ENVIRONMENTAL TECTONICS CORPORATION - Press Release
ETC Announces Contract Award for a GYROLAB GL-1500, Advanced Spatial Disorientation Trainer
July 25, 2005
SOUTHAMPTON, Pa., July 25, 2005 -- Environmental Tectonics Corporation (Amex: ETC) ("ETC" or the "Company") today announced receipt of a contract from a Middle Eastern customer for its Advanced Spatial Disorientation Trainer, the GYROLAB GL-1500. The GYROLAB GL-1500 will be used to train high performance aircraft pilots to deal with the problems of Spatial Disorientation, loss of Situational Awareness, and recovery from unusual flight attitudes or conditions that can occur during maneuvering flight. The value of the contract is approximately $4.0 million.

The GYROLAB GL-1500 combines the latest available simulation technology, including G-Point™. ETC's proprietary G-Point™ system precisely transforms the simulated aircraft dynamics generated by the pilot's flight control inputs into motion commands to vary the planetary speed and the position of the multi-axis gondola. This technology allows the GL-1500 to replicate the motions and G forces experienced in actual aircraft maneuvering flight. The GL-1500 features a motion system that generates simultaneous ± 360 degree motion in pitch, roll, yaw, and planetary; real world out-the-window visuals; realistic engine and flight sounds; a detailed aircraft cockpit with closed loop flight controls; and a high fidelity aeromodel. Dynamic Force Feedback flight control loading is also included to provide the pilot with the most realistic flight experience short of actually flying the aircraft. The GYROLAB GL-1500's primary configuration is of a high performance fixed wing aircraft. However, its configuration can be changed to a helicopter in less than 5 minutes.

Since all axes of motion can be used simultaneously, the GYROLAB GL-1500 can accurately reproduce the motion cues that cause pilots to mistake their aircraft position and motion with respect to the earth's surface. This error is called Spatial Disorientation. The GYROLAB GL-1500 features 20 fixed wing training profiles and 8 helicopter training profiles that are flight realistic and fully automated. These training profiles provide pilots with the means to recognize and avoid or successfully recover from Spatial Disorientation. ETC's proprietary Interactive Profile Editor allows instructors to create their own training profiles, thereby making the GYROLAB GL-1500 a trainer that can keep pace with changing training requirements throughout its life cycle.

The GYROLAB GL-1500 can also train pilots in high-risk flight maneuvers including aircraft upset recovery, spins, and stalls…all in a safe, controlled learning environment. The GYROLAB GL-1500's Instrument and Navigation system uses real world navigation data that is synchronized with its real world visual database to provide the most effective training for instrument pilots. The GYROLAB GL-1500 includes a medical monitoring system to support research activities and also to conduct motion sickness desensitization and mishap recreation. The medical monitoring system can be tailored to the customer's research needs.

Spatial Disorientation remains a largely unsolved and serious problem for air forces all over the world. Worldwide, losses due to spatial disorientation result in hundreds of millions of dollars and many lives each year. In the USA alone, it costs on average more than $400 million in destroyed aircraft and numerous pilot lives each year. ETC's GYROLAB GL-1500 with its unique capabilities is the only trainer that can crate the full fidelity learning environment where pilots can master the skills to successfully cope with Spatial Disorientation

William F. Mitchell, ETC's President and Chairman, stated, "The GYROLAB GL-1500 sets the benchmark in high fidelity simulation and aeromedical training, and it embodies our latest technology. By training pilots to avoid spatial disorientation, the GL-1500 preserves aircraft and pilots' lives."



ETC designs, develops, installs and maintains aircrew training systems, public entertainment systems, process simulation systems (sterilization and environmental), clinical hyperbaric systems, environmental testing and simulation systems, and related products for domestic and international customers.
