Block of diodes and switching (BDP-26SK) is designed for avionics upgrade programs which require no more than switching of four navigation data sources into one CDI indicator with an OBS resolver and with one added CDI repeater.
Block is primarily designed to interconnect the navigation system consisting of dual VOR/ILS receivers and single GPS and TACAN system.
The outputs of the unit are the analog signals for CDI indicators - KI206 for pilot and KI207 for the copilot.
The block switches between the navigation data source according to the position of the corresponding switch and indicates the selected information on the annunciators.
Block respects the priority of the displayed navigation information according to the civil aviation regulations.
