Duncan Aviation has completed its 550th installation of Gogo Business Aviation's Avance L3 and L5 in-flight connectivity systems. The company’s technicians have performed the installations at its three full-service MROs and 26 Duncan Aviation satellites across a variety of business aircraft models. The use of design data from its 14 Avance supplemental type certificates also enabled other installers to provide an additional 250 operators with the Gogo systems.
“Because of our confidence in the performance and reliability of the Gogo Avance L5 and L3 systems, Duncan Aviation’s engineering and certification services teams have invested and continue to invest in the development of numerous STCs,” said Nate Klenke, Duncan Aviation’s sales manager of modifications and completions in Lincoln, Nebraska.
Avance L5 is a comprehensive Wi-Fi system, offering 4G with faster speeds than the L3. Passengers are able to stream audio and video and transfer large attachments via email. The L3, on the other hand, works best for email and light internet browsing.
Both the L5 and L3 function on Gogo’s air-to-ground low-latency network, ensuring coverage in the contiguous U.S. and parts of Canada and Alaska. The Gogo Avance platform includes an integrated in-flight entertainment media server, known as Gogo Vision 360, which streams movies and TV shows to passengers' devices.
Gogo's ATG network is anticipated to shift to LTE technology by early 2026. Duncan Aviation notes that this will offer enhanced performance for aircraft owners with legacy ATG systems that upgrade to Avance.
Nine of the company’s STCs address the Avance L5, encompassing the Wi-Fi certification and all requisite equipment and antenna installations. The company has attained approval from Transport Canada Civil Aviation (TCCA) for the STCs on several aircraft makes and models, a comprehensive list including Gulfstream, Falcon, and Textron Aviation aircraft, among others.
Duncan Aviation is spearheading STC development for classic ATG-equipped Falcon 2000/2000EX aircraft upgrading to Avance L3, with completion expected later this year. Additionally, the company is exploring more models for STC development.
