Wireless local area network (WLAN) technology is widely used for wireless access services between the user and user terminal in the office, school and family local area network. In recent years, foreign airlines began to set up wireless local area network on aircraft for passenger services. Passenger can obtain information, communication with ground and entertainment services through the wireless local area network on aircraft. In order to ensure the safe operation of the aircraft and the safety and steady operation of wireless local area network on aircraft, an aircraft electromagnetic compatibility test with wireless local area network is therefore required. The major study of this paper focuses on the composition of the wireless local area network on aircraft and aircraft electromagnetic compatibility test requirements and test procedures. Detailed analyses the aircraft electromagnetic compatibility test methods and procedures with wireless local area network prior the installation of wireless local area network.
