Well some questions have been asked and not really answered
- ROD if you start from around FL350, boards out and max
mach/IAS will zero out around 5,000 fpm depending on weight -
higher wing loading types such as the MD-80 would go down
faster still - a wide body generally less quickly
- You might not want to fly at Max speeds, however if you have
structural damage
- Pax oxygen lasts for 15 minutes - crew oxygen much longer
- pax have to be on oxygen >Fl130 - Flight crew > FL100
- FL 100 may be below minimum safe altitude on your route, so
there is a lot to think about
- Ear damage during decompress is rare - the problem is the
descent when the air is trying to push its way back into the
eustachian tubes (nothing to do with Euston Station...)
