As mentioned before the Piper PA28-181 is probably the best candidate for a GFC500 autopilot. However the GFC500 requires either a Garmin G5, GI275 or a G3X combination as the “brains”. In this particular aircraft the customer choose the GI275 with plans for a future expansion with a third unit for EIS (Engine Indicating System). Includes a Garmin GSB15 USB A-C data loader / charger port. The complete VAC system, mechanical and electrical backup system was removed.
