The POH for my TB-21 (turbocharged Trinidad) with a
Lycoming TIO-540 calls for putting the mixture full rich
prior to landing. Is that different from what most people
do with this engine?

What actual model engine does the TB-21 have? Just knowing that it's a
TIO-540 doesn't give us enough information to compare with our own engines.

The engine in my plane, a TIO-540-AA1AD, cannot stay running at full rich at
idle at high density altitudes, as I mentioned in another post. I put the
mixture to full rich before landing only when landing below 3000' or so (and
then only so that I am more prepared for a go-around...operationally, I wind
up leaning again after leaving the runway so that the plugs don't foul).
