    2
    GARLAND, Chief Judge: The Federal Aviation
    Administration (FAA) has issued a rule that regulates certain
    unmanned aircraft, popularly known as “drones.” Petitioner
    John Taylor, a model aircraft hobbyist, seeks review of that rule.
    He contends that the rule exceeds the agency’s statutory
    authority, is arbitrary and capricious, and has miscellaneous
    additional infirmities. For the following reasons, we deny the
    petition for review.
    I
    In the FAA Modernization and Reform Act of 2012,
    Congress tasked the Secretary of Transportation with developing
    “a comprehensive plan to safely accelerate the integration of
    civil unmanned aircraft systems into the national airspace
    system.” Pub. L. 112-95, § 332(a)(1), 
    126 Stat. 11
    , 73 (codified
    at 
    49 U.S.C. § 40101
     note) (hereinafter “Modernization Act”).
    The Act defines an “unmanned aircraft” as “an aircraft that is
    operated without the possibility of direct human intervention
    from within or on the aircraft.” Modernization Act § 331(8). A
    “small unmanned aircraft” is a craft that meets this definition
    and weighs less than 55 pounds. Id. § 331(6). And an
    “unmanned aircraft system” is “an unmanned aircraft and
    associated elements,” such as communication links and
    components that control the unmanned aircraft. Id. § 331(9).
    Section 332 of the Modernization Act instructs the
    Secretary to conduct a rulemaking “to implement the
    recommendations” of the comprehensive plan, and to issue “a
    final rule on small unmanned aircraft systems that will allow for
    civil operation of such systems in the national airspace system.”
    Id. § 332(b). Section 333 of the Act, entitled “Special Rules for
    Certain Unmanned Aircraft Systems,” directs the Secretary to
    determine whether some unmanned aircraft systems may operate
    safely in the national airspace system before completion of the
    3
    comprehensive plan and rulemaking required by section 332.
    Id. § 333(a).
    Section 333 is one of two sections of the Modernization Act
    that are most directly relevant to this petition. It directs the
    Secretary to determine “(1) which types of unmanned aircraft
    systems, if any, as a result of their size, weight, speed,
    operational capability, proximity to airports and populated areas,
    and operation within visual line of sight do not create a hazard
    to users of the national airspace system or the public or pose a
    threat to national security; and (2) whether a certificate of
    waiver, certificate of authorization, or airworthiness certification
    under [
    49 U.S.C. § 44704
    ] is required for the operation of [such]
    unmanned aircraft systems.” 
    Id.
     § 333(b). If the Secretary
    determines “that certain unmanned aircraft systems may operate
    safely in the national airspace system, the Secretary shall
    establish requirements for the safe operation of such aircraft
    systems in the national airspace system.” Id. § 333(c).
    The other directly relevant section is section 336, which
    creates a statutory “Special Rule for Model Aircraft.” Id. § 336.
    The section defines a “model aircraft” as “an unmanned aircraft
    that is -- (1) capable of sustained flight in the atmosphere;
    (2) flown within visual line of sight of the person operating the
    aircraft; and (3) flown for hobby or recreational purposes.” Id.
    § 336(c). Section 336 provides that, notwithstanding any other
    provision of law regarding incorporation of unmanned aircraft
    systems into FAA plans and policies, the FAA (a component of
    the Department of Transportation) “may not promulgate any rule
    or regulation regarding a model aircraft” that satisfies the
    following five operational criteria:
    (1) the aircraft is flown strictly for hobby or
    recreational use;
    4
    (2) the aircraft is operated in accordance with a
    community-based set of safety guidelines and within
    the programming of a nationwide community-based
    organization;
    (3) the aircraft is limited to not more than 55
    pounds . . . ;
    (4) the aircraft is operated in a manner that does not
    interfere with and gives way to any manned aircraft;
    and
    (5) when flown within 5 miles of an airport, the
    operator of the aircraft provides the airport operator
    and the airport air traffic control tower . . . with prior
    notice of the operation . . . .
    Id. § 336(a).
    Section 336 also provides, however, that nothing in it “shall
    be construed to limit the authority of the [FAA] Administrator
    to pursue enforcement action against persons operating model
    aircraft who endanger the safety of the national airspace
    system.” Id. § 336(b). In short, section 336’s statutory Special
    Rule creates a safe harbor from FAA regulation for those model
    aircraft that meet its five operational criteria. That safe harbor
    itself has an exception for dangerous model aircraft operations.
    For the purposes of this opinion, we will use the phrase
    “section 336 model aircraft” to refer to model aircraft that meet
    the five operational criteria of the statutory Special Rule. We
    will use the term “non-section 336 model aircraft” to refer to
    model aircraft that do not meet one or more of the safe harbor
    requirements.
    5
    After Congress passed the Modernization Act, the FAA
    took two related regulatory actions that are relevant as
    background but are not the subject of this case.
    In 2014, the agency issued an Interpretation of the Special
    Rule for Model Aircraft, which interpreted several terms
    contained in the statutory Special Rule. 
