Re: 737NG emergency descent procedure...
I'm surprised that the lessons learned have not been passed on!!
At the time of the Aloha 737 peelback some criticism had been levelled at the crew, in that they 'used' high speed descent,possibly agravating the situ.
The Industry then seemed to accept the Modus Operandi that in the event of an 'explosive' decompression,slow speed(actual) descend would be used to preserve structural integrity.In the event of a Pressurization concern(cabin warning horn above 10000')high speed clean descent would be used to expeditiously 'catch' the climbing cabin...
Possibly the training dept's haven't passed it on??
Keep it simple?
Cheers
