Central Load Control is here to stay as frankly it works well for most airlines. Gone are the days when you need individual employees at each station to be responsible, prepare and run out the paperwork. Now thanks to technology a group a fraction of the size can accomplish the same on a global basis.
In addition tie in things like ACARS, gone are many of the previous delays such as waiting on loadsheets, notoc’s etc as planes can taxi out ontime and receive their numbers on the way to the runway.
Just like how airlines can today flight plan and dispatch from single global facility and must not rely on regional offices to create flight plans as in the past, they can very successfully provide load planning and weight and balance functions from centralized set ups.
