I agree with Maude Charlee and Captain101; and maybe, just maybe, that's why I feel that flight crew are ever so slightly more at ease with me than with some of my colleagues, since I have an ATPL (albeit still "frozen") and therefore the crew know I understand these matters.
We have indeed had an airline rep/station manager ask some of my colleagues what stab trim was, and they couldn't readily answer... I only wish he would ask me
It is true that in some Continental countries, the "Flight Dispatchers" are more actually called "Ground Ops Co-ordinators" and they stay with the a/c during the whole turnaround and are NOT responsible for doing the loadsheets, only for supervising loading etc.
I also agree that the responsibility to explain these definitions clearly is up to the training dept. with your handling agent - a 2-week course is nowhere near enough in this line of work.
Cheers
