SOUTHAMPTON, Pa., April 12, 2005 -- Environmental Tectonics Corporation's Orlando Simulation Division today announced the successful completion of their third training session at Baltimore/Washington International Airport (BWI) utilizing the multi-user virtual-reality (VR) simulation trainer, the Advanced Disaster Management Simulator (ADMS(TM)).

Following a highly successful exercise conducted last year, ETC was selected by the Maryland Aviation Administration to develop and conduct a series of additional programs to train relevant BWI personnel in several different areas of airport disaster response, including a security breach, a terrorism-related HAZMAT incident, and airline crash landings.

During the last week in March 2005, ADMS was used to train over one hundred BWI first responders in dealing with a mass casualty emergency involving a crash-landed B-757. BWI's first responders, including the airport's Fire Rescue Department, Emergency Medical Services (EMS), Police and Airport Operations Staff, were presented with this rare and extreme situation to train as a unified team headed by joint command. The multi-jurisdictional team was also able to exercise and apply the airport's Emergency Plan under the National Incident Management System (NIMS) for standardized disaster response procedure, instituted by the U.S. Department of Homeland Security.

The exercise begins with a sequence where a plane makes a crash landing after losing power in both engines, landing in the middle and sliding to the end of the runway. When the now split fuselage of the aircraft comes to a rest, it bursts into flames. Through the chaos of the wreckage, smoke, fire, bodies, debris and scattered luggage, survivors can be seen escaping and running away from the scene.

The sequence is shown only to the person assigned as the first on scene. This person becomes the initial Incident Commander (IC) and issues an Initial Briefing to the control tower or emergency operations center, which then issues the alert to all responders. As they are called upon, team leader trainees file into the training room, sit at their ADMS stations and begin to mitigate the situation within their domain. As higher-ranking, more qualified officers appear on scene, they assume command from the previous IC. The new IC continues to enact the emergency plan, navigating his or her view of the scene on a large projection of the 3D virtual world coupled with 3D audio, while communicating with their team leaders who, in turn, issue orders to their virtual teams to execute actions. For each response organization, ETC proctors command the virtual teams by inputting the group leaders' orders into the linked training stations. The results of decisions, actions and commands (or lack of) play out in real time, and are viewed in 3D on each team's station, representing their individual points of view of the scene.

Dealing with security related threats, fire and explosion related disasters and biochemical incidents requires responding personnel to place themselves within the immediate threat of danger and requires them to make appropriate decisions under extreme stress. Simulation training has been proven to be the leading technology in increasing emergency responders' preparedness levels, and ADMS Intelligent VR Technology(TM) allows the exercises to be driven by the decision-making process, providing realistic, yet safe and efficient training.

ADMS systems are currently used by Chicago O'Hare International Airport, Minneapolis/St. Paul International Airport, Orlando/Sanford International Airport, the Metropolitan Nashville Airport Authority, Florida's Office of Emergency Management, Florida's Department of Transportation Consortium, Florida State Fire College, Kawasaki Industrial, UK's Ministry of Defense, UK's International Fire Training Centre, UK's Warwickshire Fire Rescue Service, The Netherlands' National Institute for Fire Services and Disaster Management and South Korea's National Fire Service Academy.
