Cessna has placed an order with avionics maker Innovative Solutions & Support for an undisclosed number of flat-panel cockpit displays that will be offered as part of an upgrade program for operators of older Citations. The installations will be available at any of the 34 Cessna Service Centers (factory and authorized) worldwide. About 4,000 Citations are candidates for the retrofit. Jim Riley, IS&S’s CFO, said an internal survey conducted by his company showed that around 2,500 Citations are “long overdue” for flight-deck makeovers. The deal is a huge potential source of revenue for the Exton, Pa. company as it seeks to get its fledgling cockpit displays business off the ground. IS&S holds an STC for the retrofit in the Pilatus PC-12 and is installing glass cockpits in Boeing 767s for cargo airline ABX Air, but this is its first such deal involving an aircraft manufacturer. The company is best known for its line of RVSM and air-data equipment.
