Special Case Analysis of Microwave Landing System During Flight Inspection
In order to ensure the accuracy and reliability of navigation information provided by microwave landing equipment in an airport after relocation and reconstruction,it undergoes service flight inspection.The special cases encountered in flight in-spection are introduced and analyzed in detail.They are checked from the equipment inspection and adjustment,position environ-ment and evaluation,multipath interference and principle analysis in turn.And the problems are finally found——airborne receiv-ing equipment unable to receive preambles due to multipath effects.A solution is proposed for raising the installation position of data antenna to increase the initial scanning angle to ensure the smooth passage of flight inspection.It fundamentally solves the problem of random jump points in airborne receiving equipment.The solution not only avoids cutting down trees in a large area,but also saves a lot of manpower,material resources and financial resources.Finally,the methods and steps of troubleshooting the problems encountered in the flight inspection of microwave landing equipment are summarized.It can provide reference for people of the same occupation.