    79 Fed. Reg. 36,172
    (June 25, 2014). The FAA sought public comments on the
    Interpretation and is currently reviewing those comments.
    Status Report, UAS Am. Fund, LLC v. FAA, No. 14-1156 (D.C.
    Cir. June 19, 2018).
    In 2015, the FAA promulgated a rule requiring the
    registration of small unmanned aircraft, including model
    aircraft. Registration and Marking Requirements for Small
    Unmanned Aircraft, 
    80 Fed. Reg. 78,594
     (Dec. 16, 2015).
    Taylor challenged the registration rule, and this circuit held that
    it violated the Modernization Act in certain respects. Taylor v.
    Huerta, 
    856 F.3d 1089
    , 1093 (D.C. Cir. 2017). Soon thereafter,
    Congress restored the registration rule to effect. National
    Defense Authorization Act for Fiscal Year 2018, Pub. L. No.
    115-91, § 1092(d), 
    131 Stat. 1283
    , 1611 (2017).
    Finally, in 2016, the agency promulgated the rule that is the
    subject of this case, Operation and Certification of Small
    Unmanned Aircraft Systems, 
    81 Fed. Reg. 42,064
     (June 28,
    2016) (hereinafter “Small UAS Rule”). Two provisions of the
    Small UAS Rule are at the heart of Taylor’s petition for review.
    First, the rule adds a new part 107 to the Code of Federal
    Regulations (C.F.R.) to “allow for routine civil operation” of
    small unmanned aircraft systems and “to provide safety rules for
    those operations.” 
    Id. at 42,066
    . Consistent with the statutory
    definition noted above, the rule defines a small unmanned
    aircraft as one that weighs less than 55 pounds. 
    Id. at 42
    ,085-
    6
    86; see 
    14 C.F.R. § 107.3
    . To mitigate risk, the rule limits small
    unmanned aircraft systems to “daylight and civil twilight
    operations with appropriate collision lighting, confined areas of
    operation, and visual-line-of-sight operations.” 81 Fed. Reg. at
    42,066; see 
    14 C.F.R. §§ 107.29
    , 107.31, 107.43, 107.45. Part
    107 also addresses “airspace restrictions, remote pilot
    certification, visual observer requirements, and operational
    limits.” 81 Fed. Reg. at 42,066; see, e.g., 
    14 C.F.R. §§ 107.33
    ,
    107.37, 107.41, 107.61.
    Second, the Small UAS Rule adds a new subpart E to part
    101 of the C.F.R., as well as a § 107.1 to part 107. Those
    provisions codify the statutory Special Rule for Model Aircraft
    contained in Modernization Act § 336. Subpart E’s § 101.41
    lists the five operational criteria required to qualify for the
    statutory safe harbor from FAA regulation. 
    14 C.F.R. § 101.41
    .
    Subpart E’s § 101.43 provides that the safe harbor does not
    extend to operations that endanger the safety of the national
    airspace system. Id. § 101.43. And § 107.1 completes the
    package by providing that the small unmanned aircraft system
    requirements of part 107 do not apply to any aircraft that falls
    within the safe harbor of § 101.41. Id. § 107.1(b)(2).1 The
    result is that a section 336 model aircraft -- one that meets the
    five criteria in the statutory Special Rule -- is exempt from the
    new part 107 requirements. By contrast, a model aircraft that
    fails to meet one or more of the section 336 criteria is subject to
    the regulations of part 107.
    1
    Section 107.1 accomplishes this by providing that part 107
    “does not apply to . . . [a]ny aircraft subject to the provisions of part
    101.” Id. § 107.1(b)(2). And § 101.1 states that part 101 “prescribes
    rules governing the operation” of “[a]ny model aircraft that meets the
    conditions specified in § 101.41.” Id. § 101.1(a)(5).
    7
    II
    Taylor has petitioned for review of the Small UAS Rule.
    His challenges fall into four categories, which we address
    below.
    A
    Taylor contends that the rule violates the Modernization Act
    by regulating the forbidden category of section 336 model
    aircraft. As we noted above, section 336(a) of the Act states that
    the FAA “may not promulgate any rule or regulation regarding
    a model aircraft” if that aircraft meets the five operational
    criteria listed in the statute. Modernization Act § 336(a). Taylor
    argues that the rule violates section 336(a) in two respects: by
    imposing new regulations on section 336 model aircraft, and by
    exposing section 336 model aircraft to pre-existing regulations.
    The FAA did not request Chevron deference for its statutory
    interpretation, see Chevron U.S.A. Inc. v. Nat. Res. Def. Council,
    Inc., 
    467 U.S. 837
     (1984). Because we conclude that the
    petition should be denied on de novo review, we do not address
    the Chevron standard. See Fed. Election Comm’n v. Craig for
    U.S. Senate, 
    816 F.3d 829
    , 839 n.6 (D.C. Cir. 2016).
