本文所含标准适用于主要安装在多引擎涡轮动力飞机（固定翼和旋转翼）上的记录设备，用于自动记录飞行数据参数和音频信息。本标准不适用于根据《联邦法规》第14篇航空航天第121部分运行的大型飞机。该航空航天标准（As）规定了自动记录飞机飞行安培表和（或）飞行机组成员之间的听觉通信、听觉警告声音和与飞行操作所必需的飞机之间的通信的最低性能标准。 本标准旨在允许使用单个驾驶舱语音记录器（CVR）或飞行数据记录器（FDR）设备，或CVR/FDR组合。

The standards contained herein apply to recording equipment intended primarily for installation in multi-engine, turbine powered aircraft (fixed and rotary wing) for automatically recording flight data parameters and audio information. This standard is not intended for large aircraft operating under Code of Federal Regulations Title 14, Aeronautics & Space, part 121. This Aerospace Standard (AS) specifies minimum performance standards for recording automatically aircraft flight par ammeters and (or) aural communication between flight crew members, aural warning sounds, and communications to and from aircraft necessary for flight operations. It is the intent of this standard to allow for the use of individual Cockpit Voice Recorder (CVR) or Flight Data Recorder (FDR) equipment, or a combination CVR/FDR.
