A very basic question

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)? 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?

The wings of an airplane produce lift. When the aircraft is in level flight, this
lift is pointed straight up and pulls up against gravity. When you bank the plane,
the lift now points partially in the direction of bank and pulls the plane in that
direction.

Someone mentioned the book "Stick and Rudder" some time back. That's one book you
could buy. There are many others that you could buy instead. I don't know of much on
the web for free.
