I agree with the previous posts. Attitude flying is the best way to learn but practically, in a commercial sense, we all tend to fly VFR by power settings.
If I am doing a charter in a 22 or 47 I will pull a comfortable MP and fly on but when instructing ab-initio students we teach attitude and then power to maintain height. Aside from the advantages re Nav's it also helps to give a good appreciation of power required graphs. Some schools don't do this.
Do you talk about both methods? I have seen newly graduated pilots fly along chasing the power all day (well not quite) to maintain height and when I mention just hold a setting and fly, a look of "can I do that?" comes across.
Just wondering.
