multiSIM developed unclassified F-35A simulation for part-task training, multi-ship multi-type training and human performance research.

The F-35A simulation is based on publicly available data and makes it possible to create realistic 5th gen fighter simulation in an unclassified environment.

A representative F-35 flight model is provided with performance and autopilot features matching the available data.

The Panoramic Cockpit Display (PCD) is simulated and the commonly used PCD portals are available. Capabilities like radar performance, radar cross section and sensor properties are simulated and can be customized and tuned by the user.

The Helmet Mounted Display System (HMDS) is also simulated and provides both the HUD when looking forward and the off-boresight symbology. FLIR and I² (NVG) images are incorporated in the HMD.

Simulator Hardware

No specific hardware is required to run the F-35 simulation. It is possible to use the simulation in a desktop setup with a simple joystick, or with multiSIM’s Reconfigurable VR Pilot Station, or even in your existing simulator (like the Bugeye cockpit in the pictures below). Cockpit simulator hardware and our simulation models can be easily integrated through the D-SIM software.

Flight Model

The multiSIM Dynamics flight model provides an approximation of the aircraft behavior. The digital flight controls are modelled to provide 1g trim, roll rate command and load factor/angle-of-attack limitting.

A detailed engine model runs in the loop to provide engine data and responses. In addition the basic autopilot modes are modelled to provide workload reduction during flight.

Possible flight conditions include (but not limited to):

  • Take-off and landings
  • Tactical Flight
  • Aerial Refueling (Boom)


Based on the publicly available data an extensive simulation of the PCD has been created. This contains simulations of the commonly used PCD portals including: AP, Engine, EFI, Fuel, HUD, TSD, T-FLIR and TWD.

A large number of data sources are simulated:

  • Active radar (AESA)
  • ESM
  • IR (DAS and EOTS)
  • Data links (Link16)
  • EOB data

This data is correlated by means of a basic algorithm to provide a fused image of the battlefield.

The sensor capabilities and the radar cross sections used by the TSD are generic, but configurable by the user.

Helmet Mounted Display System

The HMDS is simulated and provides a virtual HUD and off-boresight symbology. The video underlays are also available and it is possible to use FLIR or I² (NVG) underlays. These video underlays are generated using the physics based D-World FLIR and D-World NVG simulation.

With VR headsets the simulated HMDS provides a true representation of the HMDS being capable of looking ‘through the cockpit’. As well, it is possible to use the simulated HMDS in projection systems or display based out-the-window visuals through a simple head tracker mounted on the pilot headset or helmet.
