Minimum Performance Standard for Airborne Multipurpose Electronic Displays
Primary flight and primary navigation which include vertical situation, horizontal situation, and moving map displays.
Systems display and displays that have alerting functions which may include engine instrument, aircraft systems information/control, pilot or flight crew alerting, and documentation displays.
Control displays including communication, navigation, and system control displays.
Information displays which may include navigation displays used for situation awareness only, supplemental data displays, and maintenance displays.
Symbol Generator/Processor Unit (SG) containing display processing and symbol generation processing and symbol generation capability, power supplies, interface logic/buffer circuits and display unit interface capability. The SG receives data from external sources, produces symbols as electronic signals, and transmits the symbols to the display units(s).
Control Panel (CP) is an optional component providing the means for manually selecting display symbology options/modes, selections, settings, brightness, etc.
Touch Screen (TS) is an optional component providing the means for manually selecting display symbology options/modes, selections, settings, brightness, etc.
Display Unit (DU) providing the visual display of SG symbology.
