processed and the authorization 
issued, the operator cannot operate in RVSM designated airspace, Flight 
Levels (FL) 290-410 inclusive. During the application processing 
period, the aircraft may only be operated at FL 280 and below. Aircraft 
operations at lower altitudes are less efficient due to their higher 
fuel burn rates and lower true airspeeds.

A. Summary of the Notice of Proposed Rulemaking (NPRM)

    In August 2017, the FAA issued an NPRM (82 FR 36697; August 7, 
2017) that proposed to amend the FAA's application requirements to 
operate in RVSM airspace. In that NPRM, the FAA proposed to amend 
Appendix G of 14 CFR part 91 to:
     Add a new Section 9 (Aircraft Equipped with Automatic 
Dependent Surveillance-Broadcast Out) to authorize operators of 
aircraft, equipped with qualified ADS-B Out systems (i.e., systems that 
meet the requirements of Sec.  91.227) that can be monitored by the FAA 
to conduct RVSM operations without submitting an application for an 
authorization to operate in RVSM airspace.
     Revise Section 8 (Airspace Designation) acknowledging RVSM 
is now applied worldwide and remove the detailed RVSM airspace 
designations from that section.
    The FAA also proposed additional conforming amendments to Appendix 
G of part 91 facilitating the addition of the approval requirements 
specified in new Section 9 for ADS-B Out equipped aircraft. These 
proposed conforming amendments would:
     Revise Section 1 (Definitions) recognizing that RVSM is no 
longer a new concept and that RVSM operations have become standard 
between FL 290 and FL 410.
     Revise Section 2 (Aircraft Approval) and Section 3 
(Operator Authorization) to recognize aircraft operators may either use 
the current aircraft approval process specified in Section 2 and the 
operator authorization process specified in Section 3, or the 
authorization process in new Section 9 for aircraft equipped with 
qualified ADS-B Out systems to obtain authorization to conduct RVSM 
operations.
     Revise Section 3 (Operator Authorization) to permit an 
operator to be authorized to conduct flight in airspace where RVSM is 
applied under the provisions of this section, as is currently 
permitted, or under the provisions of new Section 9. The section would 
also be revised to better express the intent of the rule by stating 
that ``each pilot has knowledge of RVSM requirements, policies, and 
procedures sufficient to conduct operations in RVSM airspace.''
     Revise Section 4 (RVSM Operations) to require that pilots 
of aircraft of operators who have been authorized to conduct RVSM 
operations in accordance with proposed Section 9 have knowledge of the 
requirements, policies, and procedures sufficient for the conduct 
operations in RVSM airspace.
     Revise Section 5 (Deviation Authority Approval) to 
eliminate the specific references to Section 3 since the Administrator 
may authorize deviations from the requirements in Sec. Sec.  91.180 and 
91.706 for a specific flight in RVSM airspace for operators who may not 
meet the provisions of current Section 3 or proposed Section 9.
     Revise Section 7 (Removal or Amendment of Authority) to 
eliminate specific references to the revocation or restriction of RVSM 
authorizations and letters of authorization and replace those 
provisions with a more general provision stating that the Administrator 
may prohibit or restrict operation in RVSM airspace if an operator 
fails to comply with certain specified provisions.

B. General Overview of Comments

    The comment period for the NPRM closed on September 6, 2017. The 
FAA received 16 comments, mostly from individual aircraft operators. 
Other commenters included the National Business Aviation Association 
(NBAA), the Aircraft Owners and Pilots Association (AOPA), and the 
General Aviation Manufacturers Association (GAMA). All 16 comments 
supported the rule change with 10 of the individual commenters 
supporting the rule's benefits of reducing the burden to operators. 
Based on the comments received, the FAA adopts the amendments as 
proposed with only minor non-substantive editorial changes to 
facilitate publication in the Code of Federal Regulations.

