    investigating UAS incidents.
    7 Additionally, part 107 allows individuals to request waivers from
    certain provisions, including those prohibiting operations at night
    and over people. This proposed
    rule, in concert with the FAA’s proposed rule for operations over
    people would create cost

    7 This analysis includes quantified savings to the FAA only. A variety
    of other entities involved with airport
    operations, facility and infrastructure security, and law enforcement
    would also save time and resources involved
    with UAS identification and incident reporting, response and
    investigation. The FAA plans to update its estimates of
    savings for additional information and data identified during the
    comment period and development of the final rule.

    savings for the FAA and part 107 operators by avoiding the time
    expended processing waivers
    for these activities.8
    The analysis of this proposed rule is based on the fleet forecast for
    small unmanned
    aircraft as published in the FAA Aerospace Forecast.9
    The forecast includes base, low, and high
    scenarios. This analysis provides a range of net impacts from low to
    high based on these forecast
    scenarios. The FAA considers the primary estimate of net impacts of
    the proposed rule to be the
    base scenario. For the primary estimate, over a 10-year period of
    analysis this proposed rule
    would result in net present value costs of about $582 million at a
    three percent discount rate with
    annualized net costs of about $68 million. At a seven percent discount
    rate, the net present value
    costs are about $474 million with annualized net costs of $67 million.
    The following table
    presents a summary of the primary estimates of the quantified costs
    and cost savings of this
    proposed rule. Additional details, including low and high estimates of quantified net costs, are
    provided in the Regulatory Evaluation section of this proposal and in
    the Preliminary Regulatory
    Impact Analysis available in the docket for this rulemaking.

    8 On February 13, 2019, the FAA published a notice of proposed
    rulemaking titled “Operation of Small Unmanned
    Aircraft Systems over People,” (84 FR 3856) in which the FAA proposed
    to allow operations of small unmanned
    aircraft over people in certain conditions and operations of small UAS
    at night without obtaining a waiver.

    The FAA expects this proposed rule will result in several important
    benefits and
    enhancements to support the safe integration of expanded UAS
    operations in the airspace of the
    United States. The proposal would provide situational awareness of UAS operations to other
    aircraft and airport operators. The proposed rule would provide
    information to distinguish
    compliant UAS users from those potentially posing a safety or security
    risk. The following table
    summarizes the benefits of the proposed rule.
    Table 3: Summary of Benefits of Proposed Rule
    Safety and Security ? Provides situational awareness of UAS flying in
    the airspace of
    the United States to other aircraft in the vicinity of those
    operations and airport operators.
    ? Provides information to distinguish compliant UAS users from
    those potentially posing a safety or security risk.
    ? Enables the FAA, national security agencies, and law
    enforcement entities to obtain situational awareness of UAS in
    the airspace of the United States in near real-time.
    ? Provides additional registration and notification requirements
    for identifying aircraft and promoting accountability and the
    safe and efficient use of the airspace of the United States.
    Enables Expanded
    Operations and
    UAS Integration
    ? Assists in the implementation of operations of small UAS over
    people and at night. A final rule for operation of small UAS
    over people and at night is contingent upon a final action for
    UAS with remote identification being in effect.
    34
    ? Provides UAS-specific data to facilitate future, more advanced
    operational capabilities, such as detect-and-avoid and
    aircraftto-aircraft communications that support beyond visual line of
    sight (BVLOS) operations.
    ? Provides UAS-specific data to develop a comprehensive UAS
    traffic management (UTM) system that would facilitate the
    safe expansion of operations.
    In addition, the proposed rule provides flexibility through minimum
    performance
    requirements that would accommodate future innovation and improve the efficiency of UAS
    operations. The proposal also does not preclude early compliance for
    UAS producers or
    operators to realize earlier expanded operations and commercial
    opportunities.
    E. Structure of this Proposed Rule
    This proposed rule addresses remote identification of UAS from a
    number of
    perspectives: UAS owners, UAS operators, UAS designers and producers, developers of remote
    identification means of compliance, and Remote ID USS. The FAA
    recognizes that certain
    persons may only be interested in certain topics. Therefore, the
    following provides the structure
    of this proposed rule.
    Section II of this preamble discusses the FAA’s legal authority for promulgating this
    proposed rule.
    Section III of this preamble discusses the integration of UAS into the
    airspace of the
    United States. The complexities surrounding the full integration of
    UAS into the airspace of the
    United States has led the FAA to engage in a phased, incremental, and risk-based approach to
    rulemaking based on the statutory authorities delegated to the agency.
