What message code should be entered in DLTerm for communicating with the Load Planner?

The message code that should be entered in DLTerm for communicating with the Load Planner is JLAV. This specific code is designated for load planning communications, allowing the necessary data regarding payload distribution and load assignments to be transmitted efficiently between the operational teams and the load planners. Using the correct message code ensures clarity and accuracy in the logistical processes, which is crucial for maintaining safety and efficiency in flight operations. The other codes, while potentially relevant to other functions within the system, do not specifically pertain to load planning communication. This makes JLAV the appropriate choice for any messages directly relating to load management tasks.
