When should an Air Load Planner consult the aircraft type-specific performance manual?

An Air Load Planner should consult the aircraft type-specific performance manual when determining loading limits and weight restrictions because this manual contains vital information about the aircraft's capabilities and limitations. It provides specific data regarding the maximum weights for takeoff, landing, and any weight distribution constraints that must be adhered to for safe operation.

The performance manual is essential for ensuring that the load placed on the aircraft complies with safety regulations and operational procedures. This information directly influences how much cargo or passengers can be safely loaded, as exceeding limits can lead to critical safety risks such as reduced aircraft performance, potential structural damage, or even accidents.

While other moments, like before takeoff or when filing flight plans, may involve considerations of weight and balance, it is primarily during the loading calculations that the specific details in the performance manual are most critical for safe operations. Consulting the manual immediately before an emergency or during routine tasks only serves to reinforce the importance of proper load planning from the outset, thus making the correct answer about determining loading limits and weight restrictions fundamental to the role of an Air Load Planner.
