Default Myth: 1 G barrel rolls are impossible.

What happens to the g force acting on me as a pilot if I start in
straight and level, unaccelerated flight, and then I initiate a
coordinated turn?

The net force increases, as it results from both that induced by gravity
(which is constant) and that induced by your acceleration torwards the center
of the turn. In a coordinated, level turn, the force vector will be normal to
the airframe, and so you will have the impression that you are climbing
initially; when you finish the turn you'll have the impression that you are
descending briefly. This assumes that you keep your head level with the
wings.
