| Abstract(in English) | This paper describes the ElectroMagnetic Interference (EMI) in avionics systems caused by portable electronic devices (PEDs). The path loss from PEDs to aircraft navigation systems and to cables on the cabin floor were measured in Boeing 777s. Results show that the total path loss from PEDs to navigation systems is 43dB in minimum and 90dB in average, suggesting the little probability of interference to avionics ; however, there remains some probability of the interference. The path loss to the cables is large enough so as the interference through the path can be ignored. Several PEDs were used in aircraft cabin, both on the ground and in flight to investigate the interference. However, no interference to the navigation systems was observed during the test. |
