Scope of Functionality
16 RN3320 / RN3330 DV60603.03 Issue 02 November 2019
Signal Interface (Indicators)
Indicators made by other manufacturers and with standard ARINC resolver are compatible with the
VOR/LOC converter of the navigation receiver and may be used.
Additional Pointers and Flags
It is possible to connect up to two analog instruments parallel to the indicator without altering the
navigation receiver.
For example, instruments with:
•VOR/LOC pointer, VOR/LOC warning flag.
•TO/FROM indication.
•GS pointer and GS warning flag.
Autopilot (VOR/LOC and GS)
The navigation receiver has outputs for connection of an autopilot.
VOR/LOC and GS Super Flags
The converted VOR/LOC and GS signals can be feed to the super flag inputs of course guidance
systems (controlled by the super flag control outputs).
For further details please see "Aircraft Wiring" page 35.
ILS Mode Control Function
The ILS mode control function can be used to operate an Instrument Flight Control (IFC) system or
similar systems, such as automatic switching of an autopilot to VOR and ILS modes.
For further details please see "Aircraft Wiring" page 35.
Audio Output
The audio output of the navigation receiver is set to a symmetrical audio output on delivery.
•A symmetrical selection system or head set can be connected.
The audio output can also be changed to an asymmetric audio output.
For further details please see "Aircraft Wiring" page 35.
Self-Test
The self-test of the navigation receiver can be initiated by the user.
•With the TEST function through a control device a functional check will be started.
•The VOR/LOC evaluation and GS evaluation will be examined.
