Columbia Avionics Gets STC for Garmin GTN in Citation 500 Series

Columbia Avionics & Aircraft Services obtained FAA STC approval to install Garmin GTN 650 and 750 navcoms in the Cessna 500, 501, 550, 551, S550 and 560. This follows a similar STC that the Columbia, Mo.-based company received in May for the Cessna 650. The touchscreen Garmin GTN navcoms are certified for full autopilot-coupled Waas LPV approaches, including vertical guidance. The STC also covers various combinations of the GTN 650/750, Garmin GTX-33ES mode-S transponders, Garmin GDL-69/A weather data link and a marker beacon receiver.