III. Discussion of Public Comments and Final Rule

Comments Regarding the Proposal

    All the commenters supported the proposal. The majority of the 
commenters, including NBAA, AOPA, and GAMA, stated that the reduction 
in regulatory requirements for operator authorization would be cost 
beneficial for operators by:
     Reducing the burden and expense of having to make 
application for authorization to operate in RVSM airspace; and
     Allowing operations at RVSM fuel-efficient altitudes 
sooner without degrading safety.
    NBAA commented the new rule is a logical extension of the work the 
FAA has been doing to further streamline the [RVSM authorization] 
process while maintaining the highest levels of safety. The FAA notes 
that this final rule eliminates the requirement to make application for 
RVSM authorization if an operator chooses to leverage the technology 
gains obtained in ADS-B Out equipage, in accordance with Sec. Sec.  
91.180 and 91.706, while continuing to require that operators meet the 
equipment and performance standards specified in Appendix G of part 91. 
The rule provides operators with an additional means to obtain 
authorization to operate in RVSM airspace but does not change the 
height keeping requirements for operations in that airspace. The use of 
ADS-B Out allows the FAA to continually and more accurately monitor an 
aircraft's height keeping performance in RVSM airspace thereby 
providing the agency with the ability to more rapidly mitigate the 
risks posed by poor performing aircraft. The FAA believes that these 
changes not only reduce operator and FAA workload and expense, but also 
accomplish these objectives with no additional risk or impact on the 
level of safety provided by the FAA's current RVSM authorization 
process.
    AOPA commented that the proposed modifications to part 91 will 
result in significant cost and time savings for general aviation and 
the FAA, while ensuring no degradation to safety. The FAA has 
determined the current fleet of RVSM approved aircraft consistently 
meets FAA established safety standards for operations in RVSM airspace. 
The FAA notes that aircraft equipped with qualified ADS-B Out systems 
may conduct operations in airspace where the FAA has ADS-B coverage 
sufficient to confirm RVSM height-keeping performance, under the 
provisions of new Section 9 of Appendix G, immediately upon the 
effective date of this rule. However, an operator may still operate 
with an authorization issued under the provisions of Section 3 of 
Appendix G if its aircraft is not equipped with a qualified ADS-B Out 
system. The FAA also notes that if a foreign country requires a 
specific authorization to operate in RVSM airspace, as specified in 
ICAO Annex 6, an operator may need to seek authorization under the 
provisions of Section 3, even if it meets the provisions of Section 9.

[[Page 65490]]

    GAMA supported the proposed changes and commented that the rule 
further builds on prior discussions between the FAA and industry to 
streamline and reduce the burden of the operational authorization 
process for general aviation operators. GAMA stated that it helps 
provide additional NextGen-driven benefits to the industry.
    NBAA commented that operating in RVSM airspace has become very 
common and an integral part of operating aircraft in their most 
efficient state. The FAA agrees that adopting the proposed rule changes 
will increase safety in RVSM airspace where ADS-B monitoring is 
available and reduce delays in receiving approval for operations in 
RVSM airspace.
    There were 10 additional individual commenters who expressed strong 
support for this action with similar statements recognizing the 
``cumbersome and costly'' RVSM authorization process and that the core 
benefits of compressing high-level airspace have been offset by long 
delays in the FAA review and authorization process.
    The FAA agrees with the commenters that the general aviation 
community will obtain significant benefits from this action, including 
that the rule takes an important step in removing an approval process 
that is no longer justifiable as pilots equip with advanced NextGen 
technology.

