STC brings Hawker Avance L3 upgrade capability to Duncan
Operators of the Hawker 800XP aircraft equipped with the Avance L3 system can retain in-flight connectivity once Gogo's newer LTE network is available.
The STC covers the equipment upgrade from Gogo's legacy air-to-ground systems to the newer Avance L3 wi-fi system for operators of the Hawker 800XP.

Duncan Aviation's engineering and certification services unit has developed a supplemental type certificate (STC) covering the equipment upgrade from Gogo Business Aviation's legacy air-to-ground (ATG) systems to the newer Avance L3 wi-fi system for operators of the Hawker 800XP. This STC was completed on a Hawker at Duncan's satellite in Chesterfield, Missouri, at the Spirit of St Louis airport.

This upgrade will allow passengers and crew aboard Hawker aircraft equipped with the Avance L3 system to retain in-flight connectivity once Gogo's newer Long-Term Evolution (LTE) network is available. The LTE network is replacing the existing Gogo Biz network.

"We were pleased to accommodate our customer's wi-fi needs by installing the Avance L3 in his Hawker 800XP," says Ed Reeve, manager of Duncan satellites in St Louis and Nashville, Tennessee. "Now that we have this STC, we are able to provide a reliable in-flight system to our Hawker customers. As long as you're upgrading from one of the Gogo legacy ATG systems originally installed with a Duncan Aviation STC, we can prepare the aircraft and install the Avance L3.”

Downtime for the upgrade is minimal: five business days in most cases. The upgrade entails removing the existing ATG line replaceable unit (LRU) and replacing it with the newer Avance L3 LRU. The antennas installed with the legacy system won't need to be replaced and will provide access to the Gogo LTE network.

Gogo's legacy ATG systems (ATG 8000, 5000, 4000, 2000, and 1000) won't be able to connect to the LTE network. Without an Avance upgrade, aircraft with Gogo's legacy ATG equipment will no longer have in-flight connectivity. To help make the upgrade more affordable, Gogo is offering incentives for customers to upgrade to an Avance system:

- $50,000 rebate for Avance L5 upon service activation

- $25,000 rebate for Avance L3 (Max and Plus only) upon service activation

Planning and scheduling upgrades take time, and there is already a growing demand, so Duncan Aviation recommends customers don't wait to reserve their spot at one of the more than 25 Duncan Aviation satellites located at business aviation airports throughout the country.

In addition to the extensive library of STCs developed by Duncan Aviation for Gogo equipment, STC development is already underway for existing classic ATG-equipped Falcon 2000/2000EX aircraft to Avance L3 coming later this year. The company is also considering additional models of aircraft for STC development.
