Lovely weather -- today was probably a 6-hour day. But I am not a 6-hour pilot today!
First, I again learned that the fuel valve must be open for the engine to start.
Second, the temp at 6500 was -3C., and I again learned that when we get cool the vasculature shrinks and lots of extra fluid goes into the bladder.
Third, I learned that supplemental oxygen, even at these low altitudes of 4000-6000 ft msl prevents my "sopite syndrome" symptoms of drowsiness, as suggested by a pilot at the WGC in January. And it also prevented my usual post-flight lassitude.
It was pretty windy today, with gusts to 18 kt at takeoff and to 15 kt at landing. Usually, such conditions produce streeting, but not so much today because the thermals cycled rapidly. That is, I looked at a nice little tight cu 4-6 mi away, and by the time I got there, it was dissipating, leading me twice to the low end of the lift band.
The secrets today to finding lift were to sniff at the upwind side of the markers (and to find sink, to approach a cloud from downwind!) -- as usual --
and to look for new puffs. More than once I flew to a cloud, found it dead, and headed out into the blue -- and soon felt a thermal, turned, climbed, and as I climbed, saw first a wisp and then a cloud above.
So there was lift everywhere, just not always under clouds.
Due to multiple factors, I quit after only 3 hours. The afternoon sky looked as though the usual late-afternoon consolidation of thermal sources, with broader areas of lift, occurred.
