vsTASKER was successfully used as the backbone simulation software by CIRA (Italian Aerospace Research Centre) for a GRADE demonstration of curved satellite GNSS approach.
Under hundreds of simulation runs, about 80 GNSS approaches were completed, covering a wide range of operative conditions both nominal and off-nominal, done by pilots, controllers and human factors experts.
For these exercise, vsTASKER has been selected and used to produce the interactive air-traffic control panel intended for use by ATC expert to manage the traffic. The HMI Builder of vsTASKER including logic and mapping capabilities was used for the display.
vsTASKER was also used for managing the traffic based on flight-plans and ARINC 424 databases. Human operators were manually directing some specific aircraft according to the needs of the ATC.
Finally, vsTASKER HMI and simulation engines were part of a distributed environment including a flight simulator with a pilot in the loop.
The demonstration objectives has been achieved through in flight live trials performed at two different sites, using three different aircraft. The flight trials were complemented by preparatory Real-Time Simulation campaigns, with hardware and humans in the loop, in order to identify the most relevant scenario conditions to be tested in flight, to assess possible safety risks during the in-flight trials, as well as to achieve preliminary assessment of measurable performance indices in realistic environments.
The GRADE project has received funding from the SESAR Joint Undertaking under the European Union’s Horizon 2020 research and innovation program under grant agreement 783170.
