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
mx-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. 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.
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 fl ight 3.
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 you may wish to use the "
Suppress
menus " menu (see page 67) to remove the non-specifi c
menus from the multi-function list when programming
fl ight phases. A practical example of fl ight phase
programming can be found on page 256).
