§ 93.303
Definitions.
For the purposes of this subpart:
Allocation means authorization to
conduct a commercial air tour in the
Grand Canyon National Park (GCNP)
Special Flight Rules Area (SFRA).
Commercial air tour means any flight
conducted for compensation or hire in
a powered aircraft where a purpose of
the flight is sightseeing. If the operator
of a flight asserts that the flight is not
a commercial air tour, factors that can
be considered by the Administrator in
making a determination of whether the
flight is a commercial air tour include,
but are not limited to—
(1) Whether there was a holding out
to the public of willingness to conduct
a sightseeing flight for compensation
or hire;
(2) Whether a narrative was provided
that referred to areas or points of in-
terest on the surface;
(3) The area of operation;
(4) The frequency of flights;
(5) The route of flight;
(6) The inclusion of sightseeing
flights as part of any travel arrange-
ment package; or
(7) Whether the flight in question
would or would not have been canceled
based on poor visibility of the surface.
Commercial Special Flight Rules Area
Operation means any portion of any
flight within the Grand Canyon Na-
tional Park Special Flight Rules Area
that is conducted by a certificate hold-
er that has operations specifications
authorizing flights within the Grand
Canyon National Park Special Flight
Rules Area. This term does not include
operations conducted under an FAA
Form 7711–1, Certificate of Waiver or
Authorization. For more information
on commercial special flight rules area
operations,
see ‘‘Grand Canyon Na-
tional Park Special Flight Rules Area
(GCNP SFRA) Procedures Manual,’’
which is available online or from the
responsible Flight Standards Office.
GCNP quiet aircraft technology des-
ignation means an aircraft that is sub-
ject to § 93.301 and has been shown to
comply with the noise limit specified
in appendix A of this part.
Number of passenger seats means the
number of passenger seats for which an
individual aircraft is configured.
Park means Grand Canyon National
