6、EHSI) or Navigation Displays (ND) used in the flight deck of transport aircraft. An attachment recommends location of these symbols on the displays.B.2 GENERAL:B.2.1 EHSIs or NDs should incorporate only those symbols appropriate for the design function. It is not intended that these displays should
7、use all of the named symbols.B.2.2 Symbols shall be displayed during appropriate phases of flight, e.g., Vertical Deviation scale should only be displayed on the Map Format during FMC computed descents. They should be removed from the display at other times to reduce clutter. For general arrangement
8、 (e.g., MAP,PLAN, COMPASS) the display should be basically stable.B.2.3 The total symbology content of a display shall not result in 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 Positi
9、on. Thus, small display formats should not be designed to contain all the symbology that can be satisfactorily included in larger displays.B.2.4 Symbols shall be grouped so that pertinent information is presented clearly and unambiguously, e.g., the heading arc, selected heading, and actual heading
10、symbols shall be presented so that they interact properly.B.2.5 Displays shall be 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 d
11、eficiencies.B.2.6 Recommended symbols shall be used wherever possible, however, symbols may be refined as a result of dynamic testing or developed to display new functions.B.2.7 Symbols representing the same functions on more than one display on the same flight deck should be the same shape and colo
12、r. Symbols of the same size, shape, and color may be used for more than one function, the distinction between functions shall be obvious, and there shall be no risk of misinterpretation.B.2.8 Pilot selection capability shall be provided for symbology which is not continuously used, e.g., bearing poi
