L-3’s GH-3100 Electronic Standby Instrument System Selected for T-6B

GRAND RAPIDS, MI, May 7, 2008 – Today, L-3 Communications Avionics Systems (L-3 Avionics) announced that Hawker Beechcraft Corporation has selected its GH-3100 Electronic Standby Instrument System (ESIS) as primary backup instrumentation for the T-6B Texan II military trainer. L-3 Avionics will also be supplying power supplies for the aircraft.

Based on the T-6A, the T-6B features an upgraded avionics package to better train pilots for the modern weapons systems and tactics they will utilize in today’s advanced aircraft. The GH-3100 backs this system up with a digital display layout that coincides with the primary display. This feature reinforces pilot safety by easing the transition from primary to backup instrumentation in an emergency.

“As a standby instrument, the GH-3100 provides backup data in a way that mirrors the T-6B’s advanced avionics systems,” said Larry Riddle, vice president of business development for L-3 Avionics. “In an emergency situation, pilots can receive standby flight information in a familiar layout with the added security of an independent flight data computer. It’s an excellent addition to the aircraft.”

Designed to replace conventional electro-mechanical standby attitude, airspeed and altitude instruments, the solid-state GH-3100 ESIS is capable of providing all three functions, plus heading, slip/skid, navigation data and vertical speed in a single three-inch flat-panel display. The GH-3100 features an integrated air data sensor card with pitot static connections directly to the unit, which eliminates the need for a remote mounted air data computer. An Active Matrix Liquid Crystal Display (AMLCD) provides exceptional readability in direct sunlight as well as dark cockpit environments. The system has the ability to interface with the aircraft’s navigation systems, providing more interfaces and flexibility than any other standby on the market today.

L-3 Avionics Systems has been providing industry-leading avionics technologies to aviation markets for more than 45 years. The company, which is known for bringing cost-effective and advanced technologies to the industry, has recently introduced the SmartDeck® Integrated Flight Controls and Display System, a next-generation avionics suite. Additionally, the company continues to provide a wide array of avionics safety technologies, such as the GH-3000 electronic and J.E.T.® standby instruments, SkyWatch® collision avoidance system, Stormscope® lightning detection system and the IRIS™ Infrared Imaging System.
