Innovative Solutions & Support (IS&S) announced last month it has received FAA TSO approval for a new integrated air-data display system (IADDS), a product that could open the door to RVSM approvals for some older business aircraft. The Exton, Pa.-based company said the air-data product is designed to support “easier installation and certification of legacy business jets” for RVSM compliance, at a lower purchase price. The IADDS is a derivative of IS&S’s air-data display unit installed in thousands of airplanes, but the new product includes technology custom designed for older jets. IS&S has gained RVSM-related STCs for more than 32 business airplane types, and more than 3,000 aircraft are flying with IS&S RVSM avionics, the company said.
