FlightGear Preconfigured 6DoF Animation

Connect model to FlightGear flight simulator

  • Library:
  • Aerospace Blockset / Animation / Flight Simulator Interfaces


The FlightGear Preconfigured 6DoF Animation block lets you drive position and attitude values to a FlightGear flight simulator vehicle given double-precision values for longitude (l), latitude (μ), altitude (h), roll (ϕ), pitch (θ), and yaw (ψ), respectively.

The block is configured as a sim viewing device. If you generate code for your model using Simulink® Coder™ and connect to the running target code using external mode simulation, Simulink software can obtain the data from the target on the fly and transmit position and attitude data to FlightGear. For more information, see Use C/C++ S-Functions as Sim Viewing Devices in External Mode (Simulink).

Longitude, latitude, altitude, roll, pitch, and yaw, in double-precision, specified as a vector. Units are degrees west/north for longitude and latitude, meters above mean sea level for altitude, and radians for attitude values.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated | bus

Select your FlightGear software version from the list.


If you are using a FlightGear version older than 2.0, the model displays a notification from the Simulink Upgrade Advisor. Consider upgrading your FlightGear version using the Upgrade Advisor. For more information, see Supported FlightGear Versions.

The block is a masked subsystem containing principally a Pack net_fdm Packet for FlightGear block set for 6DoF inputs, a Send net_fdm Packet to FlightGear block, and a Simulation Pace block. To access the full capabilities of these blocks, use the individual corresponding blocks from the Aerospace Blockset™ library.
