Final answer:
Certain positions on the position sign up chart for international flights remain consistent, including the Pilot in Command, First Officer, and key cabin crew roles like the Purser, due to regulatory and operational requirements.
Step-by-step explanation:
On international flights, certain positions on the position sign up chart remain consistent due to regulatory, safety, and operational requirements. The positions that are generally fixed include the Pilot in Command (Captain), First Officer, and key cabin crew roles such as the Purser or Lead Flight Attendant.
These positions are crucial for the safe operation of the flight and compliance with international aviation standards. Specific positions like those responsible for security, emergency procedures, or passenger service are designated by the airline and are crucial for meeting regulatory requirements and ensuring a safe and efficient flight experience for passengers.
These roles remain the same across flights to maintain consistency in responsibilities and to ensure that crew members are familiar with their duties on each international journey.
