Active CLB Page
The CLB page is the active PERF page when the aircraft is in climb (below the
first CRZ FL).
The FMS speed modes are as follows:
• ECON is the most economical CAS/Mach for time and fuel trade-off,
based on the cost index entry (not editable).
• MAX CLB is the CAS that provides the maximum angle-of-climb (not
editable).
• EDIT is a flight crew-selected CAS and/or Mach. A CAS entry without a
specified Mach causes MMO to be the associated Mach. A Mach entry
without a specified CAS causes VMO to be the associated CAS.
The flight crew may activate any of these speed modes by pushing the LSK
adjacent to the speed displayed for that mode. If no mode is activated, the last
engaged mode will become active on engagement. ECON will be the default only
on power up on ground.
The CLB page provides time and distance predictions for achieving the selected
(PRED TO) altitude of 1R. If a flight crew entry is made in the PRED TO field, it
is displayed in large font. Otherwise, the FCP altitude is displayed in small font.
The time and distance predictions are displayed in large font for the active speed
mode. If ECON or EDIT speed mode is active, time and distance predictions for
MAX CLB mode are also displayed, but in small font.
If an altitude conflict exists between the FMS target altitude and the FCP selected
altitude such that the aircraft is between the two, ??? is displayed on the left side
of the title line.
