is a primary reference document published by the International Civil Aviation Organization (ICAO) that details operational procedures for flight crews and flight operations personnel. Core Purpose
对于中国及各成员国而言，各地的进近图在设计时会严格遵循PANS-OPS准则。根据Doc 8168 Volume III和相关设计规范，进近程序分为、 类精密进近（APV） 和 非精密进近（NPA） 三大类。该部分为飞行员在执行这些程序时提供了标准化的操作指引，并明确了各航段的超障标准。
While Volume I and Volume II are often the domain of procedure designers and specialists, is the "pilot’s volume." It contains criteria and instructions related to the operation of aircraft, specifically focusing on how flight crews should execute standard procedures. icao doc 8168 volume 3
The volume offers guidance on mitigating risks associated with daily operations, ensuring that the flight crew acts in accordance with international safety standards. 5. Implementation and Status of Volume III
