Avidyne Corp., Lincoln, Mass., and S-TEC Corp., Mineral Wells, Texas, received a supplemental type certificate from the FAA for installation of the Alliant Integrated Flight Deck on Beechcraft King Air E90- and C90-series turboprop aircraft. The installation, Avidyne said, enables owners of King Air aircraft to update their systems with situational awareness and safety tools at a fraction of the cost of a new aircraft. The installation of the Alliant Integrated Flight Deck into Standridge Color’s E90 for the STC was performed at S-TEC’s facility in Mineral Wells, Texas. Future installations may be performed at authorized Alliant dealer locations. The Alliant installation and flight tests for the 90-series STC were completed on a 1976 E90 is owned and operated by Standridge Color Corp., a Social Circle, Ga.-based manufacturer of colorants for the plastics industry. The standard Alliant Integrated Flight Deck package includes dual-redundant Avidyne EXP5000 10.4” primary flight displays, an Avidyne EX500 multi-function display, the S-TEC IntelliFlight 2100 digital autopilot, Mid-Continent two-inch standby instruments and interfaces to most popular traffic, terrain, lightning, radar and radar altimeter systems. The Alliant Integrated Flight Deck is the first large-glass and autopilot retrofit Integrated Flight Deck to be certified and delivered on light general aviation aircraft.
