As Pilot-In-Command of a commercial air transport operation, what must you ensure about all equipment?

The requirement for a Pilot-In-Command (PIC) of a commercial air transport operation emphasizes that all equipment must be serviceable and compliant with regulatory conditions. This is crucial because the safety and airworthiness of the aircraft hinge on ensuring that all systems and equipment meet the established standards laid out by aviation authorities.

Regulatory compliance involves adherence to regulations set forth by relevant aviation authorities, ensuring that the aircraft can operate safely under its operational specifications. The PIC is fundamentally responsible for the overall safety of the flight, including verifying that all equipment is functioning as expected before initiating a flight. This encompasses not only the operational status of the equipment but also the compliance with applicable regulations that govern flight operations.

In contrast, while compliance with a manufacturer's Minimum Equipment List (MEL) can be important in certain operational contexts, it does not cover every aspect of equipment serviceability and regulatory compliance—thus, it cannot be the cornerstone of the PIC's responsibilities. Similarly, while having equipment inspected by licensed engineers is significant, it does not absolve the PIC from the responsibility of ensuring that all equipment is ready for flight. The PIC must take an active role in confirming that everything meets operational and safety standards, rather than relying solely on external inspections.
