该手册将人的可靠性原则和过程定义为系统安全性和可靠性的组成部分。该手册侧重于不同操作情况下的人类行为和性能，例如在控制中心，如移交到常规任务操作、常规任务操作、卫星维护或紧急操作。本手册说明了系统生命周期中人的可信性的实施，在任何项目阶段，都需要系统地考虑以下因素:作为空间系统一部分的人的因素；人的行为和性能对安全性和可信性的影响。 在这一范围内，手册的主要应用领域是支持:a.在不同项目阶段开发和验证空间系统设计；b.开发、准备和实施空间系统操作，包括其支持，如组织、规则、，培训等。收集人因失误数据，调查涉及人因失误的事件或事故。

The handbook defines the principles and processes of human dependability as integral part of system safety and dependability. The handbook focuses on human behaviour and performance during the different operation situations as for example in a control centre such as handover to routine mission operation, routine mission operation, satellite maintenance or emergency operations.This handbook illustrates the implementation of human dependability in the system life cycle, where during any project phase there exists the need to systematically include considerations of the:- Human element as part of the space system,- Impact of human behaviour and performance on safety and dependability.Within this scope, the main application areas of the handbook are to support the:a. Development and validation of space system design during the different project phases,b. Development, preparation and implementation of space system operations including their support such as the organisation, rules, training etc.c. Collection of human error data and investigation of incidents or accidents involving human error.
