Duncan Aviation STC for Gogo Avance L3 upgrades on Hawker aircraft


An STC has been developed by Duncan Aviation’s Engineering & Certification Services to cover the equipment upgrade from Gogo Business Aviation’s legacy air-to-ground (ATG) systems to the newer Avance L3 wi-fi system for Hawker 800XP operators.

This STC was completed on a Hawker at Duncan Aviation’s satellite facility in Chesterfield, Missouri, at the Spirit of St Louis Airport.

This upgrade will allow passengers and crew on board Hawker aircraft equipped with the Avance L3 system to retain inflight 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,” said Ed Reeve, manager of Duncan Aviation’s satellites in St Louis, Missouri, and Nashville, Tennessee. “Now that we have this STC, we are able to provide a reliable inflight 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.”

Duncan Aviation said downtime for the upgrade is 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 inflight connectivity. To help make the upgrade more affordable, Gogo is offering incentives for customers to upgrade to an Avance system: a US$50,000 rebate for Avance L5 upon service activation; and a US$25,000 rebate for Avance L3 (Max and Plus only) upon service activation.

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

Duncan Aviation is considering additional models for STC development to assist operators with the transition from Gogo’s legacy ATG systems to its Avance platform, to be performed at one of Duncan Aviation’s three full-service facilities and more than 25 satellites.
