Ramp Dispatcher is probably one of the best jobs you can do at the airport. Working for Servisair will allow you scope to get to work on a huge variety of a/c too. You will be the focal point for all staff involved in the turnaround. You will need to be able to communicate at every level too...pompous flight deck, finicky cabin crew, hairy-arsed baggage handlers....Even on a bad day, it's still pretty damn good!
Oh and BTW, the Loadsheet must only be signed by someone who can confirm that the aircraft has been loaded safely and in accordance with standard loading for that a/c, as well as any LMC's...you must be trained on Load Control to some degree.
