First there were none, now suddenly there are four companies here that announced their intention to develop a reduced vertical separation minimum (RVSM) STC package for the Learjet 20 series. All four companies propose to achieve the approval using the airplane’s original JET autopilot, and all four estimate the price to be under $150,000.  

Joining Avcon Industries and Spirit Wing (see NBAA Convention  News, Wednesday, September 11, page 12) is LSJC (Booth No. 4871), a one-year-old engineering and certification consulting company based in Wichita and comprised of ex-Bombardier employees, and Bizjet International of Tulsa, Okla.
