When paired with the KA 310, the AeroFlight KI 300 replaces the KI 255, KI 256 and the KG 258 with no changes to your instrument panel. KAP 100, 150, 200 and KFC 150, 200, 225 autopilots are natively supported using the AeroFlight KA 310 autopilot interface. The autopilot can be aligned and the air data computer calibrated, both with AeroFlight in the panel, simplifying installation and maintenance. This upgrade lets you save the typical $4000 to overhaul mechanical gyros every 800 hours, and gives all of the information in a primary flight display at a much lower cost.
