GULFSTREAM OFFERS UPGRADE TO AIRCRAFT
INTRUSION-WARNING SYSTEM

Securaplane’s PreFlite™ Provides Enhanced Levels Of Security For Operators

SAVANNAH, Ga., April 15, 2010 - Gulfstream Aerospace Corp. now offers an upgrade option for operators who want enhanced levels of security for their large-cabin aircraft. The Securaplane Technologies PreFlite™ System expands on its existing technology to provide worldwide, real-time event notification and remote system control/interrogation via a GSM-connected cell phone or land line.

The system enhancement also allows:

• A quick and easy upgrade from Systems 500 and 450 with minimal downtime
• New, more accurate, radar-based wheel-well sensors
• Enhanced intrusion communications through system alerts via calls or texts to the aircraft operator’s cell phone
• The ability to arm, disarm and check status from any phone

The PreFlite System uses metal reed relay switches to monitor door/panel status and range-controlled radar (RCR) detectors to monitor wheel wells. Each system includes a control display unit (CDU) that provides read-out capability of all intrusion data and a list of all monitor points.

A digital alarm indicator, in the form of a miniature CDU, is mounted behind a small panel such as the oxygen door, where it can be accessed from outside the aircraft. It can arm and disarm the system, and its LED display shows system status and violations.

More than 1,100 aircraft security systems made by Securaplane, a Tucson, Ariz.-based company, have been installed in aircraft ranging from turboprops to business jets. For more than a decade, Gulfstream has certified and installed Securaplane’s legacy aircraft security systems on several large-cabin airplanes, with some being a standard option.
