Triple FMC Failure
In the unlikely event all FMCs become inoperative, the EICAS advisory message
FMC is displayed. There is a loss of PFD mini-map displays, ND map displays,
loss of the CDU pages on the MFD and no LNAV or VNAV operation or guidance.
The TCPs provide the capability to enter a single Latitude/Longitude waypoint.
The TCPs then provide track, distance to go, and groundspeed to the entered
waypoint. The ability to tune the left integrated navigation receiver is provided
through the TCPs. Left side ILS or GLS deviations are then displayed on the
ISFD.
Autothrottles should still be available and may be used in conjunction with any
valid autopilot roll and/or pitch mode.
(Refer to Chapter 11, Section 50, Alternate Navigation System Description
, for
additional information.)
