Autopilot Control / Flight Director 
Note: There is a separate AF-Pilot Installation Manual found on the AFS website. 
 Current AP Mode 
Autopilot Control 
For the autopilot to follow the EFIS commands you will need an autopilot that is capable of GPSS and 
GPSV ARINC steering commands. You will also need to have the optional AF-ARINC module connected 
to the EFIS and properly configured. 
The following Autopilots will work with the EFIS: 
ADVANCED Pilot 
TruTrak Digiflight II VSGV 
TruTrak Sorcerer 
Trio Pro Pilot 
The autopilot and flight director are very closely connected and are controlled from the same source. If 
your aircraft has our ADVANCED Pilot autopilot it supports GPSS (GPS steering) and GPSV (GPS 
vertical steering) and the aircraft should closely follow the flight director when the autopilot is in EFIS 
Mode. 
ADVANCED Pilot Autopilot Controls 
The AF-Pilot Autopilot is manufactured by TruTrak, it is very similar to the DigiFlight II VSGV and has all 
of the same wiring, configuration, and setup. You must have the Primary Serial Input Pin on the AP 
connected to your GPS along with the ARINC A and B lines connected to the AF-ARINC module. The 
autopilot should be installed in accordance with the AF-Pilot Installation Manual. 
Your AF-Pilot or Digiflight II Autopilot must have the latest software that accepts vertical speed 
commands.
