The introduction of GBAS in any State represents a significant change for aviation, so it requires new approaches to regulation, provision of services and operation of aircraft, and personnel training is the key for the success of implementation.
A Training Needs Analysis should be completed by States to identify the training needs for all stakeholders involved in the operation, use and maintenance of the GBAS. Stakeholders that should be included within the analysis encompass ATC staff, maintenance staff, engineering staff, pilots, and procedures designers.

The Training Needs analysis should:

• Identify the impact of GBAS implementation to the stakeholder and a determination of any training required
• Include an analysis of the skills and knowledge required to install, certify, operate and/or maintain the GBAS ground facility and GBAS based services
• Consider training resources, methods and delivery requirements

The training might involve different users:

• General Awareness training: General awareness involve training on the overview of GNSS and Augmentation systems, principles of operation of a GBAS, differences between an ILS and GBAS based precision approach and the limitations and advantages of a GBAS, and should be provided to all stakeholders.
• ATC: ATC staff should be provided with a briefing on the GBAS, changes to local instructions as a result of the introduction of a GBAS, changes to the information contained within a Flight Plan, interpretation of GBAS monitoring indications, and training on any new systems introduced to support delivery of a GLS approach capability.
• Regulators: Regulators should be provided with general awareness training and the training belonging to applicable SARPs for updating the regulation to include GBAS operations.
• Maintenance: Staff responsible for maintaining the GBAS should be provided with training on the fundamental principles of operation of a GBAS, specific equipment, operation of the equipment and maintenance practices for the equipment including routine maintenance activities to be performed and procedures for investigating of faults and failures. States may elect to develop a set of GBAS competency criteria against which the competency of maintenance staff would be assessed.
• Engineering: Staff responsible for Engineering Management of the GBAS ground facility should be provided with training on advances GBAS concepts, configuration management of the GBAS, fault detection, and complex fault analysis.
• Pilot: Pilot training will be driven by the airline and specific aircraft type. Pilot training may involve a differences course between GBAS and ILS and corresponding simulator training.
• Procedures Design: Instrument Flight Procedures Designers may be provided with supplementary training on the differences between GBAS and ILS and information contained within a Final Approach Segment (FAS) data block.
• AIS: AIS personnel should be provided with training on the specificities of GBAS aeronautical information, including GBAS NOTAMs.
