DAC International (Booth N3921) has added more autopilots to its approved model list supplemental type certificate (AML-STC) for the GDC31 roll steering converter. These include the ARC300 and ARC800, Century 2000 and KAP 140. The AML-STC currently covers about 700 aircraft makes and models. “The GDC31 interfaces with S-Tec, King, Century and other autopilots and provides our customers with an affordable way to retrofit existing aircraft systems with state-of-the-art capability,” said DAC v-p and general manager Cisco Hernandez.
