n this episode Bill takes us on a deep dive into the physiology of hypoxia, sleep and aging and what we can (and should) do to help combat the effects of each when it comes to flying. Hypoxia can greatly reduce our mental acuities, often without our knowledge. It can be sudden and can be radically different from day to day. The bottom line- when operating at altitude even the most prepared and acclimatized need to build in more margin. Come along as we explore three subjects which can really impact our safety and ability in the air.
