- This specification governs the definition of requirements for, and methods of, presenting characteristics and performance data for U.S. military piloted aircraft.

- For all piloted aircraft proposed or contracted for subsequent to the effective date of this specification, characteristics and performance data shall be prepared and presented in accordance with the provisions of this specification and submitted to the procuring agency for acceptance, unless specifically exempted or otherwise authorized by the procuring agency. Deviations from the provisions of this specification to portray more adequately the capability of certain aircraft are permissible, but shall in all cases be approved by the procuring agency. Authorized deviations shall be fully explained through proper annotations on the data charts.

- Characteristics and performance data shall be presented on the following types of charts as required by the procuring agency and utilizing formats as provided. Unauthorized reproduction of such charts is prohibited.

- The Standard Aircraft Characteristics chart for the presentation of detailed data is essentially self-explanatory, and is composed basically of six pages. The page sizes, when reproduced, shall be as specified by the procuring agency. The pages shall be arranged as follows:

(a) First page - cover sheet which shall include a photograph, or perspective drawing of the aircraft model.

(b) Second page - a drawing showing a descriptive arrangement of the aircraft, and a drawing showing the tankage installations, armament installations, cargo space, or interior arrangements, as required by the procuring agency.

(c) Third page - mission, description, and principal characteristics of the aircraft.

(d) Fourth page - performance data for the aircraft in tabulated form and applicable notes.

(e) Fifth page - performance graphs.

(f) Sixth page - description of mission problems; also continuation of notes and diagrams.

- Aircraft characteristics and performance data not coming within the scope of the Standard Aircraft Characteristics charts shall be presented on Supplemental charts. Reasons for preparing Supplemental charts may be as follows:

(a) Possible special loadings or extreme overloading conditions which may:

(1) Be used in restricted tactical operations

(2) Involve nonstandard procedure and special operating techniques, except as provided herein (see paragraphs and

(3) show the maximum potential use of certain aircraft in special missions.

(b) Such loadings that may involve equipment which for security reasons are only suitable for limited distribution.

(c) Theater operations involving nonstandard atmospheric conditions.

(d) To show inboard profiles, additional drawings, illustrations, and graphs.

(e) To show carrier suitability characteristics of carrier-based aircraft.

The Supplemental chart format may be the same as the Standard Aircraft Characteristics, or may consist of a single sheet of special design suitable for binding along with the corresponding basic Standard Aircraft Characteristics chart.

- The Characteristics Summary chart is intended to present a summary of performance capabilities on the basic mission and principal features in an abbreviated form. Data shown on the Characteristics Summary chart shall be in agreement with similar data shown on the Standard Aircraft Characteristics charts. The standard format for the Characteristics Summary for each aircraft model, shall consist basically of a two-page, single sheet, and shall be 8 by 10-½ inches in size after reproduction.

- The above charts shall be identified by categories to show the development status of the aircraft or data involved. All chart formats shall be completed in full detail.

- Proposal data charts are intended to provide information during the evaluation of new aircraft designs, design studies, and proposed modifications of existing aircraft and are suitable primarily for limited distribution within the procuring agency.

- Pre-mock-up data charts are intended to provide information on new aircraft designs during the interim period from initial procurement to completion of mock-up. The initial pre-mock-up data charts need not include the effect of all design changes recommended by the procuring agency but a list of major design changes shall be given under the notes on the chart.

- Experimental data charts are intended to provide information on experimental aircraft models. The initial issue of a chart on an experimental aircraft model shall normally be prepared when the configuration and weight for an experimental aircraft design have stabilized following the mock-up inspection.

- Service Test data charts are intended to provide information on production aircraft models assigned on limited quantities for service evaluation. Charts shall be prepared as soon as practicable after such assignment.

- Service data charts are intended to provide information on service aircraft models. Preparation of the initial issue of a chart on a service aircraft model shall normally be initiated not later than when the configuration and weight have stabilized following the mock-up inspection.

- Each page of the foregoing chart types shall be marked as follows:

(a) The military model designation or the contractor's model designation (in the case of charts in the proposal category) shall be shown on the lower outer corner.

(b) The chart category as defined in paragraph 1.4 shall be shown on the upper outer corner.

(c) The date shall be shown on the lower-inner corner.

(d) The security classification shall be as specified by the procuring agency and shall be shown on center at top and bottom.

(e) The upper-inner corner is reserved for use by the procuring agency.
