The European Union Aviation Safety Agency (EASA) required a digital system for the standardised management of internal aviation occurrences — integrated with the European ECCAIRS standard and backed by a clear implementation concept. Portamus designed the complete processes for the Internal Occurrences Reporting System (IORS), specified the ECCAIRS integration architecture, evaluated the SAP integration options, and trained internal and external consultants for system operation. Since February 2012, IORS has been live at easa.europa.eu/iors — enabling standardised exchange of occurrence data across all European aviation authorities.
