What does the Airworthiness Worksheet assist in determining?

The Airworthiness Worksheet is a critical tool used in the aviation industry to assess whether an aircraft meets the necessary safety and regulatory standards to ensure it is fit for flight. Its primary function is to evaluate various components of the aircraft, including maintenance records, inspections, modifications, and compliance with airworthiness directives. By systematically reviewing these factors, the worksheet provides a structured approach to determining if the aircraft is airworthy, which is essential for safeguarding the crew, passengers, and the integrity of the operation.

The other options, while relevant in different contexts of aviation operations, do not pertain to the primary purpose of the Airworthiness Worksheet. Fuel efficiency metrics and aircraft rental costs are financial or operational aspects that do not directly relate to the safety and compliance checks that the worksheet focuses on. Similarly, flight scheduling is concerned with logistical planning rather than assessing the aircraft's fitness for safe operation.
