Section 3.0 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the
RS12/RS24 Remote Switch.
3.2 General
The RS12/RS24 provides remote switching of navigation or audio signals to allow
system expansion or interconnection. The RS12/RS24 requires no operator interaction.
Once installed, it operates independently to provide the required switching functions.
If used for NAV switching (such as two sources to a common indicator), it must be
clearly marked and placarded in the aircraft. External annunciation of NAV source must
comply with section 2.3.4 of this manual.
If used for GPS/LORAN/VLF switching, the unit may have to be wired to return to the
VOR/ILS mode when the navigation receiver is channeled to an ILS frequency. Check
local aviation regulations regarding this requirement.
NOTE: ILS reversion mode is not applicable in Canada for NAV/GPS installations.
3.3 Limitations
The RS12/RS24 series remote switch imposes no limitations on the original airframe.
3.4 Emergency Procedures
The RS12/RS24 series remote switches do not affect the emergency procedures of the
aircraft. Flight personnel should be made aware of the function of the RS12/RS24, if it
is used to switch navigation signals.
3.5 Performance
The RS12/RS24 series remote switches do not affect the performance of the aircraft.
