Nacelle Chines or Strakes are aerodynamic devices on aircraft engines that regulate airflow, preventing stall and increasing lift. They are found on nearly all jet airliners, including Airbus and ...

"In Dutch roll, the aircraft experiences a rolling motion primarily driven by the design (dihedral effect) of the wings, ...

Since a simple two-channel plane has no ailerons to bank the plane, the rudder itself, in conjunction with dihedral wing design (where the tips of the wings are at a higher elevation than their base), ...

To keep the plane simple, he got rid of ailerons entirely. For roll stabilization he angled up the wings noticeably, adding dihedral. This gives the aircraft passive stability, because as it rolls ...
