Gulfstream Aerospace announced it has earned approval from the FAA to upgrade Gulfstream GIV and GV aircraft with Future Air Navigation System (FANS) over Iridium (FOI) using the TrueNorth Simphonē FANS 1/A+ Data Link Unit (DLU). Once installed, the stand-alone unit enables data connectivity over the Iridium satellite communications (SATCOM) network, allowing for FANS communication in remote coverage areas.

“This is a cost-effective, compact and lightweight FANS 1/A+ data link solution that enhances aircraft operations and safety in congested airspace by providing Iridium connectivity and the reliable, truly worldwide communication that comes with that network,” said Derek Zimmerman, president, Gulfstream Product Support. “This system operates as the sole data link service on aircraft without FANS 1/A+-compatible Inmarsat SATCOM installed. On aircraft already fitted with FANS 1/A+-compatible Inmarsat SATCOM, the system functions as a backup data link solution, greatly increasing dispatch reliability because of the redundancy provided.”

Operational mandates require FANS 1/A+ for the most wind-efficient North Atlantic Ocean (NAT) flight tracks. After Jan. 30, 2020, aircraft without FANS 1/A+ will not be permitted to operate in NAT region above 28,000 feet/8,534 meters.
