Abstract
A method and system for obtaining and displaying distance information to multiple DME ground stations using a single airborne transmitter-receiver and for displaying groundspeed to one of the stations. A DME is time multiplexed between two channels and display-memory means, the distance value being held in the display corresponding to each channel until that channel and the display corresponding thereto is updated or until a predetermined period of time has elapsed. Further, a DME which provides a distance data output in both search and track modes is multiplexed between primary and secondary channels and display-memory means, and is permitted to go into track on the primary channel but only into search on the secondary channel. When the system is on the secondary channel appropriate information is stored and the DME is returned to primary channel operation in the track mode.
