Sec. 161.5 Definitions.
For the purposes of this part, the following definitions apply:
Agreement means a document in writing signed by the airport
operator; those aircraft operators currently operating at the airport
that would be affected by the noise or access restriction; and all
affected new entrants planning to provide new air service within 180
days of the effective date of the restriction that have submitted to the
airport operator a plan of operations and notice of agreement to the
restriction.
Aircraft operator, for purposes of this part, means any owner of an
aircraft that operates the aircraft, i.e., uses, causes to use, or
authorizes the use of the aircraft; or in the case of a leased aircraft,
any lessee that operates the aircraft pursuant to a lease. As used in
this part, aircraft operator also means any representative of the
aircraft owner, or in the case of a leased aircraft, any representative
of the lessee empowered to enter into agreements with the airport
operator regarding use of the airport by an aircraft.
Airport means any area of land or water, including any heliport,
that is used or intended to be used for the landing and takeoff of
aircraft, and any appurtenant areas that are used or intended to be used
for airport buildings or other airport facilities or rights-of-way,
together with all airport buildings and facilities located thereon.
Airport noise study area means that area surrounding the airport
within the noise contour selected by the applicant for study and must
include the noise contours required to be developed for noise exposure
maps specified in 14 CFR part 150.
Airport operator means the airport proprietor.
Aviation user class means the following categories of aircraft
operators: air carriers operating under parts 121 or 129 of this
chapter; commuters and other carriers operating under part 135 of this

aircraft operations; a noise budget or noise allocation program that

hours of operations; a program of airport-use charges that has the
direct or indirect effect of controlling airport noise; and any other
limit on Stage 2 or Stage 3 aircraft that has the effect of controlling
airport noise. This definition does not include peak-period pricing

operations with airport capacity.
