The purpose of the arctic test was to determine the adequacy of the HH-53C, systems and components during operation after extended soaks in an arctic environment. Specific test objectives were to: (1) Determine the adequacy of the HH-53C systems components and ground equipment for operation in accordance with AFR 80-31 and as specified in the aircraft model specification; (2) Determine human requirements, i.e., the requirements for men to maintain and fly the aircraft in an arctic environment; (3) Verify and amplify the results of the Climatic Laboratory tests as well as to determine additional deficiencies revealed by the increased operational capability over that available in the Climatic Laboratory; (4) Test modifications, fixes, procedures, etc., determined from the Climatic Laboratory tests; (5) Determine the cold weather operating procedures to be included in the Flight Manual; and (6) Compile environmental data for future fixes, modifications, and design purposes. Includes attached Addendum.
