A 'Loadsheet' requires ownership by the allocated Load Controller or Dispatcher (So for a ACARS loadsheet, this is done by Login reference). If the Loadsheet has a computer printed name on it then it can be traced back to the originator. However, as a Load Controller myself and a frozen ATPL holder, I always ensure that a loadsheet has a printed name, and a signature....This way everyone is happy including the DETR!!!!
