5. Who can operate in these areas?

Restrictions issued under this section prohibit the operation of any aircraft or device, or any activity within the designated airspace area except in accordance with the authorizations, terms, and conditions of the TFR published in the NOTAM, unless otherwise authorized by: (1) Air Traffic Control; or (2) A Certificate of Waiver or Authorization FAA Form 7711-1 issued for the aerial demonstration by Flight Standards.

Note: ATC must coordinate with the official responsible for the aerial demonstration prior to authorizing VFR or IFR aircraft to operate within the restricted airspace.

6. Can TFRs be requested for an event (or part of an event) that is outside of controlled airspace?

At times it may be necessary to issue restrictions to protect airspace not contained within controlled airspace.

For an aerial demonstration, if any segment of the requested airspace is outside of controlled airspace, a restriction may be issued if the following criteria are met: (1) Military aircraft are conducting aerobatic demonstrations; (2) Civilian aircraft that operate in excess of 200 knots are conducting aerobatic demonstrations; and (3) Parachute demonstration teams are performing.

Note: Aerial demonstrations and sporting events occurring within Class B airspace areas may be handled through existing ATC procedures, without additional restrictions. However, each situation is unique and should be evaluated individually.
