Anyone give me a clue of the approach configuration of R172K? For
instance, now I use 100kts, 15inch, 2500RPM with no flaps for the
precision approach (ILS) for the training but it is not stable and too
fast for landing after DA.

I insist 90kts is good speed for the approach level and the precision
approach for R172K but my instructor suggested 100kts in terms of some
reason like the strong wind of winter.

I would appreciate if someone could show me the power setting of
approach configuration like non-precsion, precision, approach level for
R172K. Thank you.
