本文件中提供的热建模指南和最佳实践适用于-65至+260摄氏度（-85至+500华氏度）热环境和海平面至空间真空压力范围内的动力航空航天飞行器电线和线束。目前，ARP只考虑稳态和直流条件。布线终端和连接器的影响未得到解决。两者都会显著影响布线系统的整体电流降额和安全裕度。

The thermal modeling guidelines and best practices provided in this document are applicable to powered aerospace vehicle wires and wire bundles in thermal environments ranging from -65 to +260 ¿¿C (-85 to +500 ¿¿F) and pressures ranging from sea level to space vacuum. Currently the ARP only considers steady state and direct current conditions. The effects of wiring terminations and connectors are not addressed. Both can significantly impact the overall current derating and safety margins for a wiring system.
