Who is allowed to occupy the flight crew seats on an aircraft?

The correct choice highlights that only individuals who are Air Canada flight crew qualified on the specific aircraft types are permitted to occupy the flight crew seats. This requirement is grounded in aviation safety and regulatory standards. Flight crew members undergo specific training and certification relevant to the aircraft they operate, ensuring they are equipped with the necessary skills and knowledge to respond to in-flight situations.

While cabin crew members play vital roles in maintaining passenger safety and comfort, they are not qualified to handle the operational responsibilities of the cockpit unless they possess the requisite flight crew qualifications. This distinction is crucial as passengers or non-qualified employees cannot assume those seats due to the need for trained personnel to manage emergencies effectively. Therefore, having only certified flight crew in those seats reinforces safety protocols and operational integrity during flight.
