Regulators, service providers and aircraft operators should all confirm that a GBAS based operation is safe before it is introduced. This requires a systematic use of engineering and management tools to identify, analyse and mitigate hazards during all phases of the system’s life cycle. The process is defined as a given task to be performed by a combination of people, procedures, technologies (hardware and software) and data within a given environment.

It is necessary to have a common understanding among all the relevant aviation stakeholders regarding the GBAS implementation and GBAS based services being utilised in civil aviation.

It is a State responsibility to authorise the GBAS ground facility to be used for provision of GBAS based services. 

It is also a State responsibility to authorise the aircraft operators to conduct GLS procedures based on the aircraft certified and approved GBAS capability. The aircraft's on‐board GBAS equipment certification is normally documented in the aircraft flight manuals and/or flight crew operations manuals.

The following rules regarding GBAS in civil aviation should be followed:

• Any GBAS ground facility installed at and/or in the vicinity of airport shall not be used for the provision of GBAS-based services unless certified by the regulatory authority of the State.
• Any GBAS-based service/procedure shall not be put into use for civil aviation purposes unless approved by the regulatory authority of the State.
• The details of GBAS ground facility installed at and/or in the vicinity of airport including GBAS based service/procedure shall be published in AIP.
• Aircrafts shall not utilise the GBAS based service/procedure unless the avionics requirement in terms of GBAS receiver equipage, pilot training requirements etc. are being met, as prescribed by the regulatory authority of the State.
• On‐board GBAS receiver shall be certified by the State regulatory authorities.
• The GBAS service provider shall carry out system check and operational performance monitoring on a continuous basis. The reports in respect of accuracy, integrity, availability, and continuity should be prepared and shared with the regulator on a periodic basis. Any major degradation in service or breach of terms and conditions may lead to withdrawal/cancellation of certificate/approval.
• The State may develop inspection checklists for the purpose of certification of GBAS ground facility.
• The State may develop compliance checklists for the purpose of granting approval to GBAS based services/procedures.
• The State should develop the certification methodology, which may include re‐certification criteria, revocation of certificate for GBAS ground facility, stating the certification process, regulatory requirements, period of validity, terms and conditions etc.
• The State should also develop the approval and withdrawal process for GBAS based services/procedures.
