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:

Storing trim positions
The model has been fl ight tested and trimmed
during the test fl ights. Current trim positions are
now displayed in the column "Trim Pos." located
approximately in the middle of the display. (The trim
range is about ±30 % of total control travel.) The right
column displays trim memory content, currently fi lled
uniformly with 0 % because values have not yet been
stored. Therefore, the display appears as follows:

pad to move to the line where a trim value is to be
written into trim memory, e.g. the elevator trim value:
