In-flight Entertainment - System Safety and Regulation

System Safety and Regulation

One major obstacle in creating an In-flight entertainment system is system safety. With the sometimes miles of wiring involved, voltage leaks and arcing become a problem. To contain any possible issues, the in-flight entertainment system is typically isolated from the main systems of the aircraft. In the United States, for a product to be considered safe and reliable, it must be certified by the FAA and pass all of the applicable requirements found in the Federal Aviation Regulations. The concerning section, or title, dealing with the aviation industry and the electronic systems embedded in the aircraft, is CFR title 14 part 25. Contained inside Part 25 are rules relating to the aircraft's electronic system.

There are two major sections of the FAA"s airworthiness regulations that regulate flight entertainment systems and their safety in transport category aircraft: 14 CFR 25.1301 which approves the electronic equipment for installation and use, by assuring that the system in question is properly labeled, and that its design is appropriate to its intended function. 14 CFR 25.1309 states that the electrical equipment must not alter the safety or functionality of the aircraft upon the result of a failure. One way for the intended IFE system to meet this regulatory requirement is for it to be independent from the aircraft's main power source and processor. By separating the power supplies and data links from that of the aircraft's performance processor, in the event of a failure the system is self-sustained, and can not alter the functionality of the aircraft. Upon a showing of compliance to all of the applicable U.S. regulations the in-flight entertainment system is capable of being approved in the United States. Certain U.S. design approvals for IFE may be directly accepted in other countries, or may be capable of being validated, under existing bilateral airworthiness safety agreements.
