To think that a Training Department in an International Airline would have to train Pitch +Power = Performance is a BIG concern. At what point in a pilots career should this be learned, I suggest PPL not post ATPL type Rating or recurrent training.
If you look at the standard leaving the ATO's I think you'll find that Pitch + Power = Perf is not something that's really taught any more - at least not in the early parts of the syllabus. Pitch and power considerations ought to be introduced very early on (even E of C) however I don't believe it is these days. Student pilots at large integrated schools are not taught to think for themselves any more either sadly.
