本SAE航空航天标准（AS）规定了所有14 CFR第23部分、25部分、27部分和29部分飞机中飞行机组拟在飞行甲板上使用的所有类型电子显示器和电子显示系统的最低性能标准。本文件中的要求和建议旨在适用于所有已安装的电子显示器和电子显示系统，包括在飞行甲板内具有触摸屏界面的电子显示器和电子显示系统，无论其预期功能、关键性或在飞行甲板内的位置如何，但也可用于未安装的电子显示器。本文件提供了基线要求和建议（关于“应”和“应”的定义，见2.3）。本文件主要讨论硬件要求，如电气、机械、光学和环境要求。它不涉及特定于系统的功能。 它不包含针对特定系统或功能的详尽或全面的要求列表，例如TCAS、ADS-B、GPS、天气或共享显示注意事项（例如，在同时显示与地形数据或交通警报集成的导航数据的显示系统上，何时应禁止警报）。本文件旨在与当前特定系统、TSO、咨询通告（ACs）和其他联邦航空管理局（FAA）批准的指导材料中包含的其他指导材料结合使用。本文件中的要求和建议适用于但不限于以下类型的显示功能:-主要飞行和主要导航，包括垂直位置、水平位置和移动地图显示。-系统显示器和具有警报功能的显示器，可能包括发动机仪表、飞机系统信息/控制、飞行员或机组警报和文件显示。 -控制显示，包括通信、导航和系统控制显示。-信息显示，可能包括仅用于态势感知的导航显示、补充数据显示和维护显示。电子显示器可以包括以下一个或多个互连部件。其他配置也是可能的。-符号发生器/处理器单元（SG），包括显示处理和符号生成处理和符号生成能力、电源、接口逻辑/缓冲电路和显示单元接口能力。SG从外部源接收数据，生成符号作为电子信号，并将符号传输至显示单元控制面板（CP）是一个可选组件，提供手动选择显示符号选项/模式、选择、设置、亮度等的方法。触摸屏（TS）是一个可选组件，提供手动选择显示符号选项/模式、选择、设置、亮度等的方法。 显示单元（DU）提供SG符号的视觉显示。平视显示超出了本文档的范围。AS8055A中提供了平视显示器的最低性能标准。

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.The requirements and recommendations in this document are intended to apply to, but are not limited to, the following types of display functions:- 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.Electronic displays can include one or more of the following interconnected components. Other configurations are possible.- 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.Head up displays are out of scope for this document. The minimum performance standards for head up displays are provided in AS8055A.