Other Comments

    One commenter stated that the proposal was ``a good start'' but did 
not go far enough and there should be no RVSM authorization at all. In 
the NPRM, the FAA only proposed to remove the requirement to submit an 
application for RVSM authorization if an aircraft is equipped with a 
qualified ADS-B Out system. The FAA did not propose to eliminate the 
authorization requirement in Sec. Sec.  91.180 or 91.706 and considers 
the commenter's recommendation outside the scope of this rulemaking. 
The FAA notes that ICAO Annex 6 continues to require that an airplane 
used to conduct operations in RVSM airspace be specifically authorized 
to conduct those operations by the State of the operator or State of 
registry, as applicable. The annex further specifies that prior to 
issuing the authorization, the issuing State must be satisfied that the 
vertical performance of the airplane meets applicable height-keeping 
requirements and that the operator has instituted appropriate 
flightcrew operating procedures and procedures for continued 
airworthiness of the airplane.
    One commenter was concerned about eliminating the authorization due 
to the potential for transponder failure and felt that the FAA should 
conduct further review of ADS-B and transponder failure issues. The FAA 
notes that the ADS-B Out equipment requirement in Section 9(a)(5) is 
necessary for aircraft height-keeping performance monitoring and that 
failure of an aircraft's transponder does not hinder the ability of the 
aircraft to maintain the requisite aircraft height-keeping capability 
in RVSM airspace. Transponder failure procedures in RVSM airspace are 
addressed in FAA and ICAO guidance material.
    One commenter stated the use of ADS-B technology will deconflict 
aircraft within RVSM airspace without the need for expensive altimetry 
instruments. The FAA notes that for an aircraft to be eligible for 
operations in RVSM airspace it must meet strict height-keeping 
performance standards. ADS-B Out provides information used to determine 
an aircraft's ASE. ADS-B alone does not provide operators with the 
requisite height-keeping capability to conduct operations in RVSM 
airspace safely. Accordingly, the installation of a qualified ADS-B Out 
system in an aircraft that does not have the altitude-keeping 
capability necessary to meet RVSM performance requirements would not 
permit that aircraft to operate in RVSM airspace.

Recent Regulatory Actions

    As discussed in the ``Background'' section of this document, RVSM 
was implemented regionally in a phased approach. Section 8 (Airspace 
Designation) of Appendix G was initially designed to be updated 
whenever regions added RVSM airspace. The inability to update these 
designations rapidly caused discrepancies between the airspace listed 
in Section 8 of Appendix G and the airspace in which RVSM had been 
applied. Today, however, RVSM has been established between FL 290 and 
FL 410 in all flight information regions and requirements have been 
harmonized throughout ICAO member States.
    The FAA recently amended the airspace designations in Section 8 of 
Appendix G by only revising the name of the North Atlantic airspace (82 
FR 39660; Aug. 22, 2017). Since the action in this rule was pending at 
the time, it would have been inconsistent for the FAA to make all the 
other changes in that rule while leaving out the change to Section 8 of 
Appendix G in anticipation of the changes made by this rule. 
Accordingly, there is no longer a need to update the airspace 
designations listed in Section 8. The amendment to this section 
acknowledges RVSM is now applied worldwide and removes the detailed 
RVSM airspace designations from that section, as proposed.

C. Changes From the NPRM

    The FAA has made no changes to the proposal as set forth in the 
NPRM other than minor non-substantive editorial changes to facilitate 
publication in the Code of Federal Regulations.

IV. Regulatory Notices and Analyses

A. Regulatory Evaluation

    Changes to Federal regulations must undergo several economic 
analyses. First, Executive Order 12866 and Executive Order 13563 direct 
that each Federal agency shall propose or adopt a regulation only upon 
a reasoned determination that the benefits of the intended regulation 
justify its costs. Second, the Regulatory Flexibility Act of 1980 (Pub. 
L. 96-354) requires agencies to analyze the economic impact of 
regulatory changes on small entities. Third, the Trade Agreements Act 
(Pub. L. 96-39) prohibits agencies from setting standards that create 
unnecessary obstacles to the foreign commerce of the United States. In 
developing U.S. standards, this Trade Act requires agencies to consider 
international standards and, where appropriate, that they be the basis 
of U.S. standards. Fourth, the Unfunded Mandates Reform Act of 1995 
(Pub. L. 104-4) requires agencies to prepare a written assessment of 
the costs, benefits, and other effects of proposed or final rules that 
include a Federal mandate likely to result in the expenditure by State, 
Local, or Tribal governments, in the aggregate, or by the private 
sector, of $100 million or more annually (adjusted for inflation with 
base year of 1995; current value is $155 million). This portion of the 
preamble summarizes the FAA's analysis of the economic impacts of this 
final rule. We suggest readers seeking greater detail read the full 
regulatory evaluation, a copy of which we have placed in the docket for 
this rulemaking.
    In conducting these analyses, the FAA has determined that this 
final rule: (1) Has benefits that justify its costs, (2) is not an 
economically ``significant regulatory action'' as defined in Section 
3(f) of Executive Order 12866, (3) is ``nonsignificant'' as defined in 
DOT's Regulatory Policies and Procedures; (4) will not have a 
significant economic impact on small entities; (5) will not create 
unnecessary obstacles to the foreign commerce of the United States; and 
(6) will not impose an unfunded

