CTD,
My thanks for your posting - it helped me to understand a little better the difference between our ground topping and air topping procedures. I still have a problem with the local pilots though; one of them has interpreted a maintainers manual comment along the lines of "..if the RRPM droops below 97% in flight.." to mean that on the B212 it is perfectly legit to bring it down to 94%! He's unable to show me anywhere that positively allows it, and I've shown him plenty of statements that the min limit is 97%, but I have the nagging feeling that he still does it his own way when he's flying. Ho hum.
