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.
