EGNOS performance assessmentObjectives:a) Validate EGNOS performance vs MRD for aviationb) Support to the certification processEDCNEGNOS Data Collection Network

Eurocontrol EGNOS performance assessment IIPEGASUS. The reference tool for SBAS and GBAS performanceassessment (used in ASQF and PACF)PEGASUS was designed to facilitate the output data handling and interchange. Thetool provides several functionalities such as computation of position and GNSSsystems attributes like accuracy, reliability, and availability simulating MOPScompliantreceivers, computation of trajectory errors, prediction of accuracyand availability.

Safety Key Area Regulatory Process for EGNOS• Single European Sky framework• EGNOS Signal-In-Space Safety Case Part A: Design, Development and Deployment• ICAO SARPS Conformance Part B: Maintenance and Operation• EGNOS Service Provider Certification

Safety Key Area: APV Generic Safety Case• Objective:• To complete the Generic Safety Cases for two RNAV Approach TypesAPV/Baro and APV/SBAS• For each approach:• Operational Concept• FHA• PSSA• Generic Safety Case• Completion planned by July 2009• Endorsement from ECAC National Supervisory Authorities• Local Safety Case (ANSPs) Approval from National Authority

Objectives:Benefits Key Area:APV Benefits Assessment• Analyse the benefits of the implementation of RNAVapproach capability in Europe• In particular, we will:• Estimate the potential reduction in current operationalminima at case study airports• Evaluate the potential increase in airport operationalcapacity• Estimate the corresponding cost savings from the resultingreduction in number of aircraft missed approaches• Assess the European-wide implementation costs to bothANSP/airports & airspace users

Cost/Benefit Key AreaBusiness Model and Cost Benefit Analysis• Generic Business model• Specific Business models (ANSPs, Airlines,…)• GIANT Project: Business case for SBAS Equipage focused on AirNostrum – major Regional Airline Positive and promising results• EUROCONTROL RNAV Approach Business Case
