27 Introduction LINA is a RTD project co-funded by the BMWi as part of the Luftfahrtforschungsprogramm LINA is coordinated by THALES ATM GmbH. The Euro Telematik work addresses the on-board avionics. The main goals for the avionics work are: Development of a prototype SBAS/GBAS on-board equipment to support satellite navigation based approaches up to CAT-I for General Aviation. Concept verification and validation during two flight test campaigns on a DO-128 and, finally, one on a A320. Assessment of the additional introduction of the Galileo Safety-of-Life service into the GBAS application. 27
