6、ays (ED) used on the flight deck of turbofan power transport aircraft.C.2 GENERAL:C.2.1 EDs should incorporate only that symbology appropriate for the installed engine.C.2.2 EDs should at all times be appropriate to the phase of flight, the type of operation (normal versus non-normal) and the automa
7、tic monitoring capability of the aircraft relative to engine parameters.The goal should be to limit displays at a given time to those required by the pilot to control the aircraft, to observe operating limits and to analyze the current status of the engines. For example, for aircraft with extensive
8、automatic monitoring and alerting capability, it may be desirable to provide the pilot with continuous display of the thrust parameter only; all other engine parameters would be available on an exception basis; i.e., automatically called up for a particular phase of flight or a malfunction/exceedanc
9、e or manually called up by the pilot.C.2.3 Displays may vary in size and shape. The total symbology content of a display should not result in clutter. Thus, small display formats should not be designed to contain all the symbology that can be satisfactorily included in larger displays.C.2.4 Symbols
10、should be grouped so that pertinent information is presented clearly and unambiguously; for example, actual, reference and redline value symbols should be presented so that they interact properly.C.2.5 Each engine should be readily identifiable and its parameters easily compared with those of other
11、engines.C.2.6 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 displays and that displays do not contain human factor deficiencies.C.2.7 Recomm
12、endations for display element features should be observed whenever possible; however, symbols may be refined or tailored to specific installations as a result of dynamic testing.:C.3 ENGINE DISPLAY SYMBOLOGY:C.3.1 The matrix on the following page shows, for each engine parameter, the “elements“ that
13、 should be included in that parameters display. Note that the last two columns are “continuous“ and “conditional“. Except for the primary thrust parameter, which should be “continuous“, the recommendation for continuous or conditional depends on the automatic monitoring and pilot alerting capability
14、 of the aircraft systems.SAE ARP4102-7- 50 -C.3.2 The charts following the Display Requirements matrix show examples of typical existing configurations of each display element along with verbal recommendations for the “ideal“ configuration.Pages 51 to 67 show examples of typical existing symbology f
