Identification
Most of the data on this page is for flight crew verification. Active data and drag/fuel flow can be modified.
The flight crew verifies FMC data, selects the current navigation database, and checks or modifies drag and fuel flow factors on the Identification page.
MODEL - Displays the airplane model from the FMC performance database.
NAV DATA - Displays the navigation database identifier.
OP PROGRAM - Displays the operating program identifier.
DRAG FACTOR - Displays the airplane drag correction factor expressed as a percentage. Maintenance action is required to modify the drag factor.
INDEX - Displays the INIT/REF INDEX page
ENGINES - Displays the engine model from the FMC performance database.
ACTIVE - Displays the effectivity range for the active navigation database.
The active navigation database can be replaced with the inactive database while on the ground. Changing the navigation database removes all previously entered route data.
