Schaloner,
Dispatcher(Ops Controller)? or Despatcher(Ramp)?
For Dispatcher - Flt Ops, usually training provided by the company, most people start as an Ops Assistant(Money not to good but you can gain most of your experience from it). Or Alternatively you can do some prior study with
AVTECH which lead to a C&G cert. or.. go to the State for a FAA Dispatcher Licence.
(With the way JAR OPS goes, it won't require any licence at all). I did my sometime ago through my company, although most Training School say "No prior experience required", that is not ture, most people without any prior experience found it so hard and you are constantly under pressure. I must admit I have a great time there (6 weeks off)
Work wise, depend on what type of operations your company have.But work pattern wise usually 4 on 4 off(2 days 2 night). My typical day usually start with Flight Scheduling, Flight Planning, reading the weather and notams for my sector, flight watch and trobleshooting. Most of my time spend on paper-work. The best things is every day you have difference problem.. shoot-->
To gain experience is best to start with a Charter airline or a Corporate comapny. Since they have no fix schedule you will learn a lot about dispatching in difference area and locations.
For Despatcher - Ramp I don't know much sorry.
Good luck..
