L-3 GH-3100 to be Installed by Pro Star Aviation in Sikorsky Aircraft

NBAA ANNUAL CONVENTION, ORLANDO, Fla., October 6, 2008 – L-3 Avionics Systems announced today that Pro Star Aviation has received a Supplemental Type Certificate (STC) to install the GH-3100 Electronic Standby Instrument System (ESIS) in Sikorsky Aircraft Corporation’s S-76A, S-76B, S-76C aircraft. The STC was issued in July.

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. In addition, it 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) also 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.

L-3 Avionics Systems has been helping pilots fly for more than 45 years and provides completely integrated cockpit solutions. The company’s SmartDeck® Integrated Flight Controls and Display System is a glass panel suite that features a revolutionary user interface designed to make flying safer, easier and more enjoyable. In addition to customizing SmartDeck for upcoming aircraft programs, L-3 Avionics 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 and Stormscope® lightning detection system, among others.
