Well, this time I just want to know a bit more about Kreuger flaps. How were these different from the norm? It seems they were not too successfull, seeing they are not used anymore on modern jetliners. What were it's pros and cons, and how were they different from normal leading edge flaps? Also, I see that the A300B4 was produced with Kreuger flaps, but the earlier A300B2 did not have them. What kind of flaps did the B2 have?
