FixedWingLib CGF for C++
  • FixedWingLib CGF (Computer Generated Forces) is a standalone real-time C++ aircraft dynamics and maneuvers library for flight training devices and simulators.

    Developers can use FixedWingLib CGF to simulate fixed-wing aircraft in their mission scenarios. FixedWingLib CGF entities can perform a large number of flight maneuvers autonomously, even complex ones such as air combat maneuvers or VTOL landing on a ship deck. FixedWingLib CGF consists of a generic (parametric) fixed-wing CGF aircraft and a virtual pilot that can perform various maneuvers.

    For a flight dynamics model tailored for pilot training purposes (such as for the ownship in a full mission trainer), please see the FixedWingLib FDM product.

    FixedWingLib CGF includes generic fighter jet, cargo, VTOL jet and UAV aircraft models. Type specific models are available from RTDynamics either at no charge or with a service contract.The flight dynamics model is a physics based 6-DOF model and maneuvers are performed by controllers. This combination allows highly realistic CGF behaviour which matches the real-world performance characteristics of the aircraft hence significantly increases the fidelity of the simulation results.

    SDK Simulation Features

    All RTDynamics models are part of a single C++ library, this allows developers to use the same SDK to integrate the products into their simulations. Models can also run in the same simulation world, for example all helicopter and aircraft models can carry EWAWS radar models, or can be targets of a EWAWS missiles.

  • The  Formation  add-on  includes  the  follow entity  controller  (FEC)  which  allows simulation  of  various  formation  related maneuvers, such as moving into formation in order and leaving the formation.

    Once activated, FEC will fly the aircraft to the desired position in formation and maintain  its position. Formation position and other parameters can be  changed  any  time.  Aircraft  will  perform the necessary corrections.

    An aircraft can leave formation and perform another maneuver at any time.


    • build CGF formations
    • move into formation in a certain order
    • leave formation
    • change formation distance and other parameters at runtime
