Duncan Aviation has long made it easy for customers to discover the power of the Gogo Business Aviation Avance wi-fi system, whether the Avance L3 or Avance L5, and whether upgrading from one of Gogo's classic air-to-ground (ATG) systems or installing an Avance system for the first time. With dozens of STCs for dozens of makes/models, the technicians at any of the more than 30 US satellites can hook operators up with inflight connectivity, entertainment features, 3D moving maps, remote support and a future-ready design.

Duncan is now offering a slot programme that designates capacity at one of its satellite locations for upgrades/installations of Gogo Avance. The programme lets operators select a favourable time slot at the satellite facility of their choice and ensures they can have the installation completed before their older equipment no longer supports connectivity.

Because legacy ATG (8000, 5000, 4000, 2000 and 1000) equipment is unable to connect to Gogo's Long Term Evolution (LTE) network, the older technology won't be supported beyond early 2026 when the network transitions completely to LTE and 5G. Without access to a network, aircraft with legacy ATG equipment will no longer have in-flight connectivity.

For those who like to stay in touch with their office or keep up with important family emails while they are in the air, the Avance L3 offers excellent connectivity for those who need to keep moving but don't want to miss out on what's happening at home or in the office.

Upgrading to the Avance L3 from an ATG system requires a simple box swap; removing the ATG line replacement unit (LRU) and replacing it with the Avance L3 LR, so downtime for the upgrade is five business days in most cases. Duncan's engineering and certification services team has developed STCs covering the equipment upgrade from Gogo's legacy ATG systems to the newer Avance L3 system for the Falcon 2000 and Hawker 800XP aircraft.

For a more robust system that lets users stream video or tune in to video conferences during their flight, the Avance L5 features full streaming capabilities in addition to inflight email, text and phone capabilities.

The team has also developed STCs covering the wi-fi certification and full equipment and antenna installation of the Gogo Avance L5 for the following makes/models:

- Citation 680 and 750

- Challenger 300, 350, 601-3A, 601-3R, 604, 605 and 650

- Global Express, XRS, 5000 and 6000

- Gulfstream G-IV, G300, G400, GIV-X, G350 and G450

- Falcon 900, 900C, and 900EX (EASy, LX, DX)

- Falcon 2000 and 2000EX (EASy, DX, LX, LXS, S)

In addition to FAA approval, all Duncan STCs for the Avance L3 and L5 have Transport Canada approval.
