A system for an aircraft having a first gas turbine engine and a second gas turbine engine includes a first engine controller comprising a first motion sensor. The first motion sensor defines a first orthogonal coordinate system, and is configured for determining first motion sensor data indicating motion of the aircraft along at least one axis of the first orthogonal coordinate system. The system further includes a second engine controller comprising a second motion sensor spaced apart from the first motion sensor. The second motion sensor defines a second orthogonal coordinate system, and is configured for determining second motion sensor data indicating motion of the aircraft along at least one axis of the second orthogonal coordinate system. In addition, the second engine controller is communicatively coupled to the first engine controller such that the first engine controller receives the second motion sensor data.
