What must both pilots review prior to flight?

Both pilots must review the MM01 back to the last Airworthiness Release prior to flight to ensure that the aircraft is in a safe and airworthy condition. This review is critical since it provides essential documentation of the aircraft's maintenance status, compliance with regulations, and any repairs or modifications that have been performed. This documentation helps the pilots verify that the aircraft has been maintained according to the standards required for safety and operational readiness, helping to minimize risks during flight.

While reviewing weather reports is also important for flight planning and safety, and the aircraft's maintenance manual provides information on operational procedures and troubleshooting, the specific requirement to check the MM01 aligns directly with ensuring airworthiness before departure. Passengers' preferences, while relevant to customer service, do not impact the fundamental operational safety and readiness of the aircraft.
