How many "Master Documents" will be kept by the crew during flights utilizing Long Range Navigation Systems as the primary navigation source?

During flights that utilize Long Range Navigation Systems as the primary navigation source, the crew will keep one "Master Document." This single document serves as a crucial reference point to ensure that all navigation procedures and requirements are adhered to during the flight.

The rationale behind maintaining just one Master Document is to streamline operational efficiency and minimize confusion among crew members. In aviation, where precise navigation is critical, having a singular, authoritative source of information helps maintain clarity on navigation protocols and reduces the risk of discrepancies that could arise from managing multiple documents.

In contrast, multiple documents or none could lead to complications in referencing necessary guidelines, increasing the chance of errors during the flight, which makes the choice of one document a well-considered and practical decision for flight operations.
