So my question is why are we still using ailerons and not spoilers
Many airplanes are using spoilers. Many commercial airliners for example. Of course, they usually have both.
so it seems that the spoilers are more efficient.
Not always.
How come the propeller driven aircraft manufacturers(Cessna, Piper, Beechcraft, Lockheed Hercules, etc.) continue to use ailerons instead of spoilers?????? Why????
One reason: differential ailerons
Another reason: better control of the roll axis than spoilers