    35
    Section IV of this preamble discusses the need for remote
    identification of UAS
    operating in the airspace of the United States. The section addresses
    the role of the FAA as the
    United States civil aviation authority and air navigation service
    provider, current registration
    requirements and how those requirements do not provide information
    responsive to remote
    identification, current cooperative surveillance for manned aircraft,
    and the need for situational
    awareness. The section further explains how remote identification of
    UAS fits within the FAA’s
    compliance and enforcement programs. The section describes how the FAA envisions remote
    identification may facilitate beyond visual line of sight (BVLOS)
    operations in the future. The
    potential benefits of remote identification of UAS to national
    security and law enforcement
    agencies are noted.
    Section V of this preamble discusses related international activities.
    Section VI of this preamble provides a summary of the Unmanned
    Aircraft Systems
    (UAS) Identification (ID) and Tracking Aviation Rulemaking Committee
    (ARC) (UAS-ID ARC)
    report and the FAA’s response to that report.
    Section VII of this preamble discusses the new terms to be defined as
    part of this
    proposed rule.
    Section VIII of this preamble describes the applicability of the
    proposed rule. It also
    discusses the framework of the following sections: operating
    requirements for UAS with remote
    identification, means of compliance, and design and production
    requirements.
    Section IX of this preamble discusses the current registration
    requirements for unmanned
    aircraft under part 47 and part 48 and the issues with the current
    registration requirements in light
    of the need for remote identification of UAS. The section also
    discusses the FAA’s proposed
    36
    revision of the registration requirements of part 48 to require the
    individual registration of
    unmanned aircraft and the proposed use of unmanned aircraft serial
    numbers as unique
    identifiers for remote identification purposes.
    Section X of this preamble explains the operating requirements related
    to remote
    identification of UAS. It describes the requirements for standard
    remote identification UAS and
    limited remote identification UAS. It also discusses the proposed
    requirements for UAS without
    remote identification. The section provides the proposed requirements
    to transmit and broadcast,
    as appropriate, message elements. It discusses the FAA’s proposal to
    prohibit the use of ADS-B
    Out to satisfy remote identification of UAS. Finally, it discusses UAS operators’ requirement to
    operate a UAS with remote identification only if that UAS is listed on
    a valid FAA-accepted
    declaration of compliance.
    Section XI of this preamble discusses law enforcement access to remote identification
    information.
    Section XII of this preamble discusses the FAA’s proposed requirements
    for what an
    FAA-accepted means of compliance for remote identification would
    contain. The FAA is
    proposing that any FAA-accepted means of compliance contain
    requirements regarding the
    message elements to be transmitted and the minimum performance
    requirements for the
    transmission and broadcast, as appropriate, of those elements. The
    section discusses the process
    to submit and have the FAA accept a means of compliance, and data
    retention requirements for
    submitters of means of compliance. The section also discusses other requirements the FAA
    considered in the development of this proposed rule.
    Section XIII of this preamble provides the proposed design and
    production requirements.
    It discusses the proposed requirement that producers of standard
    remote identification UAS and
    37
    limited remote identification UAS issue serial numbers for UAS and
    that persons producing
    UAS with remote identification would be required to do so in
    accordance with the minimum
    performance requirements of the proposed rule using an FAA-accepted
    means of compliance.
    The section also describes the requirement for producers to submit a declaration of compliance,
    followed by a description of the process for FAA acceptance of
    declarations of compliance,
    rescission of those declarations, and the right of a person who
    submitted the FAA-accepted
    declaration of compliance or any person adversely affected by the
    rescission of the
    Administrator’s acceptance of a declaration of compliance to petition
    for reconsideration of a
    rescission. Finally, the section discusses data retention requirements
    for producers submitting
    FAA-accepted declarations of compliance.
    Section XIV of this preamble discusses the role of Remote ID USS. The
    section describes
    the FAA’s vision regarding the role of Remote ID USS in providing
    remote identification
    services as well as how they will be established and what data
    provided to them will be publicly
    available. The section also describes the FAA’s vision for data
    privacy and information security.
    Section XV of this preamble provides the overarching requirements for FAA-recognized
    identification areas to be used by UAS that cannot, or do not, comply
    with the proposed remote
    identification requirements.
