本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本标准描述了在设备终端向机载设备提供电力的特性，以及机载设备使用此类电力的要求。本标准的目的是促进飞机电气系统或地面支持电气系统与机载使用设备之间的兼容性，以将飞机和地面支持电力特性限制在确定的范围内，并限制机载使用设备对电力的要求。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.The standard delineates the characteristics of electric power supplied to airborne equipment at the equipment terminals and the requirements for the utilization of such electric power by the airborne equipment. The purpose of this standard is to foster compatibility between aircraft electric systems or ground support electric systems and airborne utilization equipment to the extent of confining the aircraft and ground support electric power characteristics within definitive limits and restricting the requirements imposed on the power by the airborne utilization equipment.
