Gogo Business Aviation’s Avance L5 air-to-ground connectivity system will be available as an upgrade to owners of Cessna Citation X+, Sovereign+, and Latitude business jets following receipt by Textron Aviation of a new STC, the manufacturer announced Tuesday at NBAA-BACE. Avance L5 offers faster inflight connectivity speeds and an enhanced network capacity.

“Optimizing connectivity across a range of Textron Aviation products is one more way we can enhance the ownership experience,” said Textron Aviation senior v-p of global customer support Kriya Shortt. “For many of our customers, the ability to connect twice as many devices and join a video conference call in flight turns travel time into productive office hours.”

The STC expands the Wichita airframer’s approved model list STC to include eight Citation models. Earlier this year, it announced STCs for Avance L5 for the Citation X, Sovereign, and XL/XLS/XLS+. The company has since done nearly 150 Avance system upgrades for Citation customers.
