White Paper: Applying Wireless LAN to Airborne Critical Systems

Software for airborne application is highly safety critical as any failures may result in loss of human life. Government agencies like FAA in US enforce stringent software development practices to ensure the safety of life. The aviation community as a whole and the FAA endorse the guidelines for Airborne Applications. Sensors plugged to the Aircraft pushes the sensed data like the temperature, altitude, fuel status, engine status etc over cables which are usually laid throughout the Aircraft. This paper attempts to replace the wired communication that happens between the Modular Avionics Unit and the sensors plugged to the Aircraft.

An airborne wireless network would bring many enhanced capabilities to the aircraft, improve the safety of the aircraft and reduce the cost and weight of the aircraft. The enhanced capabilities could be gained by replacement of wires and providing the same functionalities wirelessly. The issue of aircraft wiring safety has received widespread attention in recent years highlighted by the unfortunate TWA 800 and Swissair 111 tragedies. Safety can be improved on by utilization of a wireless connection to replace wiring. Moreover, the wires used inside of aircraft take valuable space and add to the weight of the aircraft. To put this in to perspective, a large transport commercial aircraft uses 140 miles of wire weighting about 3500 pounds. A WLAN employed inside an aircraft can reduce the wiring required in an aircraft, reducing the total weight and increasing the real estate. Lastly, wires used for equipment that is carried or worn by the Aircraft decrease mobility. A WLAN would be used to replace the data buses which carry sensitive information throughout the Aircraft.
