"...American despatcher who seems to do performance and fuel calculations and probably does need to be extensively trained, tho why their pilots can't do their own fuel calcs we Europeans are unable to say..."
wageslave,
The answer to your question is that regulations dictate what's done here in the US. FAR Parts 121.533, .535, .593, .595 spell it out. Parts 121.537 & .597 show the regulatory exception to the requirement for a "licensed dispatcher".
The PIC has the authority to reject the flight plan prepared by the dispatcher and require changes be made if he feels it necessary.
