Description
The Unpack net_ctrl Packet from FlightGear block unpacks
net_ctrl variable packets received from FlightGear via the
Receive net_ctrl Packet from FlightGear block, and makes them
available for the Simulink® environment.
The Aerospace Blockset™ product supports FlightGear versions starting from v2.6. If you are using a FlightGear version older than 2.6, the model displays a notification from the Simulink Upgrade Advisor. Consider using the Upgrade Advisor to upgrade your FlightGear version. For more information, see Supported FlightGear Versions.
