Page Title
The page title displays the type of climb. Normally, the title displays ECON for
the economy climb mode. Fixed speed climbs modify the title.
XXX LIM CLB indicates the limit speed, XXX, is based on leading or trailing
edge flaps:
• target speed is 5 knots below trailing edge flap placard speed
• speed is limited to 230 kts if leading edge devices are not completely
retracted
ECON indicates the speed is based on a cost index.
MAX RATE indicates the speed is based on the maximum altitude over the
shortest period of time.
MAX ANGLE indicates the speed is based on the maximum altitude over the
shortest horizontal distance.
Fixed climb speeds display XXXKT for a fixed CAS climb speed or M.XXX for
a fixed Mach climb speed profile. Reasons for fixed speeds are:
• takeoff/climb acceleration segment constraints
• waypoint speed constraints
• an altitude constraint associated with a speed constraint
• a speed restriction
• a crew entered speed.
Displays ACT when the climb phase is active.
2
Cruise Altitude (CRZ ALT)
The cruise altitude from the PERF INIT page is displayed. The altitude can be
changed by two methods:
• a new altitude can be manually entered from the CDU at any time.
Changing the altitude in this manner creates a modification.
• setting the MCP altitude above the current FMC CRZ altitude, provided
no intermediate altitude constraints exist between the current airplane
altitude and the MCP target altitude. Selecting the new altitude on the
MCP and pushing the altitude intervention button places the new
altitude in the CRZ ALT data line. Entering a new cruise altitude in this
manner does not create a modification.
3
Target Speed (TGT SPD)
Displays computed values or manually entered values for the selected mode.
Displays XXX/MCP when speed intervention is active and plan is active.
Airspeed and/or Mach may be entered using the keyboard. Title will display
manually entered value.
