GM No 2 to Appendix XII - Competence and experience of pilots for Category 3 and Category 4 flight tests and of Lead Flight Test Engineers (LFTEs)

• ED Decision 2015/026/R found in: Initial Airworthiness and Environmental Protection (748/2012) Part-21 Part-21L (Jul 2024)

GM No 2 to Appendix XII – Competence and experience of pilots for Category 3 and Category 4 flight tests and of Lead Flight Test Engineers (LFTEs) ED Decision 2015/026/R Definition of similar ‘complexity and characteristics’: Similar ‘complexity and characteristics’ for aircraft can normally be assumed for aircraft of the same category and in the same class, and certified under the same CSs, e.g. CS-23/CS-25. However, it could be considered that aircraft certified under different CSs but having small difference in weight and operating procedure (e.g. Citation 525/Citation 550, 560) have similar complexity and characteristics. Flight experience of LFTEs: The flight experience includes experience as a crew member in flight tests or other flights (e.g. flights as a student pilot or with a pilot licence). ##### GM No 2 to Appendix XII – **Competence and experience of pilots for Category 3 and Category 4 flight tests and of Lead Flight Test Engineers (LFTEs)** *ED Decision 2015/026/R* Definition of similar ‘complexity and characteristics’: Similar ‘complexity and characteristics’ for aircraft can normally be assumed for aircraft of the same category and in the same class, and certified under the same CSs, e.g. CS-23/CS-25.
