Q

What are the settings of the LDG ELEV sel knob?

A

AUTO: The pressurization system uses the FMGS data to construct an optimized pressure schedule. To exit the AUTO position, pull out and turn the selector.

Other positions: The pressurization schedule does not use the landing elevation from the FMGS, but instead uses the landing elevation selected with this knob (from – 2000 to + 14000 feet) as its reference. The LDG ELEV selector scale is only given as an indication; refer to the ECAM information for accurate adjustment.
