With this, all helicopter-specific settings which can be
made on the "workbench" are now completed. The
further fine-tuning must take place in flight. The flight-
tested, (hopefully) minor (digital) trim settings are
automatically saved.
Larger deviations should first be mechanically adjust-
ed or adjusted according to the previously discussed
settings.
Further settings
Following this programming example, you have pro-
vided a helicopter with a basic adjustment for the
hovering training and simple trips. Depending on your
knowledge and experience as a pilot, additional func-
tions can, of course, also be activated.
If you want to fly at different speeds and with different
trimming, you activate the so-called "flight phases",
which can be called with assigned switches as an al-
ternative to the previously described "normal phase".
For this purpose, first open the menu ...
»Phase settings«
... whereby the symbols appearing in the second
column, sometimes only after a switch assignment in
the »Phase assignment« menu, have the following
meanings:
"–": no phase switch present
"+": phase switch present
"": currently active phase
Autorot Autorot
Phase 1
Phase 2
Phase 3
Phase 4
Name Fl.ph.Tim.
However, consider in advance whether these are to

be implemented with individual switches or, more
reasonably, with 3-way switches because as many as
7 flight phases can be activated in addition to the au-
torotation phase. The latter possibility is more logical
and usually more clearly laid out.
The "Autorot" line is already selected in the figure
above. When activated, the autorotation phase always
has precedence over any other phases you assign
switches to.
However, in the "Name" column you first assign
"meaningful" names to Phases 1 to 3, which are
adopted from a list. These identifications serve for the
better differentiation and are shown later in the base
screen and for all flight-phase dependent menus, for
example:
Autorot Autorot
Phase 1 Normal
Phase 2 Hover
Phase 3 Speed
Phase 4
(page 158)
Name
Then, in the fourth column from the left, enter the
switching time with which FROM phase should switch
TO the next respective phase. Approximately 1 s
should suffice:
Autorot Autorot
Phase 1 Normal
0.1s Phase 2 Hover

0.1s – Phase 3 Speed
0.1s – Phase 4
0.1s – Name
0.1s –
This value can also be adjusted later according to
Sw.time
your personal preferences. Please observe in the
process that TO the autorotation phase, whose name
is defined as "Autorot", is switched without a time de-
lay. If necessary, enter the time with which a change
FROM the autorotation phase to a different phase
should be affected.
In order to be able to switch between the individual
flight phases, the assignment of the individual switch-
es or the three-stage switch is necessary.
The assignment of the switch takes place in the
menu ...
»Phase assignment«
Under "C" and "D", for example, assign the one of the
two standard 3-way switches mounted into the switch
panels, e. g.:
0.1s

0.1s –
0.1s –
0.1s –
0.1s –
Fl.ph.Tim Sw. time
Now the given switch position must be assigned to
the respective flight phase in the »Phase settings«
menu. Since these phases already have names, the
name «1 Normal» will initially appear at the right in
the display. If the already assigned autorotation switch
was activated, the following warning message ap-
pears in the display:
1.1s

1.1s –
1.1s –
1.1s –
0.1s –
