ABSTRACT:
An area navigation system capable of operating during an ILS approach to provide the pilot range and bearing with respect to the outer and middle markers for a front course approach, and with respect to the final approach fix and the end of the runway for a back course approach. The system operates by automatically connecting the # 2 NAV receiver to the RNAV during ILS operation while the ILS localizer converter is connected to the # 1 NAV receiver. At the same time the RNAV is disconnected from the left side indicator so this may be used for the localizer.
