With ref to the above and as an ex Loadcontroller myself - it is quite correct that the loadcontroller to put his name on a automated loadsheet - what the dispatcher is signing for and is required to do by the ANO is to MAKE SURE that the way the load be it cargo/passenger's or baggage is loaded as per what is on the loasdsheet.
He/she does not need to be a fully a qualified load controller but they do need a little knowledge of weight and balence - but all they are really doing is to ensure that the loading is as per the loadsheet instructions and are to signing to that effect.
I hope this help's..
