6、DI) or Primary Flight Displays (PFD) used in the flight deck of transport aircraft. An attachment recommends location of these symbols on the displays.A.2 GENERAL:A.2.1 EADIs or PFDs should incorporate only those symbols appropriate for the design function. It is not intended that these displays sho
7、uld use all of the named symbols.A.2.2 Symbols shall be displayed during appropriate phases of flight, e.g., “V“ speeds shall be shown during takeoff, initial climb, approach, and landing. They should be removed from the display at other times to reduce clutter.A.2.3 The total symbology content of a
8、 display shall not result in uncontrollable clutter, close proximity of unrelated data, or use of alphanumeric and other symbols that are not easily distinguished by a pilot whose eye is at the Design Eye Point. Thus, small display formats should not be designed to contain all the symbology that can
9、 be satisfactorily included in larger displays.A.2.4 Symbols shall be grouped so that pertinent information is presented clearly and unambiguously; e.g., the airspeed tape, selected airspeed symbol, and actual airspeed symbol shall be presented so that they interact properly.A.2.5 Displays shall be
10、evaluated in a dynamic environment to ensure they perform their intended function throughout the entire operating envelope, that there is proper integration between individual symbols, and do not contain human factor deficiencies.A.2.6 Recommended symbols should be used wherever possible; however, s
11、ymbols may be refined as a result of dynamic testing or developed to display new functions.A.2.7 Symbols representing the same functions on more than one display on the same flight deck should be the same shape and color. Symbols of the same size, shape, and color may be used for more than one funct
12、ion, provided the distinction between functions is obvious and there is no risk of misinterpretation.A.2.8 Symbol geometry shown in Appendix A is typical. Specific dimensions are left to the designer.PREPARED BY SAE COMMITTEE S-7,FLIGHT DECK AND HANDLING QUALITIES STANDARDS FOR TRANSPORT AIRCRAFTSAE
