Decision taken to install full Garmin suite. Autopilot servos (GSA28) for pitch and roll already purchased together with heated pitot with AOA sensor (GAP26) Intention to install two flight display G3X 10,6" (GDU460) with one ADHARS (GSU25) and GMU11 Magnetometer, Engine Monitor System (GEA24 with 6 cyl lycoming kit) and G5 HSI Display with built in ADHARS as backup. I plan to install two certified COM/NAV, Certfified GPS and ADSB IN/OUT transponder. I am currently considering to installa one GTN650XI (GPS, COM NAV) with one GNC255 (COM/NAV) and remote transponder (GTX45R). As a possible alternative 2 GNC255 COM/NAV and the GTX345 or GTX374 Transponder/GPS. In addition I plan to install the autopilot panel (GMC305 or GMC507), the GMA245 Audiopanel and the GAD27 interface (Trim, flap controller) and the GAD29 ARINC if necessary. Logical scheme of the two systems are depicted in the attached slides. The schemes includes for reference the autopilot servos (GSA28) , trim servos (Ray Allen), flap actuator and additional devices like internal lights, cooling fans, ELT panel, USB ports, CO Detector and Oxygen System. These will be detailed together with all the other power appliances in separate charts
