The requirements for testing and inspection and instrument static systems required by 14 CFR 91.411 are contained in

• A. Part 43, Appendix D
• B. Part 43, Appendix E
• C. Part 23, Appendix A
• D. Part 91, Appendix B

Answer: (B)

Understanding where to find the exact steps and timing for testing pitot-static and altitude-sensing equipment is key. The requirements for testing and inspecting instrument static systems under 14 CFR 91.411 are published in Part 43, Appendix E. This section lays out the procedures, inspection steps, and intervals you must follow to ensure the pitot-static system and altimeter readings remain accurate. The other appendices cover different maintenance topics, so they don’t provide these specific pitot-static/altimeter testing requirements.
