After being handed over from swiss to Padova........"ahh ***283 stop descent at FL270....." as we were passing FL255, I pressed alt hold as the capt verified our present level....the response was.."ahh is noo problem...desend FL250..and advise when ready for descent"
arrrrrrrgggghhh!
I just laugh now.....put TCAS on the largest range scale..and keep a VERY good lookout.
