GM1 21L.A.44(g) Compliance activities for a declaration of design compliance ED Decision 2023/013/R FLIGHT TESTING TO ENSURE NO SAFETY ISSUES EXIST WHEN AN AIRCRAFT ENTERS INTO SERVICE The objective of the period of operation in the final configuration is to expose the aircraft to the variety of uses, including training, that are likely to occur when in routine service to provide an assurance that it performs its intended functions without safety issues and should continue to do so in service. The testing should cover typical routine operations and also some simulation of abnormal conditions. It may be possible to combine flight testing with the testing required to demonstrate compliance with the applicable detailed technical specifications and environmental protection requirements. A substantial proportion of the flying should be on a single aircraft. The flying should be carried out to a continuous schedule on an aircraft that is very close to the final type design, operated as though it were in service and should include a range of representative ambient operating conditions and airfields. ##### GM1 21L.A.44(g) Compliance activities for a declaration of design compliance *ED Decision 2023/013/R* **FLIGHT TESTING TO ENSURE NO SAFETY ISSUES EXIST WHEN AN AIRCRAFT ENTERS INTO SERVICE** The objective of the period of operation in the final configuration is to expose the aircraft to the variety of uses, including training, that are likely to occur when in routine service to provide an assurance that it performs its intended functions without safety issues and should continue to do so in service.
