Unsafe Condition
The In-Flight Entertainment Network (IFEN) system's electrical power switching is incompatible with the MD-11's design for responding to smoke/fumes emergencies, and the system lacks a means to remove electrical power other than pulling circuit breakers. This could cause flightcrew confusion during emergencies, impairing their ability to identify smoke/fumes sources and maintain safe flight.
