We are currently in Washington, D.C. for the Modeling and Simulation Technologies Conference in AIAA Aviation 2016. We have three papers that present three recent research directions that we are putting our effort. Dr.Jafers from Embry-Riddle Aeronautical University presented the first one (Formal Scenario Definition Language for Aviation: Aircraft Landing Case Study) yesterday. It was about Aviation Scenario Definition Language. In this paper we not only present a domain specific language for scenario definition for modeling and simulation in aviation, but also introduce an model-based approach for meta-modeling, scenario model development. The goal is then to utilize model transformation capabilities for executable scenarios. Today I will be presenting the second paper (Flight Simulator Model Integration for Supporting Pilot-in-the-Loop Testing in Model-Based Rotorcraft Design) on model integration in flight simulators. In this paper, we introduce both a tailored model-to-text transformation for Simulink models that address the integration challenges and a simulation framework that enables early desktop model integration to mitigate integration risks. The last one (Running High Level Architecture in Real-Time for Flight Simulator Integration) will be presented tomorrow by Torsten Gerlach. In this one, we investigated the performance of CERTI for flight simulator coupling with a real-time operating system deployment.
