The FMC must contain these pieces of software:
(a)
Operational program (OPS)
(b)
Operational program configuration (OPC) database
(c)
Navigational database (NDB).
(3)
You can load the navigational database into the left FMC and then do the FMC navigational database crossload procedure.
(4)
If you install a new operational program, the databases are deleted. You must install all the databases again after the operational program is installed.
(5)
When new operational program software (OPS) is installed the performance factors return to the default values for the production airplane.
