Fly Connected: Go With Gogo Avance L5


One of the go-to, air-to-ground connectivity options Duncan Aviation recommends to its customers is the Gogo Business Aviation AVANCE L5 internet and Wi-Fi system. There is no longer a reason to feel a loss of productivity when systems like the Gogo AVANCE L5 offer reliable connections, speed, and ease-of-use. Conversely, if you’re looking to escape the demands of the office for a few hours, the system is equally as dependable for connecting to a variety of entertainment sources.

For a limited time, Duncan Aviation is extending the 3-month IFE trial offered by Gogo for 12 months of free, unlimited access to Gogo Text and Talk and Gogo Vision subscriptions to operators who install the Gogo AVANCE L5 hardware that connects to the Gogo Biz 4G network at any of Duncan Aviation’s full-service facilities or Satellites.

Gogo Text & Talk lets an aircraft’s crew and passengers use their personal smartphones and devices to call and text in the air just as they do on the ground. Gogo Vision lets passengers use their own devices to enjoy blockbuster movies, hit television shows, popular magazines, flight maps (which include an incredible 3D moving map), and more during their flights.

Whether the inflight connections are used for business or entertainment, the AVANCE L5 taps into a reliable, high-speed 4G network so passengers can remain engaged throughout the flight.

“We’re excited to offer this extended trial period for the outstanding IFE products available on the Gogo AVANCE platform,” says Modifications Sales Manager Nate Klenke. “Offering this extension is our way of showing appreciation to the owners and operators who continue to trust Duncan Aviation with their connectivity upgrades.”

In 2017, Duncan Aviation’s full-service facility in Battle Creek, Michigan, installed its first Gogo Business Aviation AVANCE L5 internet and Wi-Fi system. Since then, the Duncan Aviation Engineering & Certification team has completed 9 STCs (Supplemental Type Certificates), covering the equipment and antenna and the complete installation of the AVANCE L5 system into more than 30 aircraft makes and models. As of early April 2021, the Duncan Aviation avionics install teams throughout the company have used those STCs to install the Gogo AVANCE L5 internet and Wi-Fi systems in 250 airplanes.

Duncan Aviation’s STCs are available for numerous aircraft makes/models including the following:

  • Citation 680
  • Citation 750
  • Global Express, XRS, 6000
  • Global 5000
  • Challenger CL-650, CL-605, CL-604, CL-601-3A and CL-601-3R
  • Challenger 300, 350
  • Gulfstream GIV, G300, G400
  • Gulfstream GIV-X, G350, G450
  • Falcon 900
  • Falcon 900EX (EX, EASy, LX, DX)
  • Falcon 2000
  • Falcon 2000EX (EX, EASy, LX, DX, LXS, S)

Additionally, Duncan Aviation pursued and received approval from TCCA (Transport Canada Civil Aviation) and EASA (European Union Aviation Safety Agency) for all of its STCs for the AVANCE L5.

Duncan Aviation can install the Gogo AVANCE L5 system at its three main facilities (Battle Creek; Lincoln, Nebraska; and Provo, Utah) and at most of the company’s Satellites.

Terrestrial Connectivity Options Abound

In June 2020, Duncan Aviation announced a cooperative venture with Gogo Business Aviation to provide new installation options for the Gogo AVANCE L3 and the Gogo AVANCE SCS (Smart Cabin System). Duncan Aviation’s Engineering & Certification Services teams updated three existing STCs for the Gogo AVANCE L5 Wi-Fi system to cover the installation of the AVANCE L3 Wi-Fi system or a standalone SCS on the following aircraft:

  • Gulfstream GIV and GIV-X
  • Bombardier Challenger 300 and 350
  • Bombardier Challenger CL-650, CL-605, CL-604, CL-601-3A and CL-601-3R

The amended STCs include the installation of the Single Air Card LRU (Line Replacement Unit) and mounting tray and cover all other existing architecture for the AVANCE L3, including the Wi-Fi and terrestrial modem (cellular) antennas. The amended STCs will also cover design changes for the installation of the Gogo AVANCE SCS.

AVANCE L3 has a lightweight, small form factor compared to other inflight connectivity systems with similar capabilities and is more affordable. AVANCE L3 allows users to customize their inflight experience based on their unique needs, and its software-based scalable capabilities make it an ideal option for smaller aircraft including turboprops and light jets.

Although Duncan Aviation is not extending the free, 3-month period for the Gogo Text & Talk and Gogo Vision with the AVANCE SCS or L3 Wi-Fi system, both subscription services are available.

AVANCE SCS is a highly integrated smart cabin system that gives passengers a single interface for whatever a user wants to do: browse the Internet, make and receive phone calls, access the CMS (Cabin Management System), or access moving maps, movies, TV, and news via Gogo Vision. Because it’s compact and lightweight, SCS can be installed on virtually any sized business aircraft, including aircraft that fly outside the US because it works across ATG and satellite systems.


If you need a reminder of what flying is like when you don’t have access to a decent Wi-Fi system supported by a reliable 4G network, watch this poor, hapless soul who is unable to appreciate the comfort of his long flight as he is overcome by boredom!
