Study on Advanced Approach and Landing Operations Utilizing GBAS

The Ground-Based Augmentation System (GBAS) supports safe approach and landing, even under weather conditions with low visibility. As well as additional information to enhance the reliability of GNSS satellite signals, its ground facility also broadcasts data blocks on approach paths. When the GBAS is compared with a conventional instrument landing system (ILS), prominent GBAS advantages include not only scope to support precision approaches with multiple approach paths but also eliminating the need for protection areas of ILS radio waves on runways, which might improve runway throughput. Leveraging these advantages could allow a more exible approach and landing operations and reduce environmental loads. Expected bene ts include reduced fuel consumption and noise and enhanced capacity of congested airports.
