An improvement that requires extensive developmental and operational testing to increase an aircraft's range by 20% is known as which modification?

• A. Aircraft range modification
• B. Learning curve theory
• C. Post-production support
• D. Termination for convenience

Answer: (A)

Extending an aircraft’s range through a change that needs extensive developmental and operational testing is a range modification. This term is used for a formal change aimed at increasing performance, requiring a validated design, flight tests, and regulatory acceptance before the modified aircraft can enter service. It highlights that the modification directly alters capability and must be proven safe and effective. The other ideas don’t fit this scenario: learning curve theory explains productivity gains as teams gain experience during production, not a hardware change to the aircraft. Post-production support covers maintenance and updates after delivery, not introducing new performance capabilities. Termination for convenience is a contract provision about ending an agreement and has no technical relevance to modifying the aircraft.
