On an average day, a pilot will spend a great deal of time attempting to "core" thermals. That involves mentally visualizing the sailplane's position relative to the thermal's vertical anticyclone column center, and guiding his sailplane to circle as near to the center of it as he is able. Why do you write "anticyclone" Larry. This would mean that all gliders would circle righthanded to stay as close to the core as possible thereby using the headwind of the thermal. I have never found a meteorological reason to circle in a certain direction. Most pilots circle lefthanded just because they were tought to do so in the vicinity of their home field. However in x-country flights there is usually no preference. In low situations the pilot usually circles in the direction he feels most comfortable. Sometimes the gliders feels better when circling to the right rather then to the left is my experience. Karel, NL "Eric Greenwell" schreef in bericht ...
