Abstract:
The invention relates to a testing device (12) for checking the operability of a bow steer control unit (10) in an aircraft. The bow steer control unit has a plurality of input ports and a plurality of output ports, wherein at least one of the input ports of the bow steer control unit is connectable to a speed sensor, which provides a signal representing the actual speed of the bow wheel of the aircraft. The bow steer control unit outputs a blocking signal to be transmitted to a steering mechanism as soon as the detected actual speed of the bow wheel exceeds a predetermined bow wheel speed value. The testing device comprises a connection interface (14) to be connected to at least one input port of the bow steer control unit and a bow wheel speed simulating nit for generating a bow wheel speed simulation signal, which represents a particular simulated bow wheel speed value exceeding the predetermined speed value The generated bow wheel speed simulation signal is transmitted to the bow steer control unit via the connection interface. The output of the bow steer control unit in response to the received bow wheel speed simulation signal is then monitored.
