Take your model-based development and testing to the next level with iAircraft

iAircraft is an aircraft simulation modeling package designed specifically for use in aircraft lab test facilities such as “iron bird” simulators and simulation-based avionics integration test facilities. iAircraft has been developed for the simulation of commercial aircraft and can also be parameterized to represent a wide range of fixed-wing aircraft. iAircraft is made up of a collection of Simulink models that may be run within the Simulink simulation software or on ADEPT-based real-time simulation computer systems (rtX, rtX-V). iAircraft has been developed with an architecture that allows the aircraft simulation to get up and running quickly in pure simulation mode, but also makes it easy to connect real aircraft LRU for performing aircraft hardware-in-the-loop testing, integration, and avionics verification activities. The iAircraft simulation modeling methodology is based on commercial aircraft industry-leading research and development for several decades.

iAircraft Packages

iAircraft Lite DT

iAircraft Lite DT provides an entry-level point for aircraft flight simulation on the Desktop. iAircraft Lite supports aircraft take-off and landing dynamics.  iAircraft Lite does NOT include the level of detail required to connect real aircraft electronic systems.  The suggested uses of iAircraft Lite are:

  • to provide an aircraft simulation model early in an aircraft development program to enable the user to begin performing real-time flight simulation
  • University teaching tool for introducing to students:
    • flight simulation
    • control system development
    • hardware-in-the-loop simulation
    • systems integration


  1. environment conditions
  2. aircraft dynamics
  3. aircraft aerodynamics
  4. aircraft autopilots and control
  5. landing gear
  6. engine

Each of these modules could be replaced with a user-defined element.

Does not support the addition of iAircraft+ modules.  Requires Simulink 2011b or later.

iAircraft Lite RT

iAircraft Lite RT provides the capabilities of iAircraft Lite running on an ADEPT based real-time simulation computer. Does not support the addition of iAircraft+ modules. Requires Simulink 2012b or later. Requires ADEPT Framework.

iAircraft Standard DT

iAircraft Standard DT provides a desktop simulation library that includes the level of detail required in simulation-based aircraft test facilities. iAircraft includes appropriate interface points for connecting the model with real and simulated electronic control systems. iAircraft does NOT include as high-fidelity on-aircraft subsystems (engines, electrical systems, etc) but it can be integrated with iAircraft high-fidelity aircraft subsystem modules (i.e. iAircraft+) and with customer furnished simulation subsystems. iAircraft includes trim routines required to initialize the aircraft flight simulation to a stable, know condition (speed, altitude, heading, etc).

Requires Simulink 20011b or later.

iAircraft Standard RT

iAircraft Standard RT provides the capabilities of iAircraft Standard running on an ADEPT-based real-time simulation computer. Requires Simulink 2012b or later. Requires ADEPT Framework.