    Section XVI of this preamble discusses the circumstances under which
    the use of ADS-B
    Out and transponders for UAS would be prohibited.
    Section XVII of this preamble provides the proposed effective dates
    and compliance
    dates.
    Section XVIII of this preamble discusses the proposed guidance
    documents.
    38
    Sections XIX and XX of this preamble address the FAA’s requirements to
    comply with
    various statutes and Executive Orders pertaining to all regulations.
    Section XXI of this preamble discusses the tribal considerations
    related to this proposed
    rule.
    Section XXII of this preamble discusses the privacy impact analysis
    the FAA conducted
    as part of this proposed rule.
    Section XXIII of this preamble provides additional information to
    persons wishing to
    provide comments to this proposed rule.
    II. Authority for this Rulemaking
    The FAA’s authority to issue rules on aviation safety is found in
    Title 49 of the United
    States Code (49 U.S.C.). Subtitle I, section 106 describes the
    authority of the FAA
    Administrator. Subtitle VII, Aviation Programs, describes in more
    detail the scope of the
    Agency’s authority.
    This rulemaking is promulgated pursuant to 49 U.S.C. 40103(b)(1) and
    (2), which direct
    the FAA to issue regulations: (1) to ensure the safety of aircraft and
    the efficient use of airspace;
    and (2) to govern the flight of aircraft for purposes of navigating,
    protecting and identifying
    aircraft, and protecting individuals and property on the ground. In
    addition,
    49 U.S.C. 44701(a)(5) charges the FAA with promoting safe flight of
    civil aircraft by prescribing
    regulations the FAA finds necessary for safety in air commerce and
    national security.
    Section 2202 of Pub. L. 114-190 requires the Administrator to convene
    industry
    stakeholders to facilitate the development of consensus standards for
    remotely identifying
    39
    operators and owners of UAS and associated unmanned aircraft and to
    issue regulations or
    guidance based on any standards developed.
    The Administrator is granted the authority under 49 U.S.C. 44805 to
    establish a process
    for, among other things, accepting risk-based consensus safety
    standards related to the design
    and production of small UAS. Under 49 U.S.C. 44805(b)(7), one of the considerations the
    Administrator must take into account prior to accepting such standards
    is any consensus
    identification standard regarding remote identification of unmanned
    aircraft developed pursuant
    to section 2202 of Pub. L. 114-190.
    Additionally, section 44809(f) of 49 U.S.C. provides that the
    Administrator is not
    prohibited from promulgating rules generally applicable to unmanned
    aircraft, including those
    unmanned aircraft eligible for the exception for limited recreational operations of unmanned
    aircraft. Among other things, this authority extends to rules relating
    to the registration and
    marking of unmanned aircraft and the standards for remotely
    identifying owners and operators of
    UAS and associated unmanned aircraft.
    The FAA has authority to regulate registration of aircraft under 49
    U.S.C. 44101–44106
    and 44110–44113, which require aircraft to be registered as a
    condition of operation and
    establish the requirements for registration and registration
    processes.
    Finally, this rulemaking is promulgated under the authority described
    in 49 U.S.C. 106(f),
    which establishes the authority of the Administrator to promulgate
    regulations and rules, and
    49 U.S.C. 40101(d), which authorizes the FAA to consider in the public interest, among other
    things, the enhancement of safety and security as the highest
    priorities in air commerce, the
    regulation of civil and military operations in the interest of safety
    and efficiency, and assistance
    40
    to law enforcement agencies in the enforcement of laws related to
    regulation of controlled
    substances, to the extent consistent with aviation safety.
    III. Integration of UAS into the Airspace of the United States
    The rapid proliferation of UAS has created significant opportunities
    and challenges for
    their integration into the airspace of the United States. The
    relatively low cost of highly capable
    UAS technology has allowed for hundreds of thousands of new operators
    to enter the aviation
    community.
    The complexities surrounding the full integration of UAS into the
    airspace of the United
    States have led the FAA to engage in a phased, incremental, and
    risk-based approach to
    rulemaking based on the statutory authorities delegated to the agency.
    On December 16, 2015,
    the FAA and DOT jointly published an interim final rule in the Federal
    Register titled
    Registration and Marking Requirements for Small Unmanned Aircraft (“Registration Rule”),10
    which provided for a web-based aircraft registration process for small
    unmanned aircraft in
    14 CFR part 48, to serve as an alternative to the registration
    requirements for aircraft established
    in 14 CFR part 47. The Registration Rule imposed marking requirements
    on small unmanned
    aircraft registered under part 48 to display a unique identifier in a
    manner that is visible upon
    inspection. This unique identifier could be the registration number
    issued to an individual or to
    the aircraft by the FAA Registry or the small unmanned aircraft’s
    serial number if authorized by
    the Administrator and provided with the application for the
    certificate of aircraft registration.

