A processing system for a flight simulator includes a ScramNet interface, a non-transitory memory, and a processor. The ScramNet interface is configured to establish a ScramNet bus on which ScramNet messages are transmitted and received. The non-transitory memory is configured to store computer-executable instructions for a host process and a ScramNet-to-Ethernet application programming interface (API). The processor is communicatively coupled to the ScramNet interface and the non-transitory memory, and is configured to execute the host process and the ScramNet-to-Ethernet API to: convert, using the ScramNet-to-Ethernet API, a flight control message to a first ScramNet message on the ScramNet bus, process, using the host process, the first ScramNet message to generate a second ScramNet message on the ScramNet bus, and convert, using the ScramNet-to-Ethernet API, the second ScramNet message to a display message.
