Aircraft weight reduction has always been one of the primary goal for the aviation industry as it is required to improve the fuel efficiency and meeting the strict emission goals. Considering the growing number of air passengers, the fuel needs are going to be massive in the future and the need for cutting down the emissions would call for more scrutinization. While the biggest weight reduction comes from using the composite materials and optimizing the engine designs, there are several other avenues continued to be explored, even the small savings matter. Every 1000lbs reduction from the aircraft weight saves about 1% of fuel. Creating lighter weight electrical wiring and cables is another technique and has become a trend in the industry. The techniques used for managing the audio devices by the computers have seen many advancements and it's in a matured state now, by leveraging and adapting this expertise, the aircraft industry can now move away from using the old way of transmitting data inside the aircraft. While going wireless has most probability in the future, getting rid of wires for the non-core avionics systems is a necessary now. This paper proposes one such solution for the Inflight Entertainment systems. The proposed approach can reduce the hardware components, the wirings and cables by transmitting audio over existing aircraft network, this has multifold effect as it can get rid of the audio cables used between each and every seat on the aircraft.
