7、raft. C.2GENERAL: C.2.1EDs should incorporate only that symbology appropriate for the installed engine. C.2.2EDs should at all times be appropriate to the phase of flight, the type of operation (normal versus non-normal) and the automatic monitoring capability of the aircraft relative to engine para
8、meters. 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 automatic monitoring and alerting capability, it may be desirabl
9、e 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/exceedance or manually called up by the pilot. C.2.3Displays may vary in
10、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.2.4Symbols should be grouped so that pertinent information is presented cle
11、arly and unambiguously; for example, actual, reference and redline value symbols should be presented so that they interact properly. C.2.5Each engine should be readily identifiable and its parameters easily compared with those of other engines. C.2.6Displays shall be evaluated in a dynamic environme
12、nt 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.2.7Recommendations for display element features should be observed whenev
13、er possible; however, symbols may be refined or tailored to specific installations as a result of dynamic testing.: C.3ENGINE DISPLAY SYMBOLOGY: C.3.1The matrix on the following page shows, for each engine parameter, the “elements“ that should be included in that parameters display. Note that the la
14、st 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 of the aircraft systems.
