Stevens Finalizes Gogo Galileo HDX STC for King Air

Stevens Aerospace and Defense Systems has completed all work and flight testing for its FAA supplemental type certificate (STC) covering the Gogo Galileo HDX global high-speed internet system for Beechcraft King Air 200s and 300s. FAA issuance of the STC is expected later this month.

The initial certification will include multiple avionics configurations and integrates onboard Wi-Fi activation for simplified installation. Stevens’ FAA-approved STC will also include validations with EASA, Canada’s TCAA, and Brazil’s ANAC, and be available for sale either with installation or as a standalone authorization.

Developed in partnership with Gogo Business Aviation and Peregrine Aerospace, the installation brings satellite-based global broadband to King Air operators using Eutelsat-OneWeb’s low-earth-orbit network. The Galileo HDX antenna delivers download speeds up to 60 Mbps and upload speeds up to 11 Mbps worldwide. During Stevens’ final flight tests, six users streamed heavy content simultaneously while using only half of the system’s capacity.

The new system can also be added to existing Gogo Avance platforms—including L3, L5, LX5, and SCS—offering connectivity beyond North America. Additional Avance capabilities, such as over-the-air software updates, remote diagnostics, and high-speed ground connectivity, extend functionality beyond traditional air-to-ground systems.

“As the leading King Air MRO, we are excited to bring this new technology from a long-standing aviation connectivity provider to our King Air customers around the world,” said Stevens director of avionics Rob Reed.