    Taylor’s first argument is that the newly promulgated 
    14 C.F.R. § 101.41
     is a rule or regulation regarding model aircraft
    and is inconsistent with section 336(a). Taylor’s argument fails
    because § 101.41 does not regulate section 336 model aircraft
    at all. To the contrary, it simply defines the model aircraft that
    fall within section 336(a) and, in so doing, does no more than
    repeat the five criteria that Congress itself listed in section
    336(a).
    8
    Section 101.41 states:
    This subpart prescribes rules governing the operation
    of a model aircraft . . . that meets all of the following
    conditions as set forth in section 336 of Public Law
    112–95:
    (a) The aircraft is flown strictly for hobby or
    recreational use;
    (b) The aircraft is operated in accordance with a
    community-based set of safety guidelines and within
    the programming of a nationwide community-based
    organization;
    (c) The aircraft is limited to not more than 55
    pounds . . . ;
    (d) The aircraft is operated in a manner that does not
    interfere with and gives way to any manned aircraft;
    and
    (e) When flown within 5 miles of an airport, the
    operator of the aircraft provides the airport operator
    and the airport air traffic control tower . . . with prior
    notice of the operation.
    
    14 C.F.R. § 101.41
     (emphasis added); compare Modernization
    Act § 336(a). Section 101.43 then subjects model aircraft that
    meet those criteria to only one requirement: the anti-
    endangerment provision expressly permitted by Modernization
    Act § 336. 
    14 C.F.R. § 101.43
    ; see Modernization Act § 336(b).
    And the new § 107.1(b)(2) then exempts model aircraft that
    satisfy the § 101.41 criteria from the regulations imposed by the
    new part 107. 
    14 C.F.R. § 107.1
    (b)(2).
    9
    Accordingly, the Small UAS Rule’s § 101.41 is nothing like
    the Registration Rule that we invalidated in Taylor’s previous
    challenge. See Huerta, 856 F.3d at 1092. The Registration Rule
    “create[d] a new regulatory regime for model aircraft.” Id. at
    1093. It “impose[d] new requirements . . . on people who
    previously had no obligation to . . . the FAA” and “impose[d]
    new penalties . . . on model aircraft owners who [did] not
    comply.” Id. By contrast, § 101.41 simply mirrors the statutory
    category of section 336 model aircraft and imposes no
    requirements on them (except for the anti-endangerment
    requirement permitted by section 336(b)). See Modernization
    Act § 336(b).2
    Taylor’s second claim is that the Small UAS Rule
    unlawfully subjects section 336 model aircraft to pre-existing
    regulations that were previously applicable only to traditional,
    full-size aircraft. According to Taylor, the rule exposes section
    336 model aircraft to the “entire weight of traditional aircraft
    statutes and regulations,” yielding “results that are as legally
    inescapable as they are absurd.” Taylor Br. 24, 25. He claims,
    for example, that all hobbyists must now obtain pilots’ licenses,
    comply with minimum altitude requirements, and service their
    aircraft at licensed aircraft mechanics. Id. at 25-26, 44-47.
    In Taylor’s view, this parade of horribles arises because
    § 107.1(a) states that, “[e]xcept as provided in paragraph (b) of
    this section, this part applies to . . . civil small unmanned aircraft
    systems.” 
    14 C.F.R. § 107.1
    (a). Taylor concludes from this
    language that section 336 model aircraft are to be treated as a
    type of “civil small unmanned aircraft system,” and thus a type
    2
    Of course, a rule that defines the category of aircraft that it does
    not regulate could be described as a rule “regarding” such aircraft.
    But we do not read section 336(a) as barring the FAA from advising
    operators which aircraft are not subject to the Small UAS Rule.
    10
    of “aircraft,” for all statutory and regulatory purposes. Taylor
    Br. 24.
    This reads too much into the rule’s reference to “civil small
    unmanned aircraft systems.” As noted above, none of the new
    requirements of part 107 apply to section 336 model aircraft at
    all. That is because the “paragraph (b)” exception referred to in
    the above quotation states that “[t]his part does not apply to . . .
    [a]ny aircraft subject to the provisions of part 101,” 
    14 C.F.R. § 107.1
    (b)(2), and § 101.41 mirrors the section 336(a) criteria,
    see id. § 101.41; supra note 1.
    Nor does any other part of the Small UAS Rule subject
    section 336 model aircraft to the pre-existing regulations Taylor
    identifies. To the contrary, in the rule’s preamble, the FAA
    explained that it had not proposed “any changes to its existing
    regulations with regard to section 336 operations” and that such
    changes were beyond the scope of the rulemaking. 81 Fed. Reg.
    at 42,083. The challenged rule itself, therefore, imposes no
    restrictions on section 336 model aircraft apart from the anti-
    endangerment regulation, 
    14 C.F.R. § 101.43
    , which Taylor
    does not challenge.3 At oral argument, the FAA agreed with this
    interpretation.4 Accordingly, because Taylor’s petition for
    3
    Taylor does not challenge the FAA’s authority to promulgate
    the anti-endangerment regulation for good reason. As noted in Part I,
    the statutory Special Rule contains an exception to the section 336(a)
    regulatory bar for this type of FAA regulation. See Modernization Act
    § 336(b) (“Nothing in this section shall be construed to limit the
    authority of the Administrator to pursue enforcement action against
    persons operating model aircraft who endanger the safety of the
    national airspace system.”).
