Garmin dealer Columbia Avionics & Aircraft Services has added STC approval for installing Garmin GTN series GPS/comm navigators and ADS-B OUT in the Cessna Citation Excel/XLS (560XL). This STC comes in addition to earlier approvals for these products in the Citation 500, 501, 550, 551, S550, 560 and 650, and it can include combinations of the GTNs, Garmin GTX mode-S transponders, GDL-69/A weather datalink and marker beacon receiver.

In the 560XL installation, the GTN-750 and GTN-650 provide “full autopilot-coupled WAAS LPV approaches including vertical guidance,” according to Columbia. 

Columbia also announced that it received FAA STC approval for an ADS-B OUT package, using Garmin GTS-8000 TCAS II and GTX-3000 mode-S transponders in the Citation SII (S550). This solution features the GTN series navigator as the required position source for ADS-B OUT. Columbia expects to receive FAA approval for this package in the Citation 500, 550, 560 and 560XL “later this year."
