Broadband over power line network systems for off-board communication in aircraft and methods of operating thereof

A method for on-ground communication using an electrical power distribution system of an aircraft, the method comprising:

• communicatively coupling a first broadband over power line (BPL) communication module to the electrical power distribution system at a first location of the electrical power distribution system;
• communicatively coupling a second BPL communication module to the electrical power distribution system at a second location of the electrical power distribution system, different from the first location;
• transmitting a communication-initiation request through the electrical power distribution system from the first BPL communication module, communicatively coupled to the electrical power distribution system at the first location, to the second BPL communication module, communicatively coupled to the electrical power distribution system at the second location;
• upon receipt of the communication-initiation request at the second BPL communication module, determining received parameters of the communication-initiation request using the second BPL communication module, wherein the received parameters depend at least in part on characteristics of the electrical power distribution system between the first location and the second location while transmitting the communication-initiation request;
• comparing the received parameters to expected parameters of the electrical power distribution system between the first location and the second location using the second BPL communication module;
• and
• generating an operating indication of the electrical power distribution system between the first location and the second location while transmitting the communication-initiation request, wherein the operating indication is generated using the second BPL communication module based on comparison of the received parameters to expected parameters of the electrical power distribution system between the first location and the second location.
