Aircraft Certification is the process by which an aircraft is evaluated and approved for safety and performance standards set by regulatory authorities. This ensures that the aircraft meets specific design, manufacturing, and operational requirements before it can be used for commercial or private flights. The certification process involves rigorous testing and documentation, including flight tests and inspections. Regulatory bodies, such as the Federal Aviation Administration (FAA) in the United States, oversee this process to ensure that all aircraft are safe for public use and comply with established aviation regulations.
