The Instrument Landing System (ILS) protection area is the foundation for ensuring stable and smooth navigationsignals during instrument landing. In recent years, there have been frequent invasions of ILS protection areas, causing fluctuations innavigation signals and posing a significant potential threat to flight safety. The application of 5G-A in the management of ILSprotection areas is discussed, the importance of ILS protection areas and the current potential problems is analyzed. A set ofintegrated sensory protection area model will be proposed to discuss its effectiveness and practicality.
