Cyrrus recently completed the specification of a new Non-Directional Beacon on behalf of Norwich Airport Limited, and provided oversight to delivery of the equipment into operational service. Working with local staff, Cyrrus defined the operational requirement and generated technical and process requirements to ensure the procurement of fit-for-purpose equipment. To allow entry into service, Cyrrus completed the safety assurance process with Airport staff, producing an approved four-part safety case in-line with the Airport Safety Management System. This project continues a relationship between Norwich Airport Limited and Cyrrus that stretches over a number of years and has seen the introduction of major Communications, Navigation and Surveillance infrastructure.
