Section 91.145 Management of aircraft operations in the vicinity of aerial demonstrations and major sporting
events.
(a) The FAA will issue a Notice to
Airmen (NOTAM) designating an area
of airspace in which a temporary flight
restriction applies when it determines
that a temporary flight restriction is
necessary to protect persons or property on the surface or in the air, to
maintain air safety and efficiency, or
to prevent the unsafe congestion of aircraft in the vicinity of an aerial demonstration or major sporting event.
These demonstrations and events may
include:
(1) United States Naval Flight Demonstration Team (Blue Angels);

(11) Indianapolis 500 Mile Race;
(12) Any other aerial demonstration
or sporting event the FAA determines
to need a temporary flight restriction
in accordance with paragraph (b) of
this section.
(b) In deciding whether a temporary
flight restriction is necessary for an
aerial demonstration or major sporting
event not listed in paragraph (a) of this
section, the FAA considers the following factors:
(1) Area where the event will be held.
(2) Effect flight restrictions will have
on known aircraft operations.
(3) Any existing ATC airspace traffic
management restrictions.
(4) Estimated duration of the event.
(5) Degree of public interest.
(6) Number of spectators.
(7) Provisions for spectator safety.
(8) Number and types of participating
aircraft.
(9) Use of mixed high and low performance aircraft.
(10) Impact on non-participating aircraft.
(11) Weather minimums.
(12) Emergency procedures that will
be in effect.
(c) A NOTAM issued under this section will state the name of the aerial
demonstration or sporting event and
specify the effective dates and times,
the geographic features or coordinates,
and any other restrictions or procedures governing flight operations in
the designated airspace.
(d) When a NOTAM has been issued in
accordance with this section, no person
may operate an aircraft or device, or
engage in any activity within the designated airspace area, except in accordance with the authorizations, terms,
and conditions of the temporary flight
restriction published in the NOTAM,
unless otherwise authorized by:
(1) Air traffic control; or
(2) A Flight Standards Certificate of
Waiver or Authorization issued for the
demonstration or event.
(e) For the purpose of this section:
(1) Flight restricted airspace area for an
aerial demonstration - The amount of
airspace needed to protect persons and
property on the surface or in the air, to
maintain air safety and efficiency, or
to prevent the unsafe congestion of aircraft will vary depending on the aerial
