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-
20
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
First, you have to set up the different fl ight phases,
1.
i.e. you assign names to phases 1 … max. 8.
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. The
programming of helicopters begins with either
the »
Basic settings, model
« menu, if you wish
to set up autorotation or, otherwise, with the
»
Phase settings
« menu.
In the second stage, you use the »
2.
Phase
assignment
« menu to set up the required "phase
switches".
Once these are set, you can then move to the
3.
fl ight phase-dependent menus (see the tables
below) to start programming the settings for the
individual fl ight phases.

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 it may be desirable to use the
»
Suppress codes
« menu (see page 74) to remove
non-alterable menus from the multi-function list
while programming fl ight phases. Two examples of
fl ight phase programming can be found in the text
beginning on page 288.
