Swiftbroadband is going to be the ticket As part of the modification process Flying Colours will integrate a customized Inmarsat Cobham Aviator 700 inflight connectivity system. This will enable flexible communications and connectivity via the Inmarsat SwiftBroadband network that can be adapted for each aircraft mission.
The Aviator 700 is a compact design combining a High Gain Antenna (HGA) to offer a multitude of capabilities to pilot and crew including the option of voice dialling from the cockpit MCDUs. It can also support FANS 1/A (Future Air Navigation System), CPDLC (Controller Pilot Data Link Communications) and voice safety service operations via the system’s cockpit data and H+ voice channels.
