    • Abstract:
      A kinematics-based flight model, for normal flight

      regimes, currently uses precise flight data to achieve a high

      level of aircraft realism. However, it was desired to further

      increase the model’s accuracy, without a substantial increase in

      program complexity, by determining the vertical velocity and

      vertical acceleration using EUROCONTROL’s Base of Aircraft

      DAta (BADA) model [1]. BADA is a well-known aircraft

      performance database model maintained and developed by

      EUROCONTROL Experimental Centre in France.

      The hybrid model uses the BADA algorithm to determine the

      vertical velocity and gives original results for determining the

      vertical acceleration. The approximate accuracy of these

      vertical parameters was checked by comparing them with preexisting

      test distributions [2] and an in-house flight simulator

      application. The hybrid model uses kinematic algorithms for all

      other functions and parameters. To obtain specific results, C

      code was written to access text data from BADA’s collection of

      approximately one hundred airplanes. Accessing this database

      causes an increase in overall program execution time that was

      deemed acceptable due to the infrequency of changing plane

      types. Also, by examining many airplane trajectories obtained

      from different BADA airplanes, we determined that the model is

      accurate enough to uniquely represent many different types of

      aircraft.