    10 80 FR 78594.
    41
    On June 28, 2016, the FAA and DOT jointly published the final rule for Operation and
    Certification of Small Unmanned Aircraft Systems (“The 2016 Rule”) in
    the Federal Register.
    11
    This was an important step towards the integration of civil small UAS operations (for aircraft
    weighing less than 55 pounds) into the airspace of the United States.
    The 2016 Rule set the initial
    operational structure and certain restrictions to allow routine civil operations of small UAS in the
    airspace of the United States in a safe manner. Prior to the 2016
    Rule, the FAA authorized
    commercial UAS operations, including real estate photography,
    precision agriculture, and
    infrastructure inspection, under section 333 of Pub. L. 112-95. Over
    5,500 operators received this
    authorization. The FAA also issued over 900 Certificates of Waiver or Authorization (COA),
    allowing Federal, State, and local governments, law enforcement
    agencies, and public
    universities to perform numerous tasks with UAS, including
    search-and-rescue, border patrol,
    and research. The 2016 Rule allows for certain operations of small UAS
    in the airspace of the
    United States without the need for airworthiness certification,
    exemptions, or certificates of
    waiver or authorization.
    The 2016 Rule also imposed certain restrictions on small UAS
    operations. The
    restrictions include a prohibition on nighttime operations,
    limitations on operations conducted
    during civil twilight, restrictions on operations over people, a
    requirement for all operations to be
    conducted within visual line of sight, and other operational,
    airspace, and pilot certification
    requirements. Since the rule took effect on August 29, 2016, most
    low-risk small UAS
    operations that were previously authorized on a case-by-case basis
    under Pub. L. 112-95
    section 333 are now considered routine operations. These operations
    are now permitted within

    11 81 FR 42064.
    42
    the requirements of part 107 without further interaction with the FAA. Publishing Part 107 was
    the first significant regulatory step to enable lower risk, less
    complex UAS operations.
    Part 107 opened the airspace of the United States to the vast majority
    of routine small
    UAS operations, allowing flight within visual line of sight while
    maintaining flexibility to
    accommodate future technological innovations. Part 107 allows
    individuals to request waivers
    from certain provisions, including those prohibiting operations over
    people and beyond visual
    line of sight. Petitions for waivers from the provisions of part 107
    must demonstrate that the
    petitioner has provided sufficient mitigations to safely conduct the
    requested operation.
    On October 5, 2018, Congress enacted Pub. L. 115-254, also known as
    the FAA
    Reauthorization Act of 2018. The FAA Reauthorization Act of 2018
    amended Part A of
    subtitle VII of title 49, United States Code by inserting a new
    chapter 448 titled Unmanned
    Aircraft Systems and incorporating additional authorities and mandates
    to support the further
    integration of UAS into the airspace of the United States, including
    several provisions that
    specifically deal with the need for remote identification of UAS.
    Section 376 of the FAA
    Reauthorization Act of 2018 requires the FAA to perform testing of
    remote identification
    technology and to assess the use of remote identification for the
    development of UTM.
    Additionally, congressional action supports the implementation of
    remote identification
    requirements for most UAS. Section 349 of the FAA Reauthorization Act
    of 2018 included a
    provision indicating that the Administrator is not prohibited from
    promulgating rules relating to
    the standards for remotely identifying owners and operators of UAS and associated unmanned
    43
    aircraft.
    12 The provision denotes Congress’s acknowledgment that remote
    identification is an
    essential part of the UAS regulatory framework. Section 349 also does
    not prohibit the
    Administrator from promulgating rules generally applicable to unmanned
    aircraft related to
    updates to the operational parameters for unmanned aircraft used for
    limited recreational
    operations, the registration and marking of unmanned aircraft, and
    other standards consistent
    with maintaining the safety and security of the airspace of the United
    States.
