Is that the latest version? The most recent I can find is different, and 44809 appears to be the knowledge test.
Text - S.1405 - 115th Congress (2017-2018): Federal Aviation Administration Reauthorization Act of 2017
SEC. 2128. SPECIAL RULES FOR MODEL AIRCRAFT.
    (a) In General.--Chapter 448, as amended by section 2127 of this
Act, is further amended by inserting after section 44807 the following:
``Sec. 44808. Special rules for model aircraft
    ``(a) In General.--Except as provided in subsection (d), and
notwithstanding any other provision of law relating to the
incorporation of unmanned aircraft systems into Federal Aviation
Administration plans and policies, including this chapter, the
Administrator of the Federal Aviation Administration may not promulgate
any new rule or regulation regarding an unmanned aircraft operating as
a model aircraft or an unmanned aircraft being developed as a model
aircraft if--
            ``(1) the aircraft is flown strictly for hobby or
        recreational use;
            ``(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) not flown beyond the visual line of sight of persons
        co-located with the operator or in direct communication with
        the operator;
            ``(4) the aircraft is operated in a manner that does not
        interfere with and gives way to any manned aircraft;
            ``(5) when flown within 5 miles of an airport, the operator
        of the aircraft provides the airport operator, where
        applicable, and the airport air traffic control tower (when an
        air traffic facility is located at the airport) with prior
        notice of the operation (model aircraft operators flying from a
        permanent location within 5 miles of an airport should
        establish a mutually agreed upon operating procedure with the
        airport operator and the airport air traffic control tower
        (when an air traffic facility is located at the airport)),
        unless the Administrator determines approval should be
        required;
            ``(6) the aircraft is flown from the surface to not more
        than 400 feet in altitude, except under special conditions and
        programs established by a community-based organization; and
            ``(7) the operator has passed an aeronautical knowledge and
        safety test administered by the Federal Aviation Administration
        online for the operation of unmanned aircraft systems subject
        to the requirements of section 44809 or developed and
        administered by the community-based organization and maintains
        proof of test passage to be made available to the Administrator
        or law enforcement upon request.
    ``(b) Updates.--
            ``(1) In general.--The Administrator, in collaboration with
        government and industry stakeholders, including nationwide
        community-based organizations, shall initiate a process to
        update the operational parameters under subsection (a), as
        appropriate.
            ``(2) Considerations.--In updating an operational parameter
        under paragraph (1), the Administrator shall consider--
                    ``(A) appropriate operational limitations to
                mitigate aviation safety risk and risk to the
                uninvolved public;
                    ``(B) operations outside the membership,
                guidelines, and programming of a nationwide community-
                based organization;
                    ``(C) physical characteristics, technical
                standards, and classes of aircraft operating under this
                section;
                    ``(D) trends in use, enforcement, or incidents
                involving unmanned aircraft systems; and
                    ``(E) ensuring, to the greatest extent practicable,
                that updates to the operational parameters correspond
                to, and leverage, advances in technology.
            ``(3) Savings clause.--Nothing in this subsection shall be
        construed as expanding the authority of the Administrator to
        require operators of model aircraft under the exemption of this
        subsection to be required to seek permissive authority of the
        Administrator prior to operation in the national airspace
        system.
    ``(c) Statutory Construction.--Nothing in this section shall be
construed to limit the authority of the Administrator to pursue
enforcement action against persons operating model aircraft.
    ``(d) Exceptions.--The Administrator may promulgate rules relating
to the registration and marking of model aircraft.
    ``(e) Model Aircraft Defined.--In this section, the term `model
aircraft' means an unmanned aircraft that--
            ``(1) is capable of sustained flight in the atmosphere; and
            ``(2) is limited to weighing less than 55 pounds, including
        the weight of anything attached to or carried by the aircraft,
        unless otherwise approved through a design, construction,
        inspection, flight test, and operational safety program
        administered by a community-based organization.''.
