very basic answer..

the lift component, vertical and perpendicular to the wings, in a bank is
now pointed off to one side of straight up (relative to earth), there are
now two components to the lift vector, horizontal and vertical, the vertical
lift assists in maintaining altitude, the horizontal component works the
turning tendency.

That is why in a steep turn, more elevator back pressure is required. You
have reduced the vertical component of lift to maintain altitude by giving
some of the lift to the horizontal component. You need to increase the AOA
on the wings to make more lift, to maintain the required amount of vertical
component to maintain the altitude.

again, a very basic answer..
step into the flying laboratory for further exploration of this concept

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?

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

Cheers,