    13
    Lastly, on February 13, 2019, the FAA published three rulemaking
    documents in the
    Federal Register as part of the next phase for integrating small UAS
    into the airspace of the
    United States. The first of such documents was an interim final rule
    titled “External Marking
    Requirement for Small Unmanned Aircraft,”14 in which the FAA required
    small unmanned
    aircraft owners to display the registration number assigned by the FAA
    on an external surface of
    the aircraft. The second rulemaking document was a notice of proposed rulemaking titled
    “Operation of Small Unmanned Aircraft Systems Over People,”15 in which
    the FAA proposed to
    allow operations of small unmanned aircraft over people in certain
    conditions and operations of
    small UAS at night without obtaining a waiver. The third rulemaking
    document was an advance
    notice of proposed rulemaking titled “Safe and Secure Operations of
    Small Unmanned Aircraft
    Systems,”16 in which the FAA sought information from the public on
    whether and under which
    circumstances the FAA should promulgate new rules to require stand-off distances, additional
    operating and performance restrictions, the use of UAS Traffic
    Management (UTM), additional

    44
    payload restrictions, and whether the agency should prescribe design requirements and require
    that unmanned aircraft be equipped with critical safety systems.
    IV. Need for Remote Identification of UAS Operating in the Airspace of
    the United States
    A. Maintaining the Safety and Efficiency of the Airspace of the United
    States
    The FAA is both the civil aviation authority and the air navigation
    service provider
    (ANSP) for the United States. The FAA has statutory responsibilities
    to set standards and certify
    aircraft, airmen, and facilities. In addition, the FAA is responsible
    for ensuring the safe and
    efficient use of navigable airspace. The FAA carries out its
    responsibilities by developing air
    traffic rules, assigning the use of airspace, and controlling air
    traffic through a complex network
    of airport towers, air route traffic control centers, and flight
    service stations.
    The FAA is responsible for serving tens of thousands of commercial and
    private aircraft
    operating in 29 million square miles of airspace each day. Through its
    air traffic management
    (ATM) system, the FAA coordinates the movements of these aircraft to
    ensure they operate at
    safe distances from each other and manages disruptions to normal air
    traffic flow. The FAA’s
    ability to manage air traffic in the airspace of the United States is predicated on the agency
    knowing who is operating in the airspace and, if necessary, on being
    able to communicate with
    those airspace users.
    1. Existing Cooperative Surveillance System
    The ATM system relies on appropriately equipped aircraft to provide
    the surveillance
    services necessary to ensure the safety and efficiency of the airspace
    of the United States. In
    addition to ground-based equipment such as primary and secondary
    radar, participating aircraft
    45
    use ATC transponders and ADS-B Out to participate in the ATM’s
    cooperative surveillance
    environment. Transponders emit a radio frequency response when they
    are interrogated by
    ground-based secondary radar systems. Part of the response is the Mode
    3/A code which is a four
    digit number ranging from 0000 to 7777 that allows ATC to identify
    aircraft under radar
    surveillance and correlate the target to a flight plan. Other
    information provides ATC with the
    location of the aircraft, which is shown on ATC radar displays. After
    January 1, 2020, aircraft
    will be required to equip with ADS-B Out to operate in certain
    airspace.
    Some UAS, such as those operating in Class A airspace, are already
    equipped with
    transponders and ADS-B Out and operate in accordance with existing
    rules. But for the
    majority of UAS, especially those operating at low altitudes, the
    existing cooperative
    surveillance system is not capable of providing the necessary
    services.
    Currently, there is no regulatory requirement mandating the remote identification of
    unmanned aircraft other than the existing equipment rules in part 91
    for transponders that are
    applicable to aircraft in certain airspace and ADS-B Out, which will
    be required for aircraft in
    certain airspace after January 1, 2020. Because the majority of UAS
    operations occur at low
    altitudes, the existing rules do not adequately provide for awareness
    of who is operating in the
    airspace. The FAA is therefore proposing to require the remote
    identification of UAS to enable
    the agency to identify unmanned aircraft flying in the airspace of the
    United States and locate the
    operators of those aircraft. Remote identification equipment would
    provide identifying
    information for UAS similar to how ADS-B and transponders provide
    identifying information
    for manned aircraft. This information would also be essential for the management of the flow of
    air traffic as more UAS integrate into the airspace of the United
    States.
    46
    The FAA does not propose the use of transponders or ADS-B Out for
    remote
    identification for three primary reasons. First, the use of these
    technologies would require
    significant additional infrastructure, including radars and receivers,
    to cover the lower altitudes
    of the airspace of the United States where unmanned aircraft are
    expected to primarily operate.
