Climb Performance pages

ACT MODE

CI

Shows the active speed mode as either managed or selected

Shows the cost index as entered on the INIT A page

MANAGED

PRESEL

Shows the FMGS computed ECON speed/Mach

Shows the PRESEL as long as the Climb phase is not active. If the Climb phase is active it shows the FCU selected speed or Mach.

If a Pre select speed is entered, an astrix is placed around the Managed Speed value at  LSK  3. Pressing the LSK  3L thereafter will reinstate the managed speed and  return brackets back to the PRE SEL line

Entering a Pre select speed will cause the FCU to initialize to that speed at the start of the Climb phase, and the aircraft will then be in selected speed mode.
