固定或永久位置飞行甲板平视显示器

[中文适用范围]： 本航空器标准建议实践（ARP）规定了运输类飞机抬头显示器（HUD）系统在设计与安装、操作及培训方面的准则，重点在于飞行员接口与运行要求。该建议适用于显示主要飞行信息的固定式安装（包括可收纳式）HUD，以及集成增强飞行视景系统（EFVS）图像的HUD。其目的是确保HUD的设计与使用能够提升飞行员在所有飞行阶段（包括低能见度运行）的情景意识与飞行技术性能。虽然光学性能、硬件规范等工程技术标准已在ARP 5288和AS 8055等文件中界定，但本文件侧重于飞行员使用考虑与人因工程。文中涉及的HUD系统通常旨在支持适用于三类仪表进近运行（如获批准）的失效—被动运行概念；诸多建议亦适用于一类与二类运行及其他飞行阶段的HUD使用。头戴式显示器等装置未在此专门涵盖，但随着技术发展，未来条款可能考虑“透显式”可穿戴系统。请参阅m [外文原描述]： This SAE Aerospace Recommended Practice (ARP) provides criteria for the design, installation, operation, and training aspects of head-up display (HUD) systems in transport category aircraft, with emphasis on pilot interface and operational requirements. The recommendations apply to permanently installed (including stowable) HUDs that display primary flight information, including those integrating enhanced flight vision system (EFVS) imagery. The intent is to ensure HUDs are designed and used in a manner that improves pilot situational awareness and flight technical performance across all phases of flight, up to and including low-visibility operations. While technical design standards (optical performance, hardware specs, etc.) are defined in documents like ARP5288 and AS8055, this document focuses on pilot usage considerations and human factors. HUD systems addressed here are typically designed to support a fail-passive operational concept applicable to Category III instrument approach operations, where approved, though many recommendations also apply to HUD usage for Category I and II operations and other phases of flight. Devices such as head-worn displays are not specifically covered, though future provisions may consider “through-display” wearable systems as technology matures.
