Wing spoilers vs. ailerons??P-61 Black Widow had spoilers....
I read an article that claimed the P-61 Black Widow could turn as tight as the tightest turning U.S. fighter in WW II (even though with the twin engines and massive bulk it is the heaviest and biggest U.S. fighter manufactured in WW II)........the article attributed this to the spoilers in the wings.............So my question is why are we still using ailerons and not spoilers since the ailerons have a opposite yawing effect to the direction of the bank creating aileron INEFFIciency.........while the spoilers have a yawing effect that is in the same direction as the bank adding to spoiler EFFIciency. Also, the spoilers help to rotate the aircraft in the direction of the turn making the turn tighter and quicker.................so it seems that the spoilers are more efficient. How come the propeller driven aircraft manufacturers(Cessna, Piper, Beechcraft, Lockheed Hercules, etc.) continue to use ailerons instead of spoilers?????? Why????
Thanks for your valuable reply.
