§ 91.144
Temporary restriction on
flight operations during abnormally
high barometric pressure condi-
tions.
(a)
Special flight restrictions.
When any
information indicates that barometric
pressure on the route of flight cur-
rently exceeds or will exceed 31 inches
of mercury, no person may operate an
aircraft or initiate a flight contrary to
the requirements established by the
Administrator and published in a No-
tice to Airmen issued under this sec-
tion.
(b)
Waivers.
The Administrator is au-
thorized to waive any restriction
issued under paragraph (a) of this sec-

livered to isolated communities, where
the operation can be conducted with an
acceptable level of safety.

§ 91.145
Management of aircraft oper-
ations in the vicinity of aerial dem-
onstrations 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 prop-
erty on the surface or in the air, to
maintain air safety and efficiency, or
to prevent the unsafe congestion of air-
craft in the vicinity of an aerial dem-
onstration or major sporting event.
These demonstrations and events may
include:
(1) United States Naval Flight Dem-
onstration Team (Blue Angels);
(2) United States Air Force Air Dem-
onstration Squadron (Thunderbirds);
(3) United States Army Parachute
Team (Golden Knights);
(4) Summer/Winter Olympic Games;
(5) Annual Tournament of Roses
Football Game;
(6) World Cup Soccer;
(7) Major League Baseball All-Star
Game;
(8) World Series;
(9) Kodak Albuquerque International
Balloon Fiesta;
(10) Sandia Classic Hang Gliding
Competition;
(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 fol-
lowing 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 per-
formance aircraft.
(10) Impact on non-participating air-
craft.
(11) Weather minimums.
(12) Emergency procedures that will
be in effect.
(c) A NOTAM issued under this sec-
tion 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 proce-
dures 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 des-
ignated airspace area, except in accord-
ance 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 air-
craft will vary depending on the aerial
