/** Encapsulates an Aircraft and its systems.
    Owns all the parts (other classes) which make up this aircraft. This includes
    the Engines, Tanks, Propellers, Nozzles, Aerodynamic and Mass properties,
    landing gear, etc. These constituent parts may actually run as separate
    JSBSim models themselves, but the responsibility for initializing them and
    for retrieving their force and moment contributions falls to FGAircraft.
