    Descripció del contingut i pla d'activitats:
    The aim of this project is to improve the performance model of the QPAC
    (QualityPark AviationCenter) A320 in X-Plane flight simulator. In order to
    achieve it, tables generated with Airbus PEP (Performance Engineering
    Program tool) have been used. The process followed consists in using PEP
    tables as look-up tables for the simulator, so that via a plugin it is possible to
    move this data from PEP to X-Plane. It is of great interest to have a correct
    performance model in the simulator, as it will lead to more accurate results
    when testing new aeronautical concepts with flight simulations. In this project
    it will be shown as an example how the improvement of the model allows to
    obtain better results in a CDO (Continuous Descent Operations) simulation
    with X-Plane. The performance model in X-Plane is based in blade element
    theory, which is one of the big differences with the other flight simulators
    available nowadays. Although the results are quite good in most of the
    aspects of the simulation, there are great inaccuracies when it comes to
    model transonic and supersonic effects. In addition, thrust values are not very
    good neither. The performance corrections have been applied on drag and
    idle thrust. PEP tables have been moved to header files in C++ so that an X-
    Plane plugin can read them easily. In the drag case, drag coefficients are read
    given Mach number and lift coefficient as input values while in the idle trust
    case, idle thrust values are read given Mach number and altitude as input
    values. After applying the corrections, it has been observed a big
    improvement in both drag and idle thrust values, with low errors when
    comparing with PEP data. However, there are still some inaccuracies in the
    model, so some future work will be needed.
