Appendix 1 Figure 16. Instructions for Completion of FAA Form 7711-2 PREPARING FAA FORM 7711-2. Items from the form are discussed below for purposes of clarity and uniformity of its use.

a. Items 1 and 2, Name of Organization/Name of Responsible Person. If you are a representative of an organization, then the organization's name should appear in Item 1 and your name, as the organization's representive, for application purposes should appear in Item 2. If you are not representing an organization, the term N/A should be entered in Item 1 and the applicant's name in Item 2.

b. Item 3, Permanent Mailing Address. Self-explanatory.

c. Item 4, FAR Section and Number to be Waived.

(1) All applicable FAR sections and numbers must be listed in this item. If you are unsure which FAR sections have to be waived, consult the FSDO for guidance before filling out this section.

An application for a parachuting operation should state that authorization is requested in accordance with FAR §§ 105.15 or 105.19.

Item 5, Detailed Description of Proposed Operation. It is sufficient to use the terms "airshow," "aerobatic contest," "aerobatic practice area," "parachute demonstration jump," or "air race" to describe the

e. Item 6, Area of Operation. The description must depict the flight maneuvering area as a cubic or cylindrical cell of airspace, e.g., "a rectangle bounded by the N/S runway (or other definable geographical reference) and a point 5,000 feet east from the surface to 7,000 feet." At off-airport sites, the boundaries should be described using easily identifiable landmarks. Current, properly marked charts, maps, drawings, or photographs of the area of operation (not required for parachute demonstration jumps at aviation events) must accompany the application. The FAA recommends that sponsors use a 7.5 series Topographic Quadrangle Map, published by the U.S. Geological Survey (Scale 1:24,000). Any depiction submitted must include toscale indications of the flight lines, showlines, race courses, the location of the aviation event control point, police dispatch, ambulance, and firefighting equipment. Photographs and to-scale diagrams may be submitted as supplemental material to aid in the FAA's evaluation of a particular site. All flight operations conducted under the waiver shall be limited to the area defined in the FAA-approved application.

f. Item 7, Time Period. List the dates requested for the aviation event and for any press previews that are scheduled. Alternate event dates should also be included in this item.

g. Item 8, Aircraft Make and Model. If the type of aircraft and/or the names of the pilots are not known at the time the application is submitted, the FAA shall accept the application with a statement, "list of aircraft and/or pilot's names will be furnished on [date.]" Once the list has been supplied, last-minute substitutions (parachutists or pilots) must show appropriate qualifications to the FAA inspector-in-charge at the aviation event before they are allowed to perform.

h. Item 9, Sponsorship. Self-explanatory.

1. Item 10, Permanent Mailing Address of Sponsor. Self-explanatory.

J. Item 11, Policing. Furnish a detailed explanation of how crowd control will be handled.

k. Item 12, Emergency Facilities.
