In practice you always set the prop to max RPM on approach
OK. I'm setting myself up as a target, but not me!
In the 182 towplane I fly, after takeoff, I bring the RPM back to 2300 rpm for noise abatement and leave it like that for the remainder of the flight, including the landing, again for noise considerations.
Now if I had to go around in an emergency, of course I would go to full fine, but I have determined (at altitude) that going around without changing the rpm and with those lovely barn-door (40 degree) flaps down, the rate of climb is more than adequate, even at DAs of 5000-6000'. I should confess at this point, that I am flying behind a P Ponk engine - 265 HP.
