Abstract: A diagnostic display system is provided for diagnosing avionics components of an aircraft using an interactive display accessible to a user in real time. A central diagnostic module receives at least one signal from a plurality of sensors for the aircraft, and at least one parameter from a related avionics system associated with the aircraft. A component information module provides operational status information about at least one of the avionics components of the aircraft, and provides a detailed operational status configuration of each avionics component using a plurality of status messages stored in a database via a network. The central diagnostic module assesses a current operational status of the aircraft by evaluating the operational status configuration illustrated in the display for establishing a visual link between the status messages associated with the avionics components of the aircraft.
