Southeast Aerospace (SEA) has partnered with China Trancomm, Cobham, Inmarsat and Delta G Design to certify the Cobham Aviator 300 system, fitted with Inmarsat’s SwiftBroadband Safety capability for Airline Operational Communications (AOC) messaging, on Shenzhen Airlines’ Boeing 737-800 fleet.

This system will make Shenzhen Airlines compliant with the Civil Aviation Authority of China (CAAC)’s four-minute mandate.

The mandate, more formally known as the Satellite Communications Implementation Plan for Airline Operations Control, requires airlines to operate and control voice communications independent of air traffic control within four minutes.

The system will also interface to the airplane’s existing Aircraft Communications Addressing and Reporting System (ACARS), allowing the flight deck data messages to be carried over Inmarsat SwiftBroadband.

SBB Safety enables voice and Aircraft Communications Addressing and ACARS/Future Air Navigation Systems (FANS) data transmissions when aircraft are flying over oceans, improving safety and efficiency in oceanic airspace.

The system enables the fast and efficient transfer of data messages using Inmarsat’s SwiftBroadband connectivity via a secure, dedicated “pipe” to the cockpit. The ACARS message is encapsulated into an IP “message”, which is then stripped out on the ground before being fed into the ACARS data network.

The combination of IP and ACARS data pipes allows network integration with a portfolio of data housing and transmitting components on the aircraft such as cockpit, Electronic Flight Bag devices (EFB), onboard maintenance computers and devices used by the crew to service passengers.

SEA engineers have completed the aircraft survey in Shenzhen, China, and development of the FAA Supplemental Type Certificate (STC) and CAAC Validation of Supplemental Type Certificate (VSTC) is well under way.

SEA is based in Melbourne, Florida, USA and produces structural and installation schematics for modification programmes on aircraft such as Airbus, Bell, Boeing, Bombardier, Dassault, Eurocopter, Gulfstream, and Sikorsky.
