Sorry merlinxx
I don't entirely agree with your "Flight Dispatcher" definition; In the UK ie. not an FAA type Dispatcher. The Ramp/Turnround coordinator may just be a Load sheet deliverer with some ramp services coordination thrown-in. But, equally may be also a "Load Controller" with as much knowledge and just as qualified as any Ops Bod type dispatcher that you describe.
I myself still work on the ramp at times; but, have been working in various aviation roles including ATC, Ops, Met Observer, Bird Scaring, Notam/Crew Briefing and Flight Planning, Load Control, A Triple A Appointed Person, Jetty/Jetbridge Driver with inside knowledge of literally dozens of airlines including US ones with close supervision and coordination with the US FAA dispatcher back in the USA and with some 28 years aviation experience both Military and Civil and hold all the City & Guilds qualifications and I consider myself to be a " Flight Dispatcher"
If you just work in an Airline Ops department - You're really just an Ops Controller or his/her assistant. Not necessarily a Flight Dispatcher in my book.
A Flight Dispatcher is not such a Black and White title in my opinion; hence, the obvious confusion surrounding the position in the UK.
