Which document is used to show that the aircraft is fit and safe for flight?

• A. Maintenance Control Manual
• B. Supplemental Type Certificate
• C. Certificate of Airworthiness
• D. Type Certificate

Answer: (C)

The Certificate of Airworthiness is the document that certifies an aircraft’s compliance with safety and operational standards, indicating that it is fit and safe for flight. This certification is issued by the aviation authority after a thorough inspection, ensuring that the aircraft meets the necessary regulations and is free from any mechanical issues that could compromise its safety.

Obtaining this certificate is a critical part of the aviation regulatory framework, as it reassures both the operator and the public that the aircraft has passed all required tests for structural integrity and operational capability. It is essential for compliance with safety regulations, and without it, an aircraft cannot be legally operated.

The other documents serve different purposes: the Maintenance Control Manual outlines the procedures for maintaining aircraft, the Supplemental Type Certificate pertains to modifications made to the original design, and the Type Certificate certifies the aircraft's design but does not address the specific condition of individual aircraft for flight.
