本SAE航空航天标准(AS)规定了所有14 CFR第23、25、27和29部分飞机中的机组人员在飞行甲板上使用的所有类型的电子显示器和电子显示系统的最低性能标准。本文档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，包括那些在驾驶舱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、关键程度或在驾驶舱内的位置如何，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（请参阅 2.3 关于“应当”和“应当”的定义）。本文档主要讨论硬件要求，如电气、机械、光学和环境。它不涉及系统特定的功能。它不包含特定系统或功能的详尽或全面的要求列表，如TCAS、ADS-B、GPS、天气或共享显示考虑因素（例如，何时应该在同时描绘与地形数据或交通警报集成的导航数据的显示系统上禁止警报）。本文件旨在与当前系统规范、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。 本文档中的要求和建议旨在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，包括垂直情况、水平情况和移动地图显示。系统显示器和具有警报功能的显示器，其可以包括发动机仪表、飞机系统信息/控制、飞行员或机组人员警报以及文档显示器。 控制显示器，包括通信、导航和系统控制显示器。 信息显示器，其可以包括仅用于态势感知的导航显示器、补充数据显示器和维护显示器。 电子显示器可以包括以下互连部件中的一个或多个。其它配置也是可能的。 符号生成器/处理器单元(SG)，其包含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，产生符号作为电子信号，并将符号传输到显示单元。控制面板（CP）是一个可选组件，提供用于手动选择显示符号系统选项/模式、选择、设置、亮度等的装置。 触摸屏(TS)是提供手动选择显示符号系统选项/模式、选择、设置、亮度等的装置的可选组件。 提供SG符号的视觉显示的显示单元(DU)。 平视显示器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。 注:本文件预计将被FAA用作多用途电子显示器技术标准令（TSO）的基本要求。虽然不是必需的，ARP1874和ARP4067给出了基于CRT的显示器符合本标准的推荐方法，但不是唯一的方法。此外，ARP4256虽然不是必需的，但给出了第25部分LCD显示器符合本标准的推荐方法，但不是唯一的方法。该文件可能会根据经验和技术进步进行更改。目前不存在用于第23部分飞机的类似文件，但是这些文件可以用作打算安装在第23部分、第27部分和第29部分飞机中的电子显示器的基础，认识到附加要求也可能适用。

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. NOTE: This document is expected to be used by the FAA as the basic requirement for a Technical Standard Order (TSO) for multipurpose electronic displays. While not required, ARP1874 and ARP4067 give recommended means, but not the only means, of compliance to this standard for CRT based displays. In addition, while not required, ARP4256 gives recommended means, but not the only means, of compliance to this standard for Part 25 LCD displays. That document is subject to change to keep pace with experience and technical advances. A similar document for Part 23 aircraft does not exist at this time, however these documents may be used as the basis for electronic displays intended to be installed in Part 23, 27, and 29 aircraft, realizing that additional requirements may also apply.
