Could someone comment on this?
In compliance with Section 8.8.2 (4) of the FCOM “Check of engagement and
disengagement of the Go-around mode” the crew could arm the Go-Around mode by pressing
the APPROACH and GLIDE SLOPE buttons on autopilot control panel. It should be noted that
these actions are only prescribed to be performed on the ground during the preflight inspection
of the autopilot and cannot be performed in flight according to the FCOM.
Why only on the ground?
