Level by, clearances?
When given a conditional descent clearance,for example descend when ready FL200 and be level 20nm before any waypoint,do you expect the aircraft to exactly hit the 20nm before the waypoint at FL200 or can this be descend and level then maintained at a point before 20nm before the waypoint?
I suppose im asking whats best for you guys in ATC,i always go for the point and accuracy but dont always get it,ive been told off for being "late" and high before but have never been told off for being down a bit early.
