A few years ago, as my need to travel on business to various locations ill-served by the airlines grew, using a GA airplane was a natural solution. After months of making, missing and rescheduling appointments, conducting business in FBO meeting rooms and up to four sales calls a day, I started to get the hang of it. What I learned about weather flying and fitting small airplanes into the ATC system would fill several magazines!
But one of the more vexing problems I encountered after a few days on the “road” was fatigue: I needed a couple of days to fully recover my energy after a business trip in my high-performance single. I generally use supplemental oxygen above 10,000 feet—8000 at night—and scheduled things so I always could get a good night’s sleep. But I just couldn’t shake the fatigue.
