The goal for Hati Flight 1 was to conduct the first flight test on this center-body and the first flight test with Wing Set 3. The objective was to conduct open-loop chirps at 23 m/s and 26 m/s to analyze the rigid and flexible body dynamics of the vehicle and wing set. A secondary goal was to validate the aircraft systems and instrumentation, now with a sample rate of 150 Hz and a reduced total delay of 20 ms. Shortly after takeoff and climb out, the aircraft was switched into autopilot mode where pilot pitch and roll stick maps to pitch angle and roll angle commands. It was noticed that the pitch and roll angle command tracking was not responding well, the test points were discontinued, and the aircraft returned for a successful landing. Included is the aircraft flight data, the flight cards, and a summary of the Euler angle fault as well as planned corrections.
