Honeywell and West Star Aviation have received supplemental type certification of an RVSM equipment package for the Learjet 35 and 36. The installations, performed at West Star, Grand Junction, Colo., consist of Honeywell’s AZ-252 advanced air-data computer, AM-250 and BA-250 barometric altimeters and an AL-800 altitude alerter control. Installed price and downtime are $165,000 and about three weeks, respectively. A vast majority of the approximately 400 in-service Learjet 35s, 36s, 35As and 36As will qualify under the STC. Learjets with the Century III Softflite wings and the FC-200 autopilot qualify, as will aircraft modified with Avcon fins or Raisbeck lockers. But so-called straight-wing aircraft and those equipped with the FC-530 autopilot are not included in the current STC.
