hugmonster - full marks, im with you.
regardless of whether the load sheet is generated remotly by another person, or not, it is still the responsability of the loading supervisor and captain to ensure that the flight has been loaded correctly - as defined by the ANO. this is quite clear enough! thefore the ramp agent (or loading chief) should sign to state that they have loaded or witnessed the loading correctly as per operators instructions. this simply can't be done remotly.
point to note - generally it is the ramp agent who will pass final figures to his/her office for completion of the loadsheet. therore the person in the remote office will still rely on (his eyes and ears) the ramp agent to ensure correct details are obtained.
i will find it very hard to beleive that dispensations have been granted along theses lines in day to day operations.
