WTD: Some handling operations at some airports allow a dispatcher who hasn't been on a load control course (ie. doesn't know how to produce a computerised loadsheet) and hasn't been trained in drop-line loadsheets, to sign a computerised loadsheet to say it's correct. Other airports' handling operations don't allow such dispatchers to sign anything "because they're not trained and therefore can't take responsibility for it," which is quite right in my view. Perish the thought, IF an incident was to occur during take-off, who would be held responsible? The load controller who built the loadsheet, or the dispatcher (who isn't l/c trained) who actually signed it???
