The example from FCOM only relates to Altitude and FL but why not speed? For example I call “Speed 250 blue” or “Heading 180 blue”. Also “Speed 250 magenta”. I understand the Guidance mode is either Selected or Managed however there is no Standard Call-out for “Selected”, “Managed” relates to a request from the PF to PM to push a knob on the FCU when the AP is off. The only way we can cross check the change in guidance mode is by the colour.
