Duncan completes Falcon 2000 STC for Avance L3 upgrades
Completed on a Falcon 2000 at Duncan's satellite in Chesterfield, Missouri, the STC received FAA approval in late November 2023 and allows Avance L3-equipped Falcon 2000 owners to access Gogo's LTE network.

Duncan Aviation's engineering and certification services department has developed an STC covering the equipment upgrade from Gogo's legacy air-to-ground systems to the newer Avance L3 wi-fi system for the Falcon 2000.

This upgrade allows passengers and crew aboard Falcon 2000 aircraft equipped with the Avance L3 to retain in-flight connectivity by accessing the newer Gogo Biz Long-Term Evolution (LTE) network, which will eventually replace Gogo's existing Evolution-Data Optimised (EV-DO) network.

Downtime for the upgrade is minimal: five business days in most cases. The upgrade entails removing the older legacy ATG system and replacing it with the newer Avance L3 system. In most instances, the existing ATG antennas already installed will provide access to the Gogo LTE network, simplifying the installation.

Because legacy ATG (8000, 5000, 4000, 2000 and 1000) equipment will not be able to connect to the LTE network, the older technology will not be supported beyond early 2026 when the network transitions completely from EV-DO to LTE and 5G. Without access to a network, aircraft with legacy ATG equipment will no longer have in-flight connectivity.

Planning and scheduling upgrades takes time and there is already a growing demand for hangar space, so Duncan Aviation advises customers reserve their slots before the transition.
