In the following subsections, there are provided guidelines about the phases needed for the implementation of GBAS.
Identify the operational requirements and performance gaps that justify implementing a GBAS solution.
Evaluate the financial feasibility, comparing implementation costs with operational and safety benefits.
Assess the site conditions, GNSS signal quality, and technical capabilities required for GBAS deployment.
Apply for the VHF Data Broadcast (VDB) frequency allocation for GBAS operations.
Develop the Concept of Operations detailing how GBAS will integrate into airport and airspace operations.
Select the GBAS manufacturer and configuration that best meet performance, interoperability, and safety needs.
Install the GBAS ground station, antennas, and communication infrastructure according to design specifications.
Update obstacle limitation surfaces and height restrictions to ensure compliance with GBAS flight path design.
Define procedures for air traffic control, maintenance, and operational continuity in case of GBAS outages.
Design precision approach procedures supported by GBAS for qualifying runways, ensuring ICAO compliance.
Conduct calibration and validation flights to verify GBAS signal integrity and procedure accuracy.
Establish spare parts management, maintenance contracts, and support channels for system sustainability.
Provide training for air traffic controllers, maintenance staff, and flight crews on GBAS operations.
Draft national or regional regulations and guidance material for GBAS approval and continued operation.
Obtain certification from the relevant aviation authority for the GBAS installation and its procedures.
Perform a detailed safety assessment to ensure GBAS operations meet target safety levels and risk criteria.
Publish the approved GBAS procedures, frequencies, and operational details in the Aeronautical Information Publication.
Evaluate GBAS performance after operational launch, incorporating lessons learned for continuous improvement.
