Minimum Performance Standard for Airborne Multipurpose Electronic Displays
<p>This SAE Aerospace Standard (AS) specifies minimum performance standards for all types of electronic displays and electronic display systems that are intended for use in the flight deck by the flight crew in all 14 CFR Part 23, 25, 27, and 29 aircraft. The requirements and recommendations in this document are intended to apply to all installed electronic displays and electronic display systems including those that have a touch screen interface within the flight deck, regardless of intended function, criticality, or location within the flight deck, but may also be used for non-installed electronic displays. This document provides baseline requirements and recommendations (see 2.3 for definitions of “shall” and “should”). This document primarily addresses hardware requirements, such as electrical, mechanical, optical, and environmental. It does not address system specific functions. It does not contain an exhaustive or comprehensive list of requirements for specific systems or functions, such as TCAS, ADS-B, GPS, weather, or shared display considerations (e.g., when should alerts be inhibited on a display system that simultaneously depicts navigation data integrated with terrain data or traffic alerting). This document is intended to be used in combination with other guidance material contained in current system specific, TSOs, Advisory Circulars (ACs), and other Federal Aviation Administration (FAA)-approved guidance material.</p><p>The requirements and recommendations in this document are intended to apply to, but are not limited to, the following types of display functions:</p><p>- Primary flight and primary navigation which include vertical situation, horizontal situation, and moving map displays.</p><p>- 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.</p><p>- Control displays including communication, navigation, and system control displays.</p><p>- Information displays which may include navigation displays used for situation awareness only, supplemental data displays, and maintenance displays.</p><p>Electronic displays can include one or more of the following interconnected components. Other configurations are possible.</p><p>- 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).</p><p>- Control Panel (CP) is an optional component providing the means for manually selecting display symbology options/modes, selections, settings, brightness, etc.</p><p>- Touch Screen (TS) is an optional component providing the means for manually selecting display symbology options/modes, selections, settings, brightness, etc.</p><p>Display Unit (DU) providing the visual display of SG symbology.</p><p>Head up displays are out of scope for this document. The minimum performance standards for head up displays are provided in AS8055A.</p>
<p>The current revision, AS8034C, now includes the minimum performance standards for touch screen enabled electronic displays. This document was developed by the SAE A-4 Electronic Display committee and supersedes AS8034, AS8034A and AS8034B.</p>
