How do I program a fl ight phase?
The concept of fl ight phase programming
General information on fl ight phase programming
During a fl ight, you will often want to apply different
settings – e.g. fl ap or trim settings for a fi xed-wing
aircraft or collective pitch and throttle servo settings for
a helicopter – at particular times in the fl ight (e. g. take-
off, approach, hover, auto-rotate, etc.). With mc-32
HoTT, you can access such presets automatically using
switches or control switches.
Flight phases are also of great utility during fl ight testing.
You can confi gure various set-ups and then switch
between them during the fl ight: this enables you to
identify the most appropriate program set-up for your
model quickly and easily.
The basic programming procedure is a three-stage
process
1.
First, you have to set up the different fl ight phases,
i. e. you assign names to phases 1 ... max. 7. Each
name is then shown in all phase-specifi c menus and
also on the basic display. To avoid abrupt transitions
when switching between the various phases, you can
also program a period of time during which a "soft"
transition to the next phase takes place.
For fi xed-wing aircraft programs, these settings
are made in the "Phase settings" menu. For heli
programs, you either start with the "Base setup
model" menu if you wish to set up autorotation or,
if not, you also start programming with the "Phase
settings" menu.
2.
In the second stage, you use the "
Phase
assignment" menu to set up the required "phase
switches".

3.
Once these are set, you can then move to the fl ight
phase-dependent menus (see the tables below) to
start programming the settings for the individual fl ight
phases.
List of fl ight phase-relevant menus for fi xed-wing
programs:
Menu
"Control adjust"
"Dual Rate / Expo"
"Channel 1 curve"
"Phase settings"
"Phase assignment"
"Phase trim"
"Non-delayed channels"
"Fl. phase timers"
"Wing mixers"
"MIX active/phase"
List of fl ight phase-relevant menus for helicopter
programs:
Menu
"Control adjust"
"Dual Rate / Expo"
"Channel 1 curve"
"Phase settings"
"Phase assignment "
"Non-delayed channels"
"Fl. phase timers"
"Helicopter mixers"
"MIX active/phase"
All other menus are model-specifi c and thus cannot
be programmed separately for each fl ight phase.
Accordingly, changes you make in all other menus apply
uniformly to all fl ight phases for that specifi c model.

In some cases you may wish to use the "Suppress
menus" menu (see page 67) to remove the non-specifi c
96
menus from the multi-function list when programming
108
fl ight phases. A practical example of fl ight phase
116
programming can be found on page 256).
