That's from hypoxia. Being in an airliner is equal to being at about 5,000'. The reduced air density means less oxygen and you get fatigued (also reduces cognition, coordination, vigilance and night vision).
- caymanjim 8y agoCloser to 8000' in commercial airliners. While it's technically hypoxia, insofar as it's less oxygen than at sea level, I don't know if 8000' is enough to cause the effects you're describing. Anecdotally, I'm a fat smoker, and I don't seem to notice any of those negative effects at 8000', but I certainly notice them at around 12000' or so.
- travisjungroth 8y agoI didn't realize it was that high. I guess I was remembering from the Cessna 421 I flew, but we were cruising at more like FL250. Looks like the 787 brings it down to like 6k though.
