Which identifiers correspond to an LD-4 unit load device?

An LD-4 unit load device is specifically designed for the transport of cargo and baggage on aircraft. This type of container is commonly utilized by airlines for efficient loading and unloading processes.

The identifiers associated with an LD-4 container are critical for identifying the type of unit load device in use. The identifiers DQL and DQP are specifically designated for LD-4 units. This is important for cargo handling and proper categorization within logistics. Proper identification helps ensure that the right type of container is utilized for transportation, which aligns with the requirements of both the airline and safety regulations.

The other options do not correspond with LD-4 identifiers. Each of those has been designated for different types of unit load devices, making it clear that they cannot be associated with LD-4 units. This distinction fosters clarity and efficiency in cargo management across airline operations.
