Final answer:
Aircraft Confined Space Program and Entry Authority (EA) certification requirements are determined by the aerospace engineering industry to ensure safety and compliance within aircraft confined spaces.
Step-by-step explanation:
Aircraft Confined Space Program and Entry Authority (EA) certification requirements are determined by the aerospace engineering industry to ensure safety and compliance within aircraft confined spaces. The American Institute of Aeronautics and Astronautics (AIAA) is a professional organization that provides guidelines and regulations for aerospace engineering practices.
The certification requirements may vary depending on the specific aircraft and its intended use. For example, military aircraft may have stricter certification requirements compared to commercial aircraft. These requirements often involve training, knowledge of safety protocols, procedures for working in confined spaces, and understanding potential hazards.
