RADIO MANAGEMENT UNIT
The Radio Management Unit (RMU) is provided for radio controlling
purposes, but may be used as a back-up for PFDs, MFDs and EICAS.
The RMU display presents settings and modes for each radio (NAV
and COMM), transponder, and TCAS. In case of failure of the main
panel displays, the RMU may be selected to present navigation, engine
or systems information, as well as some EICAS messages. The
information presentation however may change, due to the size of the
RMU display. Also, some items of information may not be presented to
avoid display overload. For further information on RMU features, refer
to Section 2-18 − Navigation and Communication.
