ENVIRONMENTAL TECTONICS CORPORATION - Press Release
ETC Announces the Acceptance and Commissioning By the Metropolitan Airports Commission of ETC's Driver Training Simulator
August 9, 2004
SOUTHAMPTON, Pa., Aug. 9 /PRNewswire-FirstCall/ -- Environmental Tectonics Corporation (Amex: ETC) has achieved final acceptance of its Drivers Training Simulator by the Metropolitan Airports Commission (MAC).

Located in the Airside Operations Training Facility at Minneapolis-St. Paul International Airport (MSP), the Drivers Training Simulator includes a high-fidelity virtual database of the entire MSP complex, with a level of detail that is unparalleled -- down to exact replications of every runway light, sign, and marking, all in the correct size and location. In addition to the virtual environment, ETC provides typical airport activity using moving models, with aircraft at gates, taxiing, taking off and landing, as well as all types of service vehicles and personnel found at an active airport.

ETC uses an actual Oshkosh Truck Corporation T-3000 Aircraft Rescue and Fire Fighting (ARFF) Vehicle Cab as the driver station for its simulators, which incorporates validated, accurate vehicle dynamics for an instructor- selectable range of vehicles. This allows training for drivers of fire trucks, ambulances, police vehicles, snow removal equipment, operations vehicles, baggage tugs, service trucks, etc., in a real-time, interactive, environment.

The MAC will use their Drivers Training Simulator to provide airport personnel with training in runway incursion avoidance, airport fire and emergency response, airport orientation and familiarization, Airside Operations Area (AOA) driving procedures, aircraft servicing, and snow removal procedures.

With the MAC simulator now in operation, the Driving Simulator at Chicago O'Hare nearing completion, and the Metropolitan Nashville Airport Authority Driving Simulator scheduled for completion in January 2005, ETC is solidifying its place as the leading supplier of Airport Driving Simulators.

ETC is also the creator of the Advanced Disaster Management Simulator (ADMS(TM)). The ADMS(TM) is the only virtual reality-based simulator available today that allows the realistic simulation of incidents such as aircraft accidents, terrorist activities, structural fires, major road traffic accidents, wildfires, or natural disasters, for training and planning purposes.

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.
