FLARM Anti Collision System
A FLARM unit is fitted, mainly to warn against gliders, which are almost all
equipped with FLARM in Switzerland. The unit is hidden behind the
instrument panel but interfaces with a serial interface into the MapPC.
Traffic is then displayed on the map, along with warning messages and
sounds.

Trutrak Flight Systems “AFS Pilot” Autopilot
The autopilot is a close sibling to the Digiflight II VSGV, also from Trutrak.
The main interfaces for the pilot are the CWS/AP disconnect pushbutton
on the control stick and the EFIS button on the autopilot. Pressing the EFIS
button slaves the autopilot to the commands from the EFIS. Pressing the
CWS/disconnect button shortly while the AP is engaged will disconnect
the autopilot. Pressing the CWS button for more than 2 seconds will turn
on the AP if not already and slave it to the current aircraft track and
vertical rate. The Autopilot is also equipped with an autotrim module,
assuring a trimmed out aircraft upon AP disconnection.