    4
    Oral Arg. Recording at 48:20-48:57 (Court: “Do you regard
    anything that the agency did in the rulemaking that is challenged here
    as imposing any regulations on model aircraft that satisfy the statute’s
    11
    review was limited to the Small UAS Rule, see Pet. for Rev.,
    Taylor v. FAA, No. 16-1302 (D.C. Cir. Aug. 29, 2016), he will
    have to file a new petition should he ever wish to challenge an
    attempt by the FAA to apply a pre-existing rule to section 336
    model aircraft.
    Because the challenged rule’s only regulation of section 336
    model aircraft is permitted by the Modernization Act, the FAA
    has honored the statutory safe harbor for these aircraft. We
    therefore reject this challenge.
    B
    Taylor’s next contention concerns the FAA’s statutory
    authority to regulate non-section 336 model aircraft. Unlike
    section 336 model aircraft, these recreational aircraft fall outside
    the statutory (and regulatory) safe harbor and are subject to the
    new operating requirements of part 107.5 Taylor argues that the
    FAA lacks statutory authority to regulate non-section 336 model
    aircraft.
    According to Taylor, prior to passage of the Modernization
    Act, “the FAA consistently acknowledged it did not have
    regulatory authority over recreational model aircraft.” Taylor
    Br. 30. Taylor maintains that, at the time the Modernization Act
    336 requirements?” FAA Counsel: “No.” Court: “No requirements
    of any kind?” Counsel: “No. . . . There is a regulation that prohibits
    reckless operations, but . . . 336(b) expressly permits FAA to prevent
    reckless operation even of model aircraft.”).
    5
    Part 107 applies to “civil small unmanned aircraft systems”
    except, as relevant here, to “[a]ny aircraft subject to the provisions of
    part 101.” 
    14 C.F.R. § 107.1
     (a), (b)(2). Because only those model
    aircraft that meet all of the section 336(a) criteria are subject to part
    101, part 107 governs model aircraft that do not meet those criteria.
    12
    was passed, the FAA’s interpretation of the pre-existing Federal
    Aviation Act was that only “commercial use small unmanned
    vehicles” were aircraft; recreational model aircraft, by contrast,
    were not “aircraft” at all. 
    Id.
     Moreover, he continues, the
    Modernization Act “codified” that FAA interpretation. 
    Id.
     The
    FAA disputes Taylor’s claims about its previous interpretation,
    stating that its previous failure to regulate recreational model
    aircraft was an exercise of enforcement discretion, not statutory
    interpretation. See Operation and Certification of Small
    Unmanned Aircraft Systems, 
    80 Fed. Reg. 9544
    , 9550 (proposed
    Feb. 23, 2015); FAA Br. 43-44.
    We do not need to resolve the parties’ dispute about the
    FAA’s previous interpretation of the pre-existing statutory
    provisions, or their dispute about whether those provisions alone
    would have been sufficient to authorize the Small UAS Rule.
    The primary authority upon which the FAA relies for that rule
    is a new statutory section: section 333 of the Modernization
    Act, passed in 2012. See 81 Fed. Reg. at 42,067 n.6. And there
    is no doubt that this section permits the agency to apply the
    regulations of the Small UAS Rule to recreational model aircraft
    that do not fall within the section 336 safe harbor.
    Modernization Act § 333 directs the FAA to determine
    “which types of unmanned aircraft . . . may operate safely in the
    national airspace system,” and then directs the agency to
    “establish requirements for the safe operation of such aircraft.”
    Modernization Act § 333(b), (c). Section 336, in turn, defines
    a “model aircraft” as “an unmanned aircraft that is . . . flown for
    hobby or recreational purposes.”               Modernization Act
    § 336(c)(3) (emphases added). And it provides that the FAA
    may not promulgate regulations regarding “a model aircraft . . .
    if . . . the aircraft” satisfies the five operational criteria of the
    safe harbor. Id. § 336(a) (emphasis added). Thus, the text
    makes clear that Congress has authorized the FAA to regulate
    13
    recreational model aircraft, so long as they are outside the safe
    harbor of section 336(a).6
    There is nothing to support Taylor’s contention that,
    notwithstanding the above, the Modernization Act was intended
    to codify the alleged prior understanding that the FAA could not
    regulate any recreational model aircraft.7 To begin, we note that
    Taylor has cited neither statutory language nor legislative
    history that indicates such an intent. It is true, as Taylor notes,
    that “Congress is presumed to be aware of an administrative . . .
    interpretation of a statute and to adopt that interpretation when
    it re-enacts a statute without change.” Lorillard v. Pons, 
    434 U.S. 575
    , 580 (1978). But even if we were to accept Taylor’s
    claim regarding the FAA’s interpretation of pre-existing
    statutory provisions, Congress did not re-enact a statute without
    change here. To the contrary, it enacted a new statute with
    6
    The statutory text likewise contradicts Taylor’s contention that
    an aircraft is solely “a tool of manned flight, used, by a person, to
    achieve that person’s flight.” Taylor Br. 31 n.16. At least with respect
    to the Modernization Act, “aircraft” includes “unmanned aircraft.”
