EFIS DISPLAY
FLIGHT MANAGEMENT (FM) SOURCE SWITCHING
In normal setting (FM normal operation), each PFD and
ND, via each related Display Management Computer (DMC),
displays EFIS data from the onside Flight Management
(FM) part.
If an FM has failed, a white "OPP FMGC IN PROCESS"
message is displayed in the corresponding MCDU
scratchpad showing an automatic switching to FM single
operation.
The PFD display remains operational.
The ND display also remains operational provided the
selected range and mode is identical on both NDs.
In other cases, a red "MAP NOT AVAIL" message is
displayed on the corresponding ND, with an amber
"SELECT OFFSIDE RNG/MODE" request.
MCDU FAILURE
If a Multipurpose Control and Display Unit (MCDU)
failure occurs on side 1 or 2, as long as the
transmitting FM is healthy, the transmission to the
EFIS continues despite the loss of this MCDU.

SELF EXAMINATION
What does the filled magenta circle on the PFD
represent?
A - Located on the altitude scale, it
represents the altitude constraint.
B - Located on the speed scale, it
represents the ECON speed target.
C - Located on the altitude scale, it
represents the linear vertical deviation.
What is the FM information displayed on the ND in
ARC, PLAN and ROSE-NAV modes?
A - Flight plan data, A/C present position
and wind characteristics.
B - Flight plan data, A/C present position
and autotuned radio navaids.
C - Flight plan data, Decision Height and
crosstrack deviation.

DATA BASE LOADING
GENERAL
Every 28 days, a new navigation data base must be
loaded into each Flight Management and Guidance
Computer (FMGC) with the help of a portable floppy
disk data loader.
In fact, the floppy disk received by the company
contains 2 navigation data bases: One corresponds to
the present period of 28 days and the other to the
next period.
During the operation, the two data bases are loaded.
The operation must be performed independently for each
FMGC.
The data base loading can also be used during
maintenance operations as it enables some Flight
Management (FM) problems to be solved (for example,
missing information on MCDU FM pages).
The basic loading (with the portable floppy disk data
loader) can be performed into either FMGC 1 or FMGC
2. Then, the crossloading function allows the new
navigation data base to be transferred from this FMGC
to the other one.
The following table indicates the loading time for one
FMGC depending on the loading type.
