Safety Case Activities in SHERPA Project
ABSTRACT: This paper has been issued in the framework of the SHERPA project under the Grant Agreement No 287246 with the GSA (European GNSS Agency). This document contains the main technical activities conducted by PANSA in the frame of project’s WP2000. The objectives of WP2000 are: To work towards the implementation of a LPV procedure at each of the scenarios; To develop EGNOS National Implementation Plans, To develop and EGNOS Regional Implementation Plan, To summarise EGNOS expected benefits in a single airport. Specifically, the objectives of this document are technical activities conducted towards the implementation of a LPV procedure in scenario: procedure design, safety assessment, business case, EGNOS service provision requirements. The first step shall be to describe the operational environment at the scenario including the level of ATS provided, CNS equipment, the airport ground equipment, airspace and any procedures in place. The purpose of the operational description is to define the CONOPS specific to the airport. The Final FHA of LPV approaches is based on the Operational Model of LPV approaches in the ECAC Area, which clearly defined nominal operations prior to analyse degraded cases. For each operational action (performed by either system, human operator or jointly in the successive phases of flight), relevant failure modes were identified. Each failure mode was then analysed in turn in terms of examples of causes (to check its validity), operational consequences and mitigations, hazards, rough risk comparison against ILS operations, and when pertinent, recommendations in terms of risk reducing measures to be considered. Safety Case Activities drawn up as part of the SHERPA project was accepted by GSA, EUROCONTROL. At present an algorithm of acting while designing and executing procedures constitutes final approaches according to GNSS.
