D. Prepare the media disk(s).
   (1) Get the media disk(s) from the storage box in the cockpit.
NOTE: It is not mandatory to keep the database media disk(s) in the storage box in the cockpit. Thus, you can keep the database media disk(s) in the storage area.
   (2) Make sure that the Part Number(s) (P/N) written on the media disk(s) is(are) the same as the P/N(s) written in the airline configuration management-document.
     (a) If the media disk(s) is(are) not available or not the correct one(s), contact your airline engineering department to get the correct part number(s) applicable to the aircraft.
Subtask 22-70-00-280-074-C ** ON A/C NOT FOR ALL
E. Check of the P/N(s) of the Software Component(s) (Pre-loaded to the Related FMGC)

NOTE: If the software component(s) that you upload is(are) not correct, the FMGC will not accept the uploading.
NOTE: If you upload the FMS operational-program software-component, it is necessary to upload these software components again:
  • The navigation database
  • The airline modifiable-information file
  • The operational program-configuration file
  • The performance database
  • The magnetic variation database.
    On the Multipurpose Control & Display Unit (MCDU), if you push the MCDU FM mode key, the "NOT ALLOWED" message will come into view on the scratchpad.
  • Until you upload the software components again
  • If the FM software component is not compatible with the Flight Guidance (FG) software component.
   (1) Do a check of the P/N(s) of the software component(s):