    See Modernization Act § 331(8).
    7
    In Taylor v. Huerta, we did say that section 336(a) “codified the
    FAA’s longstanding hands-off approach to the regulation of model
    aircraft.” 856 F.3d at 1091. But that codification extended only to
    model aircraft falling within the safe harbor of section 336(a). The
    problem with the Registration Rule at issue in Huerta was that it
    applied to all model aircraft, not just to model aircraft outside the safe
    harbor. See id. at 1092; see also Order, Taylor v. Huerta, No. 15-1495
    (D.C. Cir. Aug. 3, 2017) (denying petitioner’s motion for a contempt
    sanction against the FAA for applying registration requirements to
    non-section 336 model aircraft).
    14
    entirely new provisions regarding the regulation of unmanned
    aircraft.8
    Taylor insists that the structure of the Modernization Act
    indicates that Congress “adopted the FAA’s [allegedly]
    consistent interpretation that recreational model aircraft are
    neither ‘civil aircraft’ nor ‘public aircraft’ (the only two types of
    aircraft that exist),” and that, as such, “they are not aircraft at
    all.” Taylor Br. 35 (citing 
    49 U.S.C. § 40102
    (a)(16)). He
    argues that the structure so indicates because it “create[s]
    separate regimes for: 1) civil unmanned aircraft, in § 332 and
    § 333; 2) public unmanned aircraft, in § 334; and 3) recreational
    model aircraft, in § 336.” Id. at 34-35. We disagree.
    First, the suggestion that recreational model aircraft are
    neither “public” nor “civil” aircraft, and hence “not aircraft at
    all,” is at best a counterintuitive interpretation of the pre-existing
    statutory definition.9 In any event, the contention that a model
    aircraft is not an “aircraft” for purposes of the Modernization
    Act is directly contradicted by the Act itself, which, as we have
    just noted, defines “model aircraft” as “an unmanned aircraft
    that is . . . flown for hobby or recreational purposes.”
    Modernization Act § 336(c)(3); see id. § 331(8) (defining
    “unmanned aircraft” as a type of “aircraft”).
    8
    Nor did it merely “adopt[] a new law incorporating sections of
    a prior law.” Lorillard, 
    434 U.S. at 581
    .
    9
    Section 40102(a) defines an “aircraft” as “any contrivance . . .
    designed to navigate, or fly in, the air.” 
    49 U.S.C. § 40102
    (a)(6). It
    defines a “public aircraft” as a government aircraft.              
    Id.
    § 40102(a)(41). And it then defines a “civil aircraft” as “an aircraft
    except a public aircraft.” Id. § 40102(a)(16).
    15
    Second, the Act does not create the three separate regimes
    that Taylor perceives. Section 332 does apply to “civil
    unmanned aircraft,” and section 334 does apply to “public
    unmanned aircraft.” Id. §§ 332, 334. But section 333 (which is
    the directly relevant section here and directs expedited
    rulemaking) simply applies to “certain unmanned aircraft” --
    those the FAA determines may operate safely in the national
    airspace system. Id. § 333.
    Nor does section 336 constitute a statutory bar against any
    regulation of recreational model aircraft. As set forth above,
    that section provides that the FAA may not promulgate
    regulations regarding “a model aircraft . . . if . . . the aircraft”
    satisfies the five operational criteria of the safe harbor. Id.
    § 336(a) (emphasis added). The expressio unius est exclusio
    alterius canon -- “the expression of one thing implies the
    exclusion of others” -- suggests that the FAA may promulgate
    regulations if an aircraft does not satisfy those criteria.10 And
    while that canon’s “force in particular situations depends
    entirely on context,” In re Sealed Case No. 97-3112, 
    181 F.3d 128
    , 132 (D.C. Cir. 1999) (en banc) (internal quotation marks
    omitted), here the context indicates that Congress expected that
    10
    Cf. Jennings v. Rodriguez, 
    138 S. Ct. 830
    , 844 (2018) (holding
    that a statutory provision authorizing release from detention in certain
    circumstances implies that there are no other circumstances under
    which individuals detained under the provision may be released);
    POM Wonderful LLC v. Coca-Cola Co., 
    134 S. Ct. 2228
    , 2238 (2014)
    (“By taking care to mandate express pre-emption of some state laws,
    Congress if anything indicated it did not intend the [statute] to
    preclude requirements arising from other sources.”); In re Sealed Case
    No. 97-3112, 
    181 F.3d 128
    , 132 (D.C. Cir. 1999) (en banc) (applying
    the canon to conclude that a Sentencing Guidelines section providing
    “that if the government moves the court may depart [from the
    Guidelines],” means, in context, “that if the government does not
    move the court may not depart”).
