In operations with a minimum flight crew of 2, which of the following is required?

In operations requiring a minimum flight crew of two, having Standard Operating Procedures (SOPs) is essential for ensuring safe and efficient flight operations. SOPs provide detailed, step-by-step guidelines that govern how crew members perform their duties and handle various situations, thereby promoting consistency and safety in the cockpit.

These procedures outline the roles of each crew member, necessary checklists, and protocols for both normal and emergency scenarios. The presence of SOPs helps to reduce the potential for human error by ensuring that all crew members are operating under the same expectations and sequences of actions. This is particularly vital in two-crew operations, where coordination and communication between pilots are crucial for effective teamwork and decision-making.

While a safety management system, flight manuals, and airport slot coordination contribute to the overall safety and operational efficiency of a flying operation, they are not specifically mandated in the context of a minimum two-person flight crew requirement in the same way that SOPs are.
