The Principle and Maintenance of ?NM7000 Sliding Antenna
With the development of society and the improvement of people's living standards,aircraft have become a crucial mode of transportation in daily life,and flight safety issues have gradually attracted widespread public attention.The Instrument Landing System(ILS),as the standard precision approach and landing equipment of the International Civil Aviation Organization,can provide precise guidance for aircraft at decision heights under complex weather conditions,guiding them safely during approach and landing.The glide slope antenna,as a crucial component of the ILS,is directly related to the safe flight of aircraft.Once the glide slope antenna malfunctions,it will inevitably affect flight safety.This article studies the working principles of the NM7000 glide slope antenna system,analyzes the causes of antenna failures,summarizes case studies,and provides fault detection and diagnosis methods.Finally,it proposes maintenance measures for discussion and reference by peers.
