World First - Telestra 4 Level D Certification for JAA and FAA


May 1, 2009

Advanced Simulation Technology, inc. (ASTi, Herndon, VA) is pleased to announce that a Telestra 4 sound and communications system, fitted to a 737-800 simulator, was recently certified to meet Level D standards for both the JAA STD 1A amendment 3, and FAA Part 60. This simulator is the world's first certified to both standards on one device, and represents the state-of-the-art in full flight simulators. The single Telestra 4 processor provides both aural cue sounds for the aircraft through all phases of flight, and communications system audio for both crew and instructors.

The aural cue simulation utilized the latest soundfield reconstruction capabilities of the ASTi ACE software toolkit to provide full immersive 3D sound directionality, and meet the requirement to match objective spectral analysis over the frequency range 50Hz to 16kHz within the ±5dB tolerances defined in both FAA and JAA standards.

Communications within the cockpit includes replication of the aircraft intercom buses, radio transceivers, navigation receivers, and all cockpit warning and caution alerts, including TCAS voice messages. The instructor has the ability to monitor all crew communications and provide role-play capability for all external radio entities, with support from a fully automatic ATIS system.

ASTi is also pleased to report that a 737NG simulator installed in Europe, fitted with an ASTi Telestra system providing Level D sound and communications, recently passed 7000 hours operational use with 99.6% simulator reliability. ASTi is proud to be associated with such an outstanding reliability record for such a challenging and complex training device.

ASTi currently has five Level D systems in-work for commercial simulators (FAA Part 60/JAA Std 1A amendment 3), and nineteen Level D systems for the U.S. Air Force (FAA AC120-40B/C), making ASTi the leading supplier of COTS Level D solutions to the simulation and training industry.
