FMS SOURCE SELECTION ON THE MFD
As explained on the Display Control Panel (DCP) description (see
section 2-18-40), pressing the FMS Button on that panel selects the
FMS as navigation source for the PFD and MFD.
On airplanes equipped with dual FMS, pressing the FMS Button (on
the Display Control Panel) for the second time selects the opposite
side FMS as navigation source for the on-side EHSI (and for the on-
side MFD MAP). Pressing the FMS Button once again will restore the
normal operation: FMS 1 information presented on the PFD 1 (and
MFD 1) and FMS 2 information presented on the PFD 2 (and MFD 2).
However, on airplanes equipped with dual FMS it is possible to select
the opposite side FMS as MFD navigation source even if the FMS is
not selected as navigation source for the PFD.
In this case, pressing the MFD Bezel Button adjacent to the MFD SRC
label (presented on the MFD submenu), the on-side MFD will display
the opposite side FMS data. This label is not presented if the FMS is
already selected as navigation source for the PFD.
