JetTech received an STC for installation of Garmin’s G600 avionics system in the Cessna Citation 500, 501, 550, 551 and S550. JetTech-approved Garmin dealers are eligible to install the G600 STC in customer aircraft. The JetTech G600 STC retains the jet’s existing RVSM system It also includes JetTech’s proprietary air data interface unit, according to JetTech founder and partner/manager Rob Irwin, allowing the aircraft’s RVSM solution to be displayed on pilot and copilot instruments. The G600 installation replaces the Citation’s original “iron” gyros with lightweight attitude and heading reference systems and includes features such as synthetic vision, Taws, Tcas, radar and XM WX satellite weather. Littleton, Colo.-based JetTech’s next project is an STC for installation of Garmin’s touchscreen GTN 650/750 in the Citation 500 series.
