Abstract:
Since 2004, there occurred lightning accidents many times to airport facilities at Mianyang Airport，such as the Doppler VHF Omnidirectional Radio/Distance Measurement Equipment, Instrument Landing System, No Directional Beacon, Transportable Earth Stations, Aviation Automated Weather Observing Systems, Very High Frequency radio and so on, which caused equipment failure and work interruptions in different degrees. Through analyzing the lightning cases, some countermeasures are introduced, such as multi level SPD protection, eliminating lightning residual voltage step by step, integrated grounding and equipotential bonding for all the equipments within the same building, standardizing the generic cabling and establishing the regular maintenance and detection system, checking potential safety hazard timely, etc. Some experiences and effective means to clear up faults in communication and navigation facilities induced by lightning accidents are summarized.
