The mc-22s enables you to program a maximum of
three groups of settings within any one helicopter mo-
del memory in addition to the auto-rotation fl ight pha-
se, which can be set up in the »
Auxiliary switch
«
menu; the settings typically differ from each other in
order to cater for different stages of a fl ight.
When setting up fl ight phases you start in this menu
point, where individual phases are assigned names,
and a transition time can be set to provide a smooth
transition from one phase
into
the next.
“Name” column
The fi rst line, i.e. the top fl ight phase, is reserved for
Auto-rotation; see »
Auxiliary switch
« menu. Conse-
quently the pre-set name
cannot
be altered.
Select Phases 1 to 3 in turn, then press the rotary
control and select the most suitable phase name for
them from the on-screen list. Press the rotary control
to confi rm your choice. Note that you do not necessa-
rily have to start with Phase 1 and continue in turn.
However, “Phase 1” is always the “normal phase”, i.e.
this phase is always active if:
• no phase switch has been programmed in the
»
Phase assignment
« menu, and
• no phase has been assigned to particular switch
combinations.
The phase name «Normal» would therefore be a sen-
sible choice for “Phase 1”. The names themselves
have absolutely no technical signifi cance in terms of
programming; their only purpose is to help you iden-
tify them in the course of further programming, and
know which fl ight phase is switched on at any one
time. The phase name is included in all phase-speci-
fi c menus (see list on page 76) and is also shown in
the basic display.
“Switch time” column
When you switch between fl ight phases, it is advisab-
le to program a “soft” transition
into
(!) the next pha-
se; this is carried out by entering a transition time in
the inverse fi eld in this column; the range available is
0 to 9.9 sec. The mc-22s also allows you to set diffe-
rent transition times for switching from, say, Phase 1
to Phase 3, and from Phase 3 to Phase 1.
However, for reasons of safety there is never any de-
lay when you switch
into
the auto-rotation fl ight pha-
se. The arrow “
” in the column “switch time” indica-
tes that a delay time can still be set
out of
(!) auto-ro-
tation and
into
(!) any other phase.

„Autorot“:
The transition time from this phase into
any other is 2.0 sec. Conversely, there is
always zero (0.0 sec) delay when swit-
ching into Auto-rotation.
„Phase 1“: The transition time into this phase from
phase 2 (and 3*) is set to 3.0 sec, giving
a smooth transition.
„Phase 2“: The transition time into this phase from
phase 1 (and 3*) is set to 1.0 sec.
* In our example Phase 3 is not in use.
Unequal transition times as shown in our example
can be useful when switching between fl ight phases
which differ widely, such as between aerobatics and
normal fl ight.
Note:
The “transition time” set here also applies to the »
He-
licopter mixer
« menu; see page 90, to avoid abrupt
changes between phase-specifi c mixers.
The fi nal stage is to select the »
Phase assignment
«
menu and defi ne the “phase switches” you wish to
use. Once these are set, you can get started on pro-
gramming the settings for the individual fl ight phases.
“Status” column
The phases which have already been assigned to
a switch are shown in the right-hand column of the
screen display:

Note:
A useful aid when programming different fl ight pha-
ses is the “Copy fl ight phase” option which you will
fi nd in the »
Copy / Erase
« menu. The fi rst step is to
establish the parameters for a particular fl ight phase;
you then copy these settings into the next fl ight phase
where they can be modifi ed to meet the requirements
of the new stage of fl ight. Note that the Auto-rotation
fl ight phase cannot be copied.
