Hi guys,

Unlike the elevators and rudder that change an aircraft's pitch and
yaw with no other secondary effect, why does the banking of wings by
the use of ailerons not just roll an aircraft but also produces a turn
(yaw)?

Very basically, because the wings are producing lift. They continue
to produce lift no matter what angle the airplane banks to. When the
wings are banked, the lift pushes sideways now, not straight down
anymore. So the airplane now lifts around in a curve.

Logically, one would expect an aircraft to keep going straight
ahead even if the pilot banked the aircraft left or right. Where does
the turning effect come from?

Lift. Bank the airplane sideways and the lifts around in the
direction of the bank.

Is there a website you know of that can teach me such basics, without
having to bug you?
