What are the ship numbers for the B767-400ER aircraft?

The correct range for the ship numbers of the B767-400ER aircraft falls within the 1800s. This classification is critical for identifying various aircraft types within an airline's fleet management system. Each ship number serves as a unique identifier that helps in tracking maintenance records, performance statistics, and operational data specific to that aircraft model. Understanding these distinctions is crucial for ramp agents and other personnel involved in ground operations, as it aids in ensuring the right procedures and protocols are followed for each specific aircraft type.

Regarding the other options, they reference different groups of ship numbers that correspond to other aircraft models or configurations within the fleet, which do not apply to the B767-400ER. Therefore, recognizing that the ship numbers uniquely tailored for this specific aircraft model are indeed in the 1800 range is essential for accurate fleet management and operational efficiency.
