1.1 本规范提供了一个过程，通过该过程，可以通过系统级测试验证航空电子系统的预期功能和符合安全目标。 1.2 软件和硬件开发保证不在本规范的范围内，如果需要开发保证过程，则不应使用本规范。 1.3 本规范无意就飞机的类型、类别、类别或功能的关键性定义其自身的适用性，本规范验证的航空电子系统可应用于这些方面，因为这样做最终会使本规范的语言与外部要求和指南相冲突。飞机的适用性、预期用途和限制最终必须由设计者、安装者和认可机构确定。 1.4 该验证过程特别涉及系统功能的定义、识别和验证。根据本规范进行的过程可能无法满足所有适用的外部要求；可能需要系统开发人员、集成商或安装人员进行额外审查，以满足特定要求或飞机的指定任务，或两者兼而有之。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This specification provides a process by which the intended function and compliance with safety objectives of avionics systems may be verified by system-level testing. 1.2 Software and hardware development assurance are not in the scope of this specification and this specification should not be used if a development assurance process is required. 1.3 The specification intentionally does not attempt to define its own applicability with regard to the type, category, class of aircraft, or criticality of function to which avionics systems verified by the specification may be applied as doing so could ultimately place the language of the specification in conflict with external requirements and guidance. Aircraft applicability, intended use, and limitations must ultimately be determined by the designer, installer, and recognizing body. 1.4 This verification process specifically addresses definition, identification, and verification of system functions. Processes conducted under this specification may not satisfy all applicable external requirements; additional review on the part of the system developer, integrator, or installer may be required to meet specific requirements or the specified mission of the aircraft, or both. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
