How do I program a fl ight phase?
The meaning of fl ight phase programming

General notes on fl ight phase programming
Often there are particular stages in a fl ight where you
always need to use particular settings: perhaps diffe-
rent fl ap settings for launch and landing with a fi xed-
wing aircraft, or different collective pitch and throttle
settings for hover and auto-rotation with a helicopter.
The mc-22s enables you to program these different
settings and call them up automatically using an ex-
ternal switch or even a control switch.
Another very useful application for fl ight phases is the
fl ight testing procedure with a new model. You can set
up different fl ight phases with alternative control sur-
face settings, then switch between them in fl ight in or-
der to establish the most effective set-up for the mo-
del in question.
The basic programming procedure is carried out
in three stages
1. First you have to set up the different fl ight phases,
i.e. you assign names to individual phases which
are then included in the basic screen display. It is
also possible to program a time frame for a “soft”
transition into the next phase, so that the mo-
del moves smoothly from one phase to the next,
rather than abruptly.
For fi xed-wing model aircraft these settings are
programmed in the »
Phase setting « menu. In the
Heli program you start in the » Auxiliary switch «
menu if you wish to set up an auto-rotation facility,
otherwise you also start programming in the »
Pha-
se setting « menu.
2. In the second stage you set up the required “pha-
se switches” in the » Phase assignment « menu.
3. Once these preliminary steps have been comple-
ted, you can move to the specifi c phase menus
and start programming the settings for the indivi-
dual fl ight phases, as shown in the tables below.
List of fi xed-wing menus which are variable sepa-
rately for each fl ight phase:
Menu Page
»Control adjust« 58
»Dual Rate / Expo« 64
»Phase setting« 78
»Phase assignment« 80
»Undelayed channel« 81
»Wing mixers« 84
»MIX active/phase« 108
List of helicopter menus which are variable sepa-
rately for each fl ight phase:
Menu Page
»Control adjust« 60
»Dual Rate / Expo« 66
»Channel 1 curve« 70
»Auxiliary switch« 75
»Phase setting« 79
»Phase assignment« 80
»Undelayed channel« 81
»Helicopter mixer« 90
»MIX active/phase« 108
All the other menus are model-specifi c, i.e. they can-
not be programmed separately for different fl ight pha-
ses. All changes you make in the other menus app-
ly equally to all fl ight phases. In some cases you may
wish to remove the non-specifi c menus from the mul-
ti-function list when programming fl ight phases; this
is carried out in the »
Suppress Codes « menu (see
page 49). An example of fl ight phase programming
can be found on page 134.
