RADIO MANAGEMENT PANEL PRESENTATION
RADIO MANAGEMENT PANEL (RMP) DESCRIPTION
The RMPs are used for the selection of radio
communication frequencies. They are also used for the
standby selection of radio navigation frequencies in
back-up mode.
3 RMPs are used for frequency selection, each one can
control any VHF (HF) frequency.
Note: the third RMP is optional.
The 3 RMPs permanently dialog so that each RMP is
informed of the last selection made on any of the other
RMPs. If two RMPs fail, the remaining RMP controls all
the VHF transceivers.
The transmission of data to the communication and
navigation systems and the dialog between the RMPs are
performed through ARINC 429 buses.
WINDOWS
There are 2 display windows:
- The active window displays the operational
frequency
- The standby/course window displays the standby
frequency or the course in back-up navigation
mode.
The windows are liquid crystal displays with a high
contrast.
TRANSFER P/B
When the transfer key is pressed, the standby frequency
becomes the operational frequency, and the operational
frequency becomes the standby frequency.
COMMUNICATION KEYS
There are 6 pushbutton keys for the radio communication
systems. 3 of them are used for VHF, the 3 others for
HF.
The AM key controls the selection of the AM mode for
HF transceivers provided that HF1 or HF2 is selected.
When a key is pressed, the relevant active and the
standby frequencies are automatically displayed in the
dedicated windows.
SEL INDICATOR
Although one RMP can control frequencies of any
transceiver, each RMP has dedicated systems.
The normal configuration is:
- RMP1 allocated with VHF1, VHF3 and HF1, if
installed,
- RMP2 allocated with VHF2 and HF2, if installed.
If the optional RMP3 is installed, it will be allocated
with VHF3 and HF systems which are no longer dedicated
to RMP1 or RMP2.
The SEL indicator light will come on white on the RMPs
involved, when an RMP takes control of a non dedicated
system frequency selection.
For example, if VHF2 is selected on RMP1, the SEL
indicator lights come on on RMP1 and RMP2.
DUAL SELECTOR KNOB
The dual selector knob is used for the selection of
the frequency/course displayed in the standby/course
window.
