Bombardier has gotten a U.S. FAA STC for RVSM operations for Learjet 35 and 36 series aircraft. The certificate is available for aircraft with the Century III Softflite wing configuration, with IS&S Altimeter/ADC and Rosemount Pitot/static probes. The first customer aircraft with full domestic RSVM certification is Cameron-Heinkind. The 35/36 Lears are the eight Bombardier business jets to get RVSM approval, necessary since 1997 for North Atlantic flights. That's a Learjet 31a shown.
