Duncan Aviation has recently completed its 550th installation of Gogo Business Aviation's Avance L3 and L5 in-flight connectivity systems. In addition to the 550 installations completed by technicians at Duncan's three full-service MROs and 26 satellites, design data from the company's 14 Avance supplemental type certificates (STCs) has been used by other installers to provide another 250 operators with a Gogo Avance system.

“Duncan Aviation has had a long and productive relationship with Gogo Business Aviation, which provides a significant benefit to our mutual customers,” says Lincoln, Nebraska sales manager of modifications and completions Nate Klenke. “Because of our confidence in the performance and reliability of the Gogo Avance L5 and L3 systems, our engineering and certification services teams have invested and continue to invest in the development of numerous STCs. We are pleased to have installed these connectivity solutions in so many customer aircraft.”

Gogo Avance L5 is a complete wi-fi system that delivers a 4G experience, letting cabin passengers take advantage of greater network capabilities with speeds up to three times faster than an L3. The L5 offers enhanced connectivity applications, which means passengers will enjoy an improved online user experience while in flight with the ability to stream audio and video and send email with large attachments.

The Avance L3 is designed for airframes of all types and sizes, but is ideal for email and lite internet browsing. The system is scalable with several configurations available as well as a modem and router.

The Avance L5 and L3 operate on Gogo's ATG low-latency network with coverage in the contiguous US and portions of Canada and Alaska. The Gogo Avance platform gives those on board the ability to text and make phone calls and comes with an integrated inflight entertainment (IFE) media server, Gogo Vision 360, featuring streaming movies and television programmes to the personal devices of those on board.

Gogo's licensed air-to-ground network is expected to be transitioned to LTE technology by early 2026. Aircraft with Gogo's legacy ATG systems (ATG 1000, 2000, 4000 and 5000) that upgrade to Avance will see an immediate improvement in performance with an additional boost when the network transition to LTE is complete.

“The fact that Duncan Aviation has installed 550 Gogo systems on so many different airframes over the years says everything about our partnership,” says Gogo VP of aftermarket sales David Salvador. “We celebrate the more than 25 years we have been working together with the team, connecting the business aviation community.”

Duncan Aviation's nine Avance L5 STCs cover the wi-fi certification and full equipment and antenna installation required to provide in-flight connectivity. All of the STCs that the Duncan Aviation teams have completed for Gogo Business Aviation system are available throughout the US and can be installed at any of its three full-service facilities and at many of its satellite shops and workaways. Additionally, Duncan Aviation has sought and received approval from Transport Canada Civil Aviation (TCCA) for the STCs on a variety of makes/models:

Duncan Aviation is considering additional models for STC development.
