_________________________________________________________
 1.  General_______
 A.  This procedure contains these tasks:
 (1)  
Installation of the FMC software with a data loader.

 (2)  
Crossload of the FMC navigational database.

 (3)  
Configuration check of the FMC software.

 (4)  
Installation of the FMC performance factors.

 B.  To read about software installation times and data loaders, do this task: On-Airplane Software Installation (AMM 20-15-11/201).
 C.  The airplane must be on the ground before you can do these tasks.
 D.  Some airlines like to keep the circuit breaker for the airborne data loader open when the data loader is not necessary. This increases the length of time that the data loader is serviceable.
 E.  The procedure to download FMC BITE data is in the Flight Management Computer BITE Data Download - Maintenance Practices (AMM 34-61-11/201).
