MIL-STD-704 is a United States Military Standard that defines the requirements for aircraft electric power characteristics. It was originally developed in the 1950s for use in military aircraft, but has since been adopted by many commercial aircraft manufacturers as well. The standard covers a range of topics related to aircraft electric power, including voltage levels, frequency, phase, and power quality. It defines the requirements for different types of aircraft systems, including flight control, avionics, and lighting.

MIL-STD-704 includes a series of performance requirements and test procedures to ensure that aircraft electrical systems are designed and manufactured to meet the standard. Compliance with MIL-STD-704 is typically verified through testing during the development and production of the aircraft. The standard is periodically revised to incorporate new technologies and updates to industry practices. The most recent version of MIL-STD-704 is Revision F, which was published in 2017.

Overall, MIL-STD-704 is an important standard for the aerospace industry and plays a critical role in ensuring the safety and reliability of aircraft electrical systems. By establishing clear requirements for aircraft power characteristics, the standard helps to ensure that aircraft systems are designed and manufactured to a consistent level of quality, regardless of the manufacturer.

BNS compliance with MIL-STD-704, means that BNS has been designed and manufactured to meet the electrical power requirements specified in the standard. This is an important consideration for aerospace organizations that require network security appliances for use in their aircraft, as it would indicate that the product is designed to meet the same electrical power characteristics as other aircraft systems.