[[Page 65491]]

mandate on State, Local, or Tribal governments, or on the private 
sector by exceeding the threshold identified above. These analyses are 
summarized below.
i. Who is potentially affected by this rule?
    All operators intending to conduct operations between FL 290 and FL 
410 (RVSM designated Airspace) and have 1,000 feet vertical separation 
applied. This applies to operations conducted under parts 91, 121, 125, 
and 135.
ii. Assumptions
     Present value estimates based on OMB guidance using a 7 
percent discount rate.
     The benefits begin to accrue in 2019.
     The analysis period is 5 years from 2019 to 2023.
iii. Benefits and Cost Savings of This Rule
    The final rule will permit an operator of an aircraft meeting 
equipment requirements for operations in RVSM airspace and equipped 
with a qualified ADS-B Out system to operate in RVSM airspace without 
requiring application for a specific authorization. This rulemaking 
will eliminate this application requirement, thereby reducing both 
operators' costs and FAA workload, while maintaining the existing level 
of safety. The biggest savings comes not from the paperwork savings but 
from fuel savings. Currently, operators without RVSM approval must 
operate their airplanes at lower altitudes.
    Total savings during the first 5 years of the rule's implementation 
will be approximately $34.0 million or $27.5 million present value at 7 
percent, with annualized savings of $6.7 million.

B. Final Regulatory Flexibility Determination

    The Regulatory Flexibility Act of 1980 (Pub. L. 96-354) (RFA) 
establishes ``as a principle of regulatory issuance that agencies shall 
endeavor, consistent with the objectives of the rule and of applicable 
statutes, to fit regulatory and informational requirements to the scale 
of the businesses, organizations, and governmental jurisdictions 
subject to regulation.'' To achieve this principle, agencies are 
required to solicit and consider flexible regulatory proposals and to 
explain the rationale for their actions to assure that such proposals 
are given serious consideration. The RFA covers a wide-range of small 
entities, including small businesses, not-for-profit organizations, and 
small governmental jurisdictions.
    Agencies must perform a review to determine whether a rule has a 
significant economic impact on a substantial number of small entities. 
If the agency determines that it does, the agency must prepare a 
regulatory flexibility analysis as described in the RFA.
    However, if an agency determines that a rule is not expected to 
have a significant economic impact on a substantial number of small 
entities, Section 605(b) of the RFA provides that the head of the 
agency may so certify and a regulatory flexibility analysis is not 
required. The certification must include a statement providing the 
factual basis for this determination, and the reasoning should be 
clear. The FAA estimates that this rulemaking saves each affected small 
entity operating aircraft equipped with qualified ADS-B Out systems 
under part 91 and part 135 $1,630 from not having to apply for an RVSM 
authorization and from reduced fuel cost associated with not being 
restricted from RVSM operations while the authorization is processed. 
The total relief of $1,630 for each part 91 and part 135 operator 
seeking authorization for aircraft equipped with ADS-B Out is the sum 
of the estimated $214 per application preparation relief, plus the per 
aircraft fuel savings estimate of $1,416. The FAA then compared this 
cost saving with a weighted average aircraft value of representative 
aircraft potentially be affected by this rule (See following table).
[GRAPHIC] [TIFF OMITTED] TR21DE18.019

    Owners of new turbojet or turboprop airplanes receive a benefit of 
$1,630 per new airplane. For new turbojet or turboprop airplanes whose 
value exceeds $3 million, the cost savings of less than $2,000 is not 
economically significant.
    If an agency determines that a rulemaking will not result in a 
significant economic impact on a substantial number of small entities, 
the head of the agency may so certify under Section 605(b) of the RFA. 
Therefore, as provided in Section 605(b), the head of the FAA certifies 
that this rulemaking will not result in a significant economic impact 
on a substantial number of small entities.

