Innovative Solutions & Support continues its aggressive certification schedule for RVSM equipment for business aircraft. According to a schedule produced by Dave Martin, vice president of marketing and sales, the Malvern, Pa.-based company is scheduled to obtain STCs for its RVSM air-data display unit (ADDU) on as many as six business airplanes–including the Hawker 700, Sabre 60 and 65, Learjet 31A, King Air 200 and 350–by the end of the year. In addition to developing these RVSM packages, ISS has also been selected by Industrie Aeronautiche Rinaldo Piaggio to retrofit the Italian company’s P.180 Avanti business turboprop with RVSM equipment. Piaggio is scheduled to begin OEM and retrofit installations of the equipment later this year.
