Abstract: An avionics unit for an aircraft including a communications interface arranged to interface with one or more other avionics units. The communication interface is arranged to transmit a signal having a first state indicating a fault condition of the avionics unit to the one or more other avionics units if the first state persists for a predetermined time. A processor is arranged to modulate an output at the communication interface to provide a modulated signal to indicate a characteristic of a present state of the avionics unit with respect to the fault condition. The modulated signal includes the first state and a second state, different from the first state, wherein, in the modulated signal, the first state has a duration less than the predetermined time
