GULFSTREAM IS FIRST TO RECEIVE APPROVAL FOR FANS 1/A DATA LINK OPERATION ON LARGE-CABIN BUSINESS AIRCRAFT

System Enhances Aircraft Communication And Navigation

SAVANNAH, Ga., June 8, 2010 - Gulfstream Aerospace Corp.’s Flight Operations department has received Federal Aviation Administration (FAA) approval to use the Future Air Navigation System (FANS) 1/A data link on its G450 aircraft. Gulfstream is the first large-cabin purpose-built business-jet manufacturer to receive such approval.

FANS was developed to address air-traffic control’s ability to handle a dramatic increase in aircraft traffic. The system uses automation and satellite-based navigation to improve aviation communication, navigation, surveillance and traffic management.

The ability to use FANS 1/A applies to G450 aircraft equipped with the enhanced navigation package, which is available as part of Certification Foxtrot for PlaneViewTM, the signature Gulfstream flight deck featuring Honeywell Primus Epic avionics. The enhanced package adds Controller-Pilot Data Link Communication (CPDLC) to Automatic Dependent Surveillance – Contract (ADS-C), completing the aircraft’s FANS 1/A capability.

"This approval reflects the tremendous effort we’ve made toward preparing Gulfstream aircraft for the next generation of air navigation," said Pres Henne, senior vice president, Programs, Engineering and Test, Gulfstream. "Being able to offer ADS-C and CPDLC to our operators is important because they provide improved communications and operational efficiency. Our operators value that and we do, too."

CPDLC/ADS-C provides flight crews with direct communication to oceanic and remote-area air- traffic controllers. It enhances safety because it automatically reports when an aircraft deviates from its cleared altitude and route. It also provides meteorological data from the aircraft’s sensors.

Crews using the data link log on to the air-traffic system computer, which allows it to exchange information with ground-based computers. Those computers automatically transfer responsibility for the aircraft to the next region’s air-traffic system as the aircraft travels along its route. This eliminates the need for crews to use radio operators and high-frequency radios to request clearances and provide position reports.

ADS-C allows an air-traffic controller to initiate the tracking of an aircraft’s position from the ground using information sent at predetermined intervals from the jet’s onboard sensors.

Certification Foxtrot’s enhanced navigation package offers improved navigational performance, increased efficiency and greater access through an upgraded Flight Management System (FMS). In addition to FANS capability, the upgrade includes redundant electronic terminal charts for paperless dispatch, upgraded Inertial Reference Units (IRUs) to enable High Step 1, Wide Area Augmentation System-Localizer Performance with Vertical Guidance (WAAS-LPV), and Required Navigation Performance (RNP) below 0.3.
