JunkHole61 Thank you very very much ....indeed that's what i am looking for.
in this case...my freind the controller here in my home base was right with what he instructed us to do.
may be he was mixing the two methods together (
Speed reductions prior to descent. & Speed reduction following descent.).
i will pass this link to him...to clarify the procedure to him ( what a freind for 
)
thanks a million
