Aircraft dispatcher training airline flight dispatch trainers Sheffield school aeronautics if you're longing to be a dispatcher.
I'm an FDO since 2003, and after 5 years my boss has decided to give me a chance to go to...I will join them in october,hopefully, and for 6 weeks I'll stay there for a FAA licence course.
Look on their site...there are a lot of threads(from many many guys who tryed it) regarding everything you have to do to reach the course. Fees,tutition,homes,books,endurance,programs ecc...

Stay tuned