    16
    a model aircraft would be subject to regulation if it did not come
    within the safe harbor. After all, why would Congress go to the
    trouble of defining (by listing five criteria) a protected
    subcategory of “model aircraft” if it thought the FAA had no
    authority to regulate model aircraft at all?
    Finally, although we hold that the FAA has authority to
    apply the part 107 requirements to recreational model aircraft
    outside the safe harbor (that is, to non-section 336 model
    aircraft), we do not decide whether the agency may apply any
    other regulations to these aircraft. We do not read part 107 -- or
    anything else that the FAA promulgated in the Small UAS Rule
    that is the sole subject of the petition before us -- to make other
    regulatory provisions applicable to these recreational model
    aircraft, except for those provisions expressly cross-referenced
    in the rule. See, e.g., 
    14 C.F.R. § 107.27
     (requiring compliance
    with 
    14 C.F.R. §§ 91.17
     and 91.19). At oral argument, the FAA
    again agreed with this reading.11 If the FAA were to apply
    other, pre-existing regulatory provisions to non-section 336
    model aircraft, that decision may be subject to a separate
    challenge.12
    11
    Oral Arg. Recording at 53:46-54:09 (Court: “In your view, the
    only -- the only requirements that apply to unmanned aircraft that
    don’t meet 336 are those contained in 107, [is] that right?” FAA
    Counsel: “That’s right . . . to be clear, it’s a subset of operations, so
    . . . it has to be during the day, you have to have visual line of sight
    observer, all of those things.”).
    12
    Because those pre-existing regulations and the statutory
    provisions upon which they were based (including their definition of
    “aircraft”) are not before us, we do not address Taylor’s complaint
    that, by deferring consideration of how such regulations and
    provisions apply to recreational unmanned aircraft systems, the FAA
    rendered those regulations and provisions arbitrary, capricious, or
    unconstitutionally vague.
    17
    C
    We turn next to Taylor’s contention that the Small UAS
    Rule is “arbitrary and capricious.” Taylor Br. 40 (citing 
    5 U.S.C. § 706
    (2)(A)). Under the familiar “arbitrary or
    capricious” standard for reviewing agency action, the scope of
    our review is “narrow,” and we will not “substitute [our]
    judgment for that of the agency.” Motor Vehicle Mfrs. Ass’n v.
    State Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983). Agency
    action survives such review as long as the agency “examine[d]
    the relevant data and articulate[d] a satisfactory explanation for
    its action including a rational connection between the facts
    found and the choice made.” 
    Id.
     (internal quotation marks
    omitted). Taylor’s five arguments do not persuade us that the
    FAA acted arbitrarily or capriciously in this matter.
    1. Taylor first asserts that the Small UAS Rule creates
    “absurd and contradictory results [by] applying full-size aircraft
    regulations” to model aircraft. Taylor Br. 41. We reject this
    challenge because the rule does not do so. As explained above,
    the Small UAS Rule does not apply any regulations to section
    336 model aircraft except the anti-endangerment regulation.
    Nor does the rule apply full-size aircraft regulations to non-
    section 336 model aircraft. As also explained above, the only
    regulations the rule applies to such aircraft are those in (and
    referenced in) the new part 107, which was specifically crafted
    for small unmanned aircraft.13
    13
    We do not understand Taylor to be charging that the small
    unmanned aircraft regulations of part 107 are themselves “absurd and
    contradictory” as applied to non-section 336 model aircraft. In any
    event, his briefs do not do so with sufficient specificity for us to
    discern such a charge. The FAA crafted the regulations of part 107
    because it recognized that pre-existing regulations did “not
    differentiate between manned and unmanned aircraft” and hence could
    18
    2. So far as Taylor challenges the FAA’s decision to
    regulate recreational non-section 336 model aircraft at all, rather
    than limiting its regulations solely to commercial (non-
    recreational) craft, the FAA appropriately accounted for that
    choice. The agency explained that, “from a safety point of view,
    there is no difference between the risk posed by recreational
    operations . . . and non-recreational . . . operations.” 81 Fed.
    Reg. at 42,081. In particular, the agency was concerned that an
    unmanned aircraft operator would not have the ability to see and
    avoid other aircraft, and that a loss of positive control of the
    aircraft could pose a risk to persons, property, and other aircraft.
    Id. at 42,068. Because “[t]here is no data indicating that a small
    UAS operation whose operational parameters raise the safety
    risks addressed by part 107 would become safer simply as a
    result of being conducted for recreational or salutary purposes,”
    id. at 42,081, the agency’s decision to regulate recreational non-
    section 336 model aircraft was reasonable.
    3. Taylor also argues that the agency arbitrarily changed its
    position regarding the regulation of recreational model aircraft.
    In Taylor’s view, the agency historically treated such aircraft as
    “toys . . . rather than as a type of ‘aircraft’” subject to the FAA’s
    statutory authority. Taylor Br. 11. He contends that the Small
    UAS “Rule’s application of [p]art 107 . . . to recreational [non-
    section 336] model aircraft” thus marks a “radical change” that
    the agency cannot lawfully ignore. Id. at 43-44; see FCC v. Fox
    Television Stations, Inc., 
    556 U.S. 502
    , 515 (2009) (“An agency
    may not . . . depart from a prior policy sub silentio or simply
    disregard rules that are still on the books.”).
    result in an “undue burden” on small unmanned aircraft operations.
