HI'er - yes I agree. I was really just talking about the terminology. I think in most cases for an "Emergency descent" due to pressurisation problems, you would actually rarely accelerate to Vmo/Mmo, unless you knew exactly what caused the problem. Moreover given the 737s terrible speed control, you would be reluctant to go near the limit anyway.
I guess my point is referring to the Emergency descent checklist, why is there a checklist to do a highspeed descent on the 737? For example the 767, had attached to the bottom of its rapid depress checklist, how to carry out a descent as a note, not a checklist as such... Then if we look at the 737 emergency descent checklist, it leaves out half the steps you actually need to do, to make it descend with out stalling ..(ie Press LVL change) (I understand that this is becuase it assumes your handflying, not using the automatics)
