Systems and methods for providing or requesting avionics simulation data using API adapter

Systems and methods are disclosed for providing or requesting data for simulating avionics systems. For example, a method for providing data for simulating avionics systems may include: receiving, from a client device, a first message requesting information usable by the client device to simulate a functionality of an avionics system, the first message being in a web services data format; converting the first message to an avionics protocol data format to obtain a first converted message; providing the first converted message to a server application; receiving, from the server application, a second message including the requested information, the second message being in the avionics protocol data format; converting the second message to the web services data format to obtain a second converted message; and providing, to the client device, the second converted message.
