On the 12th of September 2019, Open Day Flight Trials, part of the project GRADE plan took place at the German Airspace Center (DLR), situated in Braunschweig, Germany.
The project GRADE is a Pan-European project, which aims to demonstrate the possibilities of integrating general aviation aircraft and rotorcraft into airspace and airports, using SESAR concept solutions.
The flight trials aim to show the applicability of SESAR Solutions #51, #55, #103 and #113 for general aviation aircraft and rotorcraft. These comprise simultaneous flights of a small Cessna aircraft and an EC135 helicopter on different routes with conflicting trajectories, infringing minimum separation. The aircraft are equipped with technological equipment, designed by DLR and Technische Universität Braunschweig (TUBS), which allows for the successful safe execution of such flights. Two different interfaces were presented, as well as recordings of the flights, carried out previously. The flight trials were successfully executed in the afternoon, under favourable weather conditions.
According to GRADE project plan, flight trials will also take place in the Italian Aerospace Research Centre (CIRA) in Capua, Italy in October 2019.
