While making a turn to base and final recently, I was aware that I was
going to be wide with my normal turn from downwind through base to
final, so I banked more to keep as close to the runway centerline as
possible. I kept thinking about the infamous and usually fatal stall/
spin by some pilots in this situation, I kept thinking that if I keep
the ball centered, even with a very steep bank, that I would be ok and
not auger in. Some of you instructors and old pros...is this correct?
(Not that I intend to make it a practice.)
Instead of asking about keeping the ball centered, perhaps you should be
asking why you elected to flirt with a pilot error fatality by cranking and
yanking for the sake of a few style points... So what if you overshoot the
turn????
Note: as others are beating to death - stall speed doesn't change with bank.
Stall speed changes with increasing G (increasing lift). Increasing G comes
from pulling on the yoke/stick. Period. No pull, no G, no increase in stall.
More pull, more G, higher stall. Wings level, wings banked, wings upside
down - makes no difference.
so if i am doing a steep descending turn , I wont be pulling back on
the stick as much as a steep level turn,
hence less g ? This would seem to contradict others comments that
you pull the same no of g in a bank whether it is level
or descending. I am still confused.

In a coordinated descending turn, the inside wing is at a
higher AOA than the outside wing and will stall first. In a skidding
descending turn, the difference is even greater and is asking for big
trouble. In a slipping turn, the inside wing's AOA decreases and is
much closer to the AOA of the outside wing. Danger of wing-drop
stalling is lessened.
In a climbing turn, the outside wing is at a higher AOA and
will stall first.
I built a device that demonstrates this visually so that our
students could get a handle on it. I keep promising to post pictures
of it somewhere. Can someone suggest to this Internet Ignoramus where
a good spot would be for that?
