INDEX

Push - displays the INIT/REF INDEX page.

Engine Rating (ENG RATING)

Displays the engine thrust stored in the FMC performance database (e.g., 20K,

22K, 24K, 26K or 27K).

ACTIVE Date Range

Displays the effectivity date range for the active navigation database.

Database activation is accomplished by pushing the proper date range prompt to

copy that date into the scratchpad. The scratchpad date may then be transferred to

the ACTIVE database line. The previous active date moves down to the inactive

date line.

The ACTIVE label appears above the active navigation database date. No label

appears above the inactive navigation database date. The navigation database date

can be changed only on the ground. Changing the navigation database removes all

previously entered route data.

When an active database expires in flight, the expired database continues to be

used until the active date is changed after landing.

Inactive Date Range

Displays the effectivity date range for the inactive navigation database.

Supplemental Data (SUPP DATA)

Displays the effective date of supplemental data. Blank if supplemental database

is empty.

VIA

The VIA column displays the route segment to the waypoint or termination

displayed in the TO column. Enter the path which describes the route segment

between the previous waypoint and the segment termination.

Enter an airway in the VIA column and box prompts are displayed in the TO

column if the previous TO line contains a waypoint on the airway.

Valid entries can also include procedures or DIRECT. Procedures are normally

entered through selections on DEPARTURES and ARRIVALS pages. DIRECT is

normally entered as a result of entering a TO waypoint first.

Valid airways must:

• contain the fix entered in the TO waypoint, and

• contain the previous TO waypoint, or

Dashed prompts change to DIRECT if the TO waypoint is entered first.

11.40.19

Flight Management, Navigation -

FMC Preflight

Boeing 737 Operations Manual

Dash prompts appear for the first VIA beyond the end of the route.

Invalid VIA entries display the scratchpad entry INVALID ENTRY.

Invalid VIA entries are:

• airways and company routes which do not contain the TO waypoint of the

previous line

• airways or company routes that are not in the navigation database.

When entering airways, the beginning and ending waypoints determine if the

entry is valid. The route segment must contain the waypoint entered in the TO

position. The TO waypoint of the previous route segment must be the same as the

beginning point of the current route segment, or a route discontinuity is created

between the segments.

Entry of a SID or transition automatically enters the VIA and TO data for the route

segments of the SID. A SID automatically links to the next route segment when

the final SID waypoint is part of the route segment.

LACRE3.VAMPS is an example of a SID selection made on the DEPARTURES

page.

V2 is an example of airway entry.

Enter the end point of the route segment specified by the VIA entry.

Entry of a waypoint in the TO column without first entering a VIA airway displays

DIRECT in the VIA column.

Box prompts indicate that an entry is required.

Valid waypoint entries for a DIRECT route segment are any valid waypoint, fix,

navaid, airport, or runway.

Valid waypoint entries for airways are waypoints or fixes on the airway.

Dash prompts appear on the first TO waypoint following the end of the route.

ACTIVATE

Pushing the ACTIVATE key arms the route for execution as the active route.

When the EXEC key is pushed, the route becomes the active route and the

ACTIVATE prompt is replaced with the next required preflight page prompt.

Push - prepares the selected route for execution as the active route.

Activation of a route is required for completion of the preflight.

Displayed on inactive route pages.
