Whew! Glad I didn't ask anything political!

OK, things to clarify:

In the Arrow on downwind I've already pulled out a lot of power and
flattening
the prop really does have minimal noise effect.


Just monitor your tach when you do this. You should not go over about
2300 RPM, or you are pushing the prop forward at too high an airspeed.




In the Six, which has a three-blade prop, I have to carry more power of
course.
Next time I fly it, I am going to listen more carefully while flattening
the
prop on downwind and see if there is much noise effect. I haven't been aware
that there is. That airplane, though, is quieter than anything else in our
fleet (Archers, Warriors, the Arrow) because of the prop. So maybe not an
issue
there either, even with the O-540.

I like to run my checklist, really a "flow," on downwind, base and turning
final. And I like all three to be the same because the point of doing it
multiple times is that if I get distracted by ATC, traffic, or airplane
problems, any one of them will have gotten the job done. It's a matter of
style, I guess.

Things learned/confirmed:

The issue is only noise; no engine issues that I heard anyway.


No -- you CAN overspeed the engine if you push the prop full forward at
too high airspeed. Monitor the tach!



I like Bob Gardner's suggestion that going full forward may not be necessary
at
all unless the tactical situation demands it. One more thing to remember on
final, however.

I like the several suggestions that the go-around mantra be "everything
forward"
-- in fact I wish I had been drilled on that one while training for my
Private.



Too much drill, not enough reasons for the drill. I do not add full prop
until I am at gear speed.

So what's wrong with doing it on downwind? (This in a Cherokee 6 or and
Arrow) It seems to work fine, does not disarrange the engine, etc. I
suppose there is some small noise increase, but hardly much.

So (1) is everyone taught to do it on final? (2) Why? (3) What's wrong
with doing it on downwind?