C. International Trade Impact Assessment

    The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the 
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal 
agencies from establishing standards or engaging in related activities 
that create unnecessary obstacles to the foreign commerce of the United 
States. Pursuant to these Acts, the establishment of standards is not 
considered an unnecessary obstacle to the foreign commerce of the 
United States, so long as the standard has a legitimate domestic 
objective, such as the protection of safety, and does not operate in a 
manner that excludes imports that meet this objective. The statute also 
requires consideration of international standards, and where 
appropriate, that they be the basis for U.S. standards. The FAA has 
assessed the potential effect of this rule and determined that it has 
the same impact on domestic and international entities and thus has a 
neutral trade impact.

D. Unfunded Mandates Assessment

    Title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-
4)

[[Page 65492]]

requires each Federal agency to prepare a written statement assessing 
the effects of any Federal mandate in a proposed or final agency rule 
that may result in an expenditure of $100 million or more (in 1995 
dollars) in any 1 year by State, Local, and Tribal governments, in the 
aggregate, or by the private sector; such a mandate is deemed to be a 
``significant regulatory action.'' The FAA currently uses an inflation-
adjusted value of $155 million in lieu of $100 million. This rule does 
not contain such a mandate; therefore, the requirements of Title II of 
the Act do not apply.

E. Paperwork Reduction Act

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires 
that the FAA consider the impact of paperwork and other information 
collection burdens imposed on the public. According to the 1995 
amendments to the Paperwork Reduction Act (5 CFR 1320.8(b)(2)(vi)), an 
agency may not collect or sponsor the collection of information, nor 
may it impose an information collection requirement unless it displays 
a currently valid Office of Management and Budget (OMB) control number.
    As described in the regulatory evaluation, this rule will relieve 
the existing RVSM information collection burden for certain operators. 
Under currently approved information requirements (OMB 2120-0679), 
operators seeking approval to conduct RVSM operations must submit 
application to the FAA for authorization. This rule change will 
eliminate the application requirement for operators choosing to equip 
their aircraft with qualified ADS-B Out systems. As required by the 
Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)), the FAA will 
submit information collection amendments to OMB for its review after 
publication of this final rule. Notice of OMB approval of this revised 
information collection will be published in the Federal Register.

F. International Compatibility and Cooperation

    In keeping with U.S. obligations under the Convention on 
International Civil Aviation, it is FAA policy to conform to 
International Civil Aviation Organization (ICAO) Standards and 
Recommended Practices to the maximum extent practicable. The FAA has 
reviewed the corresponding ICAO Standards and Recommended Practices and 
has identified no differences with these regulations.

V. Executive Order Determinations

A. Executive Order 13771, Reducing Regulation and Controlling 
Regulatory Costs

    This rule is an Executive Order 13771 titled ``Reducing Regulation 
and Controlling Regulatory Costs,'' deregulatory action. Details on the 
estimated costs savings of this rule can be found in the rule's 
economic analysis.

B. Executive Order 13132, Federalism

    The FAA has analyzed this rule under the principles and criteria of 
Executive Order 13132, Federalism. The agency has determined that this 
action will not have a substantial direct effect on the States, or the 
relationship between the Federal Government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government, and, therefore, will not have Federalism implications.

C. Executive Order 13211, Regulations That Significantly Affect Energy 
Supply, Distribution, or Use

    The FAA analyzed this rule under Executive Order 13211, Actions 
Concerning Regulations that Significantly Affect Energy Supply, 
Distribution, or Use (May 18, 2001). The agency has determined that it 
will not be a ``significant energy action'' under the executive order 
and will not be likely to have a significant adverse effect on the 
supply, distribution, or use of energy.
