Forgive me I am new to this forum, but cannot understand the comment below uttered by Tony_EM concerning Aviance
"They can't even provide the load plans and trim sheets for the aircraft they handle, expecting inexperienced L/Cs to trim a DC10 with an A300 trim sheet."
With his vast experience of handling numerous carriers, surely at some point he would have realised that airlines supply their handling agents with such documents and not his management.
Their only failing I can forsee is not having a system in place where one of the experienced dispatchers was made responsible for stock control.
In meantime look for the B****rd who took the last pad out and didn't tell anyone that he / she had done so.
Failing all get carrier to move onto CLC and all your problems would have been resolved.