    Second, the FAA expects that, due to the volume of unmanned aircraft
    operations projected, the
    additional radio frequency signals would saturate the available
    spectrum and degrade the overall
    cooperative surveillance system. Finally, transponders and ADS-B Out
    do not provide any
    information about the location of control stations, as these systems
    were designed for manned
    aircraft. For these reasons, the FAA has determined that existing
    cooperative surveillance
    systems are incapable of supporting UAS remote identification and is
    proposing a new
    cooperative surveillance technology specifically for UAS. However, the
    proposal does not
    prohibit the use of ADS-B In, if the ADS-B In equipment is
    manufactured and installed in
    accordance with FAA requirements and guidance.

    2. Current Challenges with Associating UAS with Their Owners and
    Operators
    All manned aircraft, unmanned aircraft weighing over 0.55 pounds, and
    any unmanned
    aircraft operated pursuant to 14 CFR part 107 or part 91 (irrespective
    of weight) are subject to
    FAA’s aircraft registration and marking requirements. These
    requirements are the fundamental
    means for the FAA to physically identify manned and unmanned aircraft
    operating in the
    airspace of the United States and to associate them with their owners.
    The FAA recognizes that
    current registration and marking requirements are most useful when the
    aircraft is static or when
    information regarding the aircraft and its owner is needed without a
    direct link to the aircraft

    17 See Advisory Circulars 20-172B and 90-114A.
    47
    itself. In the case of unmanned aircraft in flight, however,
    registration and marking alone are
    insufficient to identify the aircraft and to locate the person
    manipulating the flight controls of a
    UAS. This is due to both the small size of most unmanned aircraft and
    to the fact that the person
    manipulating the flight controls of the UAS is not co-located with the aircraft. The Registration
    Rule acknowledged that the registration of small unmanned aircraft
    would provide a means by
    which to quickly identify the aircraft in the event of an incident or
    accident involving a small
    UAS. The Registration Rule also acknowledged that registration of
    small unmanned aircraft
    would provide an immediate and direct opportunity for the FAA to
    educate small UAS owners
    on safety requirements before they begin operating. The Registration
    Rule did not, however,
    envision the use of registration numbers as a means to identify or
    locate the small UAS owner or
    the person manipulating the flight controls of the UAS during
    real-time flight operations.
    The small size of most unmanned aircraft makes it difficult – if not
    impossible – to read
    their registration numbers from the ground, preventing proper
    identification of the unmanned
    aircraft while it is in flight. Although it is true that manned
    aviation faces similar identification
    issues (since aircraft registration marks may be impossible to read
    from the ground when the
    aircraft is flying at certain altitudes or speeds), there is an
    important distinction between manned
    and unmanned aviation that makes the inability to read a registration
    number from the ground
    less problematic in manned aviation. In manned aviation, the
    pilot-in-command is co-located
    with the aircraft and is therefore more easily identifiable, even if
    such identification occurs after
    landing.
    In addition, pilots of manned aircraft are often required to, or
    choose to, maintain
    two-way communications with air traffic control (ATC) for purposes of
    receiving air traffic
    services. This communication helps ascertain the identity and intent
    of the pilot in command.
    48
    Furthermore, transponders and ADS-B Out systems transmit unique codes
    that allow ATC to
    identify and distinguish aircraft from others flying in the airspace
    of the United States, as
    discussed in the preceding section. These means of identification are
    not currently required or
    feasible for UAS. The challenge of identifying UAS would only increase
    with the proliferation
    of BVLOS operations – when pilots will likely be located far away from
    the unmanned aircraft
    location.
    3. Situational Awareness
    The ability to know the location of unmanned aircraft operating in the
    airspace of the
    United States and to identify and locate their operators creates
    situational awareness of
    operations conducted in the airspace of the United States, fosters accountability of the operators
    and owners of UAS, and improves the capabilities of the FAA and law
    enforcement to
    investigate and mitigate careless, hazardous, and noncompliant
    operations. This contributes to
    safety in air commerce and the efficient use of the airspace of the
    United States.
    Remote identification would provide greater situational awareness of
    UAS operating in
    the airspace of the United States to other aircraft in the vicinity of
    those operations and also
    provide information to airport operators. Manned aircraft, especially
    those operating at low
    altitudes where UAS operations are anticipated to be the most
    prevalent, such as helicopters and
    agricultural aircraft, could carry the necessary equipment to display
    the location of UAS
