Duncan Aviation's engineering and certification department has completed a full-equipment STC for installation of the Gogo Business Aviation Avance L5 in-flight internet and Wi-Fi system in Cessna Citation 680 aircraft. This is the seventh STC Duncan Aviation has completed for the system, and it covers the Wi-Fi certification and full equipment and antenna installation required to provide in-flight connectivity to the Gogo Biz 4G network.

This latest STC, completed at the company's Battle Creek, Michigan, facility, adds the Citation 680 to the growing list of aircraft makes/models for which Duncan Aviation has created STCs. That list includes Global Express, XRS, 6000; Global 5000; Challenger CL650, CL605, CL604, CL601-3A and CL601-3R; Challenger 300, 350; Gulfstream GIV, G300, G400; Gulfstream GIV-X, G350, G450; Falcon 900. 900EX (EX, EASy, LX, DX); Falcon 2000 and Falcon 2000EX (EX, EASy, LX, DX, LXS, S).

Duncan STCs have been used for more than 180 installations of the Gogo Avance L5 Wi-Fi system.

Avance L5 connects to the Gogo Biz 4G network, delivering faster speeds and enhanced network capacity, enabling activities such as live streaming video and audio, video conferencing, on-demand movies, personal smartphone use, real-time data for cockpit apps, remote diagnostics and support while in flight.

Demand remains strong for in-flight connectivity options, and Duncan Aviation has installed the Gogo Avance L5 Wi-Fi system in more than 65 aircraft at its three main facilities (Battle Creek, Michigan; Lincoln, Nebraska; and Provo, Utah). Additionally, the technicians at several of the company's 28 avionics satellite shops and workaway stations have also installed these reliable, flexible Wi-Fi systems.

Duncan has applied for and received Transport Canada Civil Aviation (TCCA) approval for all of the models previously mentioned, and the company is awaiting TCCA approval on the Citation 680.
