Introduction
The cruise phase starts at the top of climb.
During cruise, the primary FMC pages are:
• RTE X LEGS
• CRZ
• PROGRESS
The RTE LEGS pages are used to modify the route. The CRZ pages display
VNAV related data. The PROGRESS pages display flight progress data. During
cruise, the specific page listed below is used to:
• POS REF page – verify the FMC position
• RTE DATA page – display progress data for each waypoint on the RTE
LEGS page
• WINDS page – enter forecast wind and temperature
• REF NAV DATA page – display data about waypoints, navaids, airports,
or runways, and can be used to inhibit navaids
• RTE X page – use to select a route offset
• FIX INFO page – display data about waypoints. Page data can be
transferred to other pages to create new waypoints and fixes
• SELECT DESIRED WAYPOINT page – shows a list of duplicate
waypoints from the navigation database. The flight crew selects the correct
waypoint from the list
• POS REPORT page – display data for a position report
The CLB page changes to CRZ at the top of climb. The CRZ CLB and CRZ DES
pages change to CRZ at the new cruise altitude. The CRZ page changes to DES at
top of descent.
LNAV Modifications
This section describes typical techniques to modify the route. The modifications
include:
• add and delete waypoints
• change waypoint’s sequence
• remove discontinuities
• intercept a course
