  • 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.
