opsmaster,
The implementation of Centralised (or Regionalised) Load Control is always a sensitive issue due to the possible loss of jobs at the airports where load control is being removed. This needs to be handled carefully by the organisations concerned.
From a procedural and safety perspective however, the concept is sound and, if implemented properly, does work and works well.
For what it is worth, the airlines that want to do CLC "properly" and not just to cut costs, spend a great deal of time and effort into making sure that their procedures have "checks and balances" in place to make sure that he processes are safe and robust. This specifically relates to communication issues requiring information to be passed by fax or telex, and having all phone/VHF conversations recorded for audit and investigation purposes.
The process works if done properly and should not be criticised when/if it is used "unwisely" by airlines or handling agents.
