The Aspen Avionics Evolution primary flight display system received EASA STCs for installation in the Pilatus PC-6 and Beechcraft Bonanza 33, 35 and 36 series. The PC-6 STC was developed by Ruag Schweiz of Switzerland and the Bonanza STC by Germany’s Avionik Straubing. These STCs incorporate the most recent Evolution software, which received ETSO certification in April, according to Aspen. The new ETSO-approved capabilities include the Evolution multifunction display, EA100 autopilot adapter and approvals for installation in certain helicopters and Class III aircraft (weighing more than 6,000 pounds). Aspen also announced that two customers have installed the Evolution displays in their Aero Vodochody L-39 jets.
