You state the obvious and I would suggest that the majority of times GA aircraft will fly reasonably straight and level HOWEVER, experience suggests that gliders do something very different and movement is very unpredictable. I do hope glider pilots do not rely on powered a/c giving way. Perhaps I am just too cynical but no doubt all you glider types will tell me why I have this perception!
