Now we're down to 5,000' for night ops, SWMBO?
Here's what the ATSB actually said about the 'recent Hypoxia event':
The ATSB found that the pilot was likely experiencing a level of fatigue due to inadequate sleep the night before and leading up to the incident. Further, operating at 11,000 ft with intermittent use of supplemental oxygen likely resulted in the pilot experiencing mild hypoxia. This likely exacerbated the pilot’s existing fatigue and contributed to the pilot falling asleep.
I've spent many, many continuous hours cruising over 8,000' without supplemental oxygen without falling asleep or making dumb mistakes (or at least not more dumb mistakes than I usually make under 8,000').
The CEO of AEROX wouldn't have any commercial conflict?