    81 Fed. Reg. at 42,069. The part 107 provisions were specifically
    “designed to impose the minimal burden necessary to ensure the safety
    and security of a small UAS operation.” Id. at 42,082.
    19
    Once again, it is unnecessary for us to wade into the
    agency’s historical practice because the “primary authority” for
    the rule was a new statute, the Modernization Act. 81 Fed. Reg.
    at 42,067 n.6 (noting that the agency relied primarily on section
    333 of the Act, as well as on other FAA statutory authorities).
    It is true that a new law does not necessarily give an agency a
    blank check to depart from prior policies. See Am. Fed’n of
    Labor & Cong. of Indus. Orgs. v. Brock, 
    835 F.2d 912
    , 917-18
    (D.C. Cir. 1987) (rejecting an agency’s assertion that its
    “dramatic shift” in policy reflected a “contemporaneous
    interpretation of new legislation” where the new legislation
    “made absolutely no alteration to the statutory mandate”
    underlying the policy). But as we have discussed, in this case
    the Modernization Act directed the FAA to establish
    requirements for the safe operation of unmanned aircraft
    systems, including recreational model aircraft outside the safe
    harbor. See supra Section II.B. Congress’ directive to integrate
    such aircraft into the national airspace system adequately
    supports any shift in the FAA’s policy toward recreational non-
    section 336 model aircraft that is reflected in the Small UAS
    Rule.
    4. Taylor further contends that the agency acted arbitrarily
    and capriciously by imposing a notice requirement on operators
    of section 336 model aircraft. Specifically, he objects to the
    requirement that model aircraft operators who want an
    exemption from part 107 must “provide[] [an] airport operator
    and the airport air traffic control tower . . . with prior notice of
    the operation” when flying within five miles of the airport. 
    14 C.F.R. § 101.41
    (e). This requirement is arbitrary, he maintains,
    because the agency does not require similar notice by part 107
    operators. Taylor Br. 48 (citing 
    14 C.F.R. § 107.43
    ).
    We reject Taylor’s argument because it is the statute, not
    the regulation, that imposes the notice requirement. See
    20
    Modernization Act § 336(a)(5).              As we have said,
    Modernization Act § 336(a) lists five operational criteria,
    including the notice requirement, that model aircraft must satisfy
    to fall within the statutory safe harbor. Section 101.41 faithfully
    tracks those requirements, including the notice requirement.
    Compare 14 C.F.R § 101.41(e), with Modernization Act
    § 336(a)(5). And we decline to strike down a rule that merely
    implements an unchallenged governing statute. See AT&T
    Corp. v. Iowa Utilities Bd., 
    525 U.S. 366
    , 396 (1999) (“[I]t is
    hard to declare the FCC’s rule unlawful when it tracks the
    pertinent statutory language almost exactly.”); see also Purepac
    Pharm. Co. v. Friedman, 
    162 F.3d 1201
    , 1205 (D.C. Cir. 1998);
    Metro. Wash. Airports Auth. Prof’l Fire Fighters Ass’n v.
    United States, 
    959 F.2d 297
    , 300 (D.C. Cir. 1992).
    5. Fifth, we reject Taylor’s contention that the FAA acted
    unreasonably by declining to define certain terms in the Small
    UAS Rule. Taylor maintains that the FAA should have clarified
    what makes an organization a “nationwide community-based
    organization,” what qualifies as “programming,” and what
    activities “endanger the safety of the national airspace.” See 
    14 C.F.R. §§ 101.41
    (b), 101.43. The first two terms are part of one
    of the criteria for the safe harbor exemption from part 107, 
    id.
    § 101.41(b); the third is the anti-endangerment provision
    applicable to section 336 model aircraft, id. § 101.43. All three
    precisely mirror the language of section 336 of the
    Modernization Act.
    In the notice accompanying the Small UAS Rule, the FAA
    stated that “issues concerning the specific meaning of section
    336 (such as what makes an organization a nationwide
    community-based organization) are beyond the scope of this
    rule.” 81 Fed. Reg. at 42,082. The agency explained that it was
    “considering the specific meaning of section 336 provisions in
    a separate regulatory action,” and that, “in order to avoid
    21
    duplication, [it] limited the scope of the model-aircraft
    component of th[e] rulemaking simply to codifying the FAA’s
    enforcement authority over model-aircraft operations that
    endanger the safety” of the national airspace. Id.
    The “separate regulatory action” to which the agency
    referred was the proceeding for issuance of an Interpretation of
    the Special Rule for Model Aircraft. See 
    79 Fed. Reg. 36,172
    (June 25, 2014); supra Part I. The initial interpretation, issued
    in 2014, did in fact interpret several terms in section 336,
    including several of interest to Taylor. See 79 Fed. Reg. at
    36,174 (identifying Congress’ intended definition of
    “nationwide community-based organization”); id. n.7
    (explaining that “community-based organizations” include
    groups such as the Academy of Model Aeronautics); see also 81
    Fed. Reg. at 42,124 (identifying the Academy of Model
    Aeronautics as a nationwide community-based organization).
