ETC Announces that the ATFS-400 "Phoenix" Authentic Tactical Flight Simulator has been Commissioned at NASTAR Center

Southampton, Pa, September 25, 2008- Environmental Tectonics Corporation (AMEX: ETC) ("ETC" or the "Company") today announced the commissioning of the ATFS-400 Phoenix at its National AeroSpace Training and Research Center (NASTAR Center). The ATFS-400 will be featured by ETC at the Defendory Conference in Athens, Greece.

The ATFS-400™ Phoenix is a high fidelity, interactive, virtual tactical air combat maneuvering flight simulator that is integrated into a state-of-the-art high performance "flyable" centrifuge motion platform. Its revolutionary design enables it to authentically simulate the dynamic performance, mission systems and interactive elements of a specific type and model of aircraft in tactical environments. The ATFS-400™ Phoenix precisely replicates real world aircraft and threat dynamics. Pilot inputs are processed by the aeromodel to simultaneously drive the virtual (sight and sound) cues and command the multi-axis centrifuge to correctly produce the sustained G-forces that the pilot would experience while flying the actual aircraft. The ATFS-400™ Phoenix authentically simulates the flight dynamics providing the virtual cues, visual fidelity, and physical stresses experienced during combat maneuvers correlated to the specific tactical aircraft. In short, the ATFS-400™ Phoenix is the new technology in high performance aircraft simulation, providing realistic combat air training.

The ATFS-400™ Phoenix design integrates four unique proprietary systems developed by ETC over nearly three decades: the High Performance Human Centrifuge motion platform; the G-POINTING™ motion control system to create authentic sustained G cuing based on the pilot's flight control inputs; the Virtual Battlespace to support multi-aircraft training operations with programmable targets and threats; and the interchangeable Cockpit Module to support high fidelity, aircraft specific training.

ETC's Cockpit Modules provide for unprecedented training flexibility. The Cockpit Module allows tactical pilots to train in their specific weapons system. Cockpit Modules are easily interchangeable in the ATFS-400™ Phoenix, by two people in about one hour.

Each Cockpit Module can function as a stand-alone operational flight simulator when not installed in the ATFS-400™ Phoenix. The Cockpit Module size, weight and ruggedness make it an ideal expeditionary trainer that can deploy to combat zones with fighting units for in-theater training and mission rehearsal. Each Cockpit Module is HLA compatible so it can be data linked with each other, with the ATFS-400™ Phoenix and with existing HLA compatible simulators. Whether as standalone, stationary operational flight simulator, part of a network of data linked Cockpit Modules operating in a common battlespace, or part of the ATFS-400™ Phoenix motion-based, high-G tactical flight simulator system, Cockpit Modules are the solution to your flight training challenges.
