This menu permits selective storage of the given
current position for the four digital trim controls in
order to return them afterward to their visual middle
points. This makes the last stored trim positions in the
respective middle positions of trim wheels for control
functions 1 … 4 available again following a model
memory location change or after long fl ight pauses.
This memory store process is effective on a fl ight-
phase specifi c basis for the currently active model
memory location and is not to be stored globally.
Therefore, as soon as fl ight phases have been
defi ned in the »Phase settings« and »Phase
assignment menus, the given active fl ight phase
will be displayed on the screen's bottom line. For
example:
