Active CRZ Page
The CRZ page is the active PERF page when the aircraft is in cruise, including
any step climbs.
The FMS speed modes are as follows:
• ECON is the most economical cruise Mach for time and fuel trade-off,
based on the cost index entry (not editable).
• MAX END is the CAS which provides the maximum endurance (time
aloft), and also provides the minimum drag (not editable).
• EDIT is a flight crew-selected CAS or Mach. Prior to a selection, brackets
are displayed.
If a speed mode is preselected on the PRESELECT CRZ page, that mode is
automatically activated when the CRZ page becomes the active PERF page. If no
mode is preselected, then the previous active mode remains active by default (or
if that mode is not available in cruise, ECON is activated). Thereafter, the flight
crew may activate any of these speed modes by selecting the LSK adjacent to the
speed displayed for that mode.
Selecting an edit speed in CRZ will not automatically carry the cruise speed edit
into descent.
The CRZ page provides time and distance predictions to the next step climb point
in 1R in large font (not editable). If the aircraft passes that point before the FCP
altitude is raised for the step, the time and distance is replaced by STEP NOW. If
the next step climb point is within 200 nm of the top of descent, the label for this
field is replaced with TO T/D, and the time and distance to the predicted top of
descent is displayed in 1R.
If a time constraint is inserted at a flight plan waypoint, TIME is displayed on the
left side of the title line to indicate that the ECON speed is adjusted accordingly.
If an altitude conflict exists between the FMS target altitude and the FCP selected
altitude (aircraft is between the two), ??? is displayed on the left side of the title
line to indicate the conflict.
