本航空航天推荐规程的目的是通过制定设计标准，在正常和紧急情况下提供最佳使用，从而为所有运输飞机的飞行甲板内门及其操作提供标准化建议。飞行甲板内门是将飞行甲板区域与任何客舱区域或通向任何客舱区域（无论是乘客还是货物）的区域连接起来的门，不包括从飞行甲板直接通向飞机外部的任何门。

The purpose of this Aerospace Recommended Practice is to provide recommendations which will lead to the standardization of flight deck interior doors and their operation in all transport aircraft by establishing design criteria which will provide optimum use under normal and emergency conditions. The flight deck interior door is that door which connects the flight deck area with any cabin area or area leading to any cabin area, whether passenger or cargo, and does not include any door leading from the flight deck directly to the outside of the aircraft.
