Set Default Vertical Speed Rate
Upon activation of the altitude preselect function, either the vertical rate set into the VS SET display, or a
default vertical rate will become active. If no vertical rate is set when the altitude preselect function is

 If the setting is "AND", then a single switch input is used for both the V NAV and H NAV
disconnect functions.
