Thanks ITCZ,
Nasty business really isn't it??
That was a very interesting read thanks again!
So it is an airframe limiting VS, obviously taking any damage into account, I was chatting to a couple of Lear pilots and they were telling me they could get the aircraft to decent at 16000 feet per minute, incredible!
What type of rates are talking about with a 737/320 type?
Not taking any structural damage into account.
Sorry about my shocking knowledge on crew respirator equip that was pretty much all guesswork on my part!
Thanks again!