    The initial interpretation also discussed the scope of the FAA’s
    enforcement authority against operators who endanger the safety
    of the national airspace system. 79 Fed. Reg. at 36,175-76. As
    we noted in Part I, the FAA sought public comments on the
    initial interpretation and is currently reviewing those comments.
    Petitions for review challenging the initial interpretation, filed
    in this circuit, have been held in abeyance pending issuance of
    a final interpretive rule. See Order, UAS Am. Fund, LLC v. FAA,
    No. 14-1156 (D.C. Cir. Nov. 18, 2014).
    Contrary to Taylor’s complaint, it was not unreasonable (or
    unconstitutional) for the FAA to use the instant rulemaking
    merely to codify section 336 and to consider the specific
    meaning of section 336’s provisions in the separate regulatory
    action that it had already begun. “An agency enjoys broad
    discretion in determining how best to handle related, yet
    discrete, issues in terms of . . . priorities” and “need not solve
    every problem before it in the same proceeding.” Mobil Oil
    22
    Expl. & Producing Se. Inc. v. United Distrib. Cos., 
    498 U.S. 211
    , 230-31 (1991).14 In announcing the Small UAS Rule, the
    FAA explained that it had “received over 33,000 public
    comments” on the initial interpretation and was “currently
    considering the issues raised by these commenters and will issue
    a final Interpretive Rule that reflects its consideration.” 81 Fed.
    Reg. at 42,082. Delaying issuance of the Small UAS Rule until
    it finalized the interpretive rule, the FAA said, “would prejudice
    non-model small UAS operations.” Id. at 42,083. In light of
    these considerations -- coupled with the Modernization Act’s
    directive to expedite rulemaking for unmanned aircraft systems
    where possible, see Modernization Act §§ 332(b), 333 -- it was
    reasonable for the agency to place further definition of those
    terms in a holding pattern while it landed the Small UAS Rule.
    We therefore reject all of Taylor’s “arbitrary and
    capricious” challenges to the rule.
    D
    Finally, Taylor contends that the FAA violated the
    Paperwork Reduction Act (PRA), 
    44 U.S.C. §§ 3501
     et seq.
    That Act requires agencies to follow specific procedures prior to
    “conduct[ing] or sponsor[ing] the collection of information,”
    including publishing notice in the Federal Register and obtaining
    approval from the Office of Management and Budget (OMB).
    
    Id.
     § 3507(a).
    14
    See Am. Bird Conservancy, Inc. v. FCC, 
    516 F.3d 1027
    , 1032
    (D.C. Cir. 2008); cf. Charter Commc’ns, Inc. v. FCC, 
    460 F.3d 31
    , 43
    (D.C. Cir. 2006) (holding that “[t]he FCC has discretion ‘to defer
    consideration of particular issues to future proceedings when it thinks
    that doing so would be conducive to the efficient dispatch of business
    and the ends of justice’” (quoting U.S. Telecom Ass’n v. FCC, 
    359 F.3d 554
    , 588 (D.C. Cir. 2004))).
    23
    According to Taylor, the agency did not follow the required
    procedures before mandating that operators of section 336(a)
    model aircraft provide notice to airports. As we have explained,
    however, that notification provision is one of the five statutory
    criteria required of operators who wish to take advantage of the
    safe harbor provided by section 336(a). See supra Part II.C.4.
    The FAA’s regulation merely repeats that criterion, without any
    elaboration or specification of the form of notice required.
    Hence, the PRA is inapplicable because it was Congress, not the
    agency, that made notification a prerequisite for entry into the
    safe harbor. Compare Saco River Cellular, Inc. v. FCC, 
    133 F.3d 25
    , 32 (D.C. Cir. 1998) (holding that the FCC was required
    to comply with the PRA where “Congress merely authorized,
    [but] did not require” the collection of information).
    Taylor also faults the FAA for failing to follow PRA
    procedures for the B4UFLY smartphone application, an app
    designed to give unmanned aircraft operators real-time
    information about flight restrictions and other requirements.
    Because B4UFLY was not part of the challenged Small UAS
    Rule, it is beyond the scope of the petition for review that is now
    before us. We note, however, the FAA’s representation that
    PRA procedures were in fact followed and that OMB approved
    the collection of information with respect to B4UFLY. FAA Br.
    48. We also note Taylor’s failure to dispute the point in his
    reply brief.
    III
    The FAA has promulgated a rule that regulates section 336
    model aircraft only to the extent expressly permitted by
    Congress. The rule regulates recreational non-section 336
    model aircraft more broadly, but that regulation is likewise
    consistent with Congressional directives. Because the rule is
    24
    within the agency’s statutory authority and is neither arbitrary
    nor capricious, the petition for review is
    Denied.
