"Is that a step-change at 8000'? Must be a right PITA in the descent! The CJ2 has a similar step-change at about 6000' IIRC and it was always a challenge to remember to slow down enough to stop the overspeed klaxon sounding."
I don't see how it is a problem seeing that you have to be at 250 kts below 10,000' in most if not all airspaces in the world.
