The navigation (NAV) control panels supply frequency inputs and test commands to these navigation radios:
· DME
· ILS
· VOR.
When you put a paired VOR or ILS frequency into the navigation control panel, it also goes to the DME interrogator. The DME tunes a DME frequency in the range of 108MHz to 117.95MHZ. Set the frequency on the navigation control panel for these audio outputs:
· VOR and DME station identification
· ILS and DME station identification.
