During FM normal operation, the F-PLN is continuously downloaded in the MCDU memory: the
BACK UP NAV function links the MCDU of the failed FM to its onside IRS.
All navigation data related to the MCDU F-PLN are displayed on the associated ND.
BACK UP NAV function is activated on the MCDU MENU page by depressing the NAV B/UP
prompt.
The MCDU back-up F-PLN may accept a maximum of 150 waypoints. It displays only point to
point F-PLN (radial, pattern, heading leg... cannot be part of the MCDU F-PLN).
No secondary or temporary F-PLN exists.
These are five pages available while BACK UP NAV is active :

line 1 to line 5 Display consecutive waypoints with their associated latitude/longitude.
If a waypoint is to be overflown, an overfly symbol ( ) is displayed after the
identifier.
If a turn is specified into the next leg, a large font arrow is displayed after
the identifier.
Label lines contain the bearing, time to go and distance to the next
waypoint displayed in small font.
white bearing
green time to go and distance
BRG Between FROM and TO waypoints : True or Mag
depending on the TRUE pushbutton position. T
is displayed when the bearing is true referenced.
Between other waypoints : out bound true track
of the great circle joining the 2 related waypoints,
independant of TRUE pushbutton switch.
TTG HHMM limited to 9959. Time between the 2 related
waypoints.
DIST NM limited to 9999.
line 6 DEST DEST airport identifier and associated latitude/longitude.
DIST to destination is computed as the direct distance from the aircraft to
the active waypoint plus the along flight plan distances.
time to go to destination is computed as distance to destination divided by
ground speed.
TTG and DEST are dashed if aircraft position is unavailable.
B/UP F-PLN (DIR TO) PAGE
The pilot calls up this page using the DIR key on MCDU while BACK UP NAV is active and aircraft
position is valid.

TITLE B/UP PROG is displayed in a white large font.
line 1 OVHD/ALT Displays the identifier of the last sequenced waypoint
and the altitude at the time of the sequence.
line 2 BRG/DIST/TTG/TO Allows the pilot to enter an existing MCDU F-PLN
waypoint identifier or LAT/LONG or IDENT/LAT/LONG.
MCDU then computes bearing, distance and time to go
to that waypoint from the present position.
The pilot may modify or clear this entry (2R field).
BRG : True or magnetic outbound track of
the great circle joining aircraft present
position to the entered waypoint :
dependent on the TRUE pushbutton
switch position.
DIST : limited to 9999.
TTG : HHMM limited to 9959. time to go
to the entered position computed
assuming current ground speed.
These fields are displayed in a green small font.
They are dashed if present position is unavailable.
