Aspects relate to method and systems for simulated intra-aircraft communication using a physical network. An exemplary method includes receiving simulator data from an aircraft simulator, disaggregating a simulated digital message from the simulator data, abstracting a simulated signal as a function of the simulated digital message, transmitting the simulated signal on a physical network, receiving, using at least an aircraft component communicative with the physical network, the simulated signal by way of the physical network, transmitting a phenomenal signal by way of the physical network, receiving the phenomenal signal by way of the physical network, converting a phenomenal digital message as a function of the phenomenal signal, and inputting the phenomenal digital message to the aircraft simulator.
