you can see the current implementation of XCSoar at http://bugs.xcsoar.org/raw-attachmen...51197415_n.jpg

if you look close, you notice a blue line originating from the center of the thermal assistant. the other end of the line marks the point of the proposed thermal core and shows you the direction in which you would need to recenter. from what you've mentioned in the previous posting I understand that this indicator needs to be larger and possibly in an arrow-like form, correct?!

there is also an alternative implementation proposed that looks like this: http://bugs.xcsoar.org/raw-attachmen...lassistant.png
feel free to comment on that one too. we are always open to suggestions and constructive criticism.
