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.
OPC - Displays the Operational Program Configuration part number.
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.
Inactive Date Range - Displays the effectivity date range for the inactive navigation database. May be line selected to the scratchpad and inserted to the ACTIVE line while on the ground.
CO [Company] DATA - Displays the last 8 characters of the Airline Modifiable Information (AMI) part number.
DRAG/FF - Displays the airplane drag and fuel flow correction factors. Usually, the default data from the airplane policy file displays for flight crew verification. When the values must be changed, enter the word ARM in the scratchpad and transfer it to the DRAG/FF line. This arms the line for actual data and ARM DRAG/FF is displayed. Enter the required drag/fuel flow data in the scratchpad and transfer to the ARM DRAG/FF line. Drag-only entries must be followed by a slash (/). Fuel flow-only entries may optionally be preceded by a slash (/).
POS INIT - Displays the POS INIT page.
