Is there anybody that can tell me what the name of the part is on the 737-300 series aircraft, at the wing tip that looks like a miniture winglet? It sits just on the outside of the aileron? It is like a longated triangle. Also, what is the purpose of it? And one last question (for now), what is those longated vanes on the nose dome called, and their purpose?
Thanks in advance to all who respond!
