62 Composition of Focus Group US Airways WestJet The focus group included individuals from a number of organizations, including deicing service providers, passenger It should be noted that a concerted effort was made to airlines of varying sizes, cargo airlines, government agencies, include individuals involved in deicing operations in North and airport authorities. These individuals were invited to the America, Europe, and elsewhere in the world. The following focus group because they are key decision makers for aircraft countries were represented in the focus group: United States, ground operations in winter conditions in their respective Canada, United Kingdom, Finland, Norway, Sweden, Ger- organizations. many, France, Netherlands, Austria, Hungary, Russia, and In addition, several key consultants in the deicing industry Japan. were included. These individuals have many years experience in the deicing industry and are now involved in training programs. The following organizations were represented in the focus Survey Format group: The survey consisted of 25 multiple choice and short answer questions. The final question was an optional open-ended Aero Tech Consulting question used to collect additional comments/observations Aeroflot on the topics that were not addressed by the survey questions.
