For SCUBA DIVING, where decompression stops are needed. there are limited hours to rest before flying. These conditions only applies for:
A. cabin altitude of 10,000 ft and above
B. cabin altitude of 14,000 ft and above
C. unpressurized a/c only
D. pressurized a/c only
E. any aircraft
So far as your question is concerned, a pressurised aircraft is only so so long as the pressurisation kit and pressure vessel function properly. For the concern, treated any aircraft as being (potentially) unpressurised.

Thanks John, very helpful references. Also, even if the aircraft pressurisation system is operating normally, decompression sickness (the bends) has been found to occur as low as 8000ft, which is close to the cabin altitude in most pressurised aircraft.
