Appendix 3 APPENDIX 3. SPECIAL PROVISIONS

a. Ceiling, visibility, and wind limitations shall be appropriate to the type of exhibitions involved.

, b. Aerobatic maneuvers may not be directed toward any spectator area. Certain related maneuvers and procedures, however, may be authorized as outlined below:

(1) Rolling 360° turns with a segment toward the spectator area, but beyond the required separation from the showline.

(2) "Approved maneuvers" that are completed beyond a point that the rollout and trajectory of the aircraft will not endanger the spectators. "Approved maneuvers" are maneuvers that have been approved by AFS-20 for a specific performer. Upon request from the FAA, performers are required to present evidence of the approval.

(3) For military demonstration teams, approved maneuvers may include level or climbing nonaerobatic flight over designated spectator areas; however, in no case shall the altitude of the aircraft be less than 500 feet Above Ground Level (AGL) over a designated spectator area. All other performers must be at 1,000 feet AGL, or above, over designated spectator areas unless they hold approval for the maneuver from AFS-20.

(4) Maneuvers on an oblique line that pass 500, 1,000, or 1,500 feet, as appropriate, to either side of a spectator area.

c. No aerobatic demonstrations shall be authorized or scheduled during such time as a suspension of airport traffic or diversion of other aircraft traffic will cause a hardship to scheduled air carrier operations.

d. The "arrival demonstration" is not authorized unless an "advance member" of the demonstration team has been briefed on the showline and pertinent special provisions contained in FAA Form 7711-1, Certificate of Waiver or Authorization, and this information has been relayed to the team leader before the arrival demonstration.

e. The following are some examples of facilities that could be required dependent upon the type of aviation event. They must be readily available at the demonstration site.

(1) Ambulance (air and/or ground).

(2) Firetruck.

(3) Crash Wagon.

(4) Physician.

(5) Other equivalent emergency equipment.

If the event is conducted at an airport, a closed field signal in the form of a large "X," colored aviation yellow, and readily visible from 3,000 feet above the surface must be displayed on the landing areas when the aerial demonstration is in progress. The closed field signal is necessary at most uncontrolled airports, but may not be required at FAA controlled facilities.

The holder of the FAA Form 7711-1 shall ensure that roads under the specified flight maneuvering area are devoid of vehicular traffic or spectators.

h. Racing flight operations are not authorized when the reported (or observed) flight visibility is less than
