Hand on the Throttle
I know a few FAA manoeuvres where you don't alter the power setting, but we don't teach such things under EASA, as flying a rectangular pattern (adjusting for wind to maintain a rectangular track), turning around a point (maintaining an even radius and adjusting for wind) and flying S-turns along a road, aren't seen as necessary lessons and a good skill base to develop in pilots.
Much better sticking to the dated 1940s RAF Air Exercises, and giving students a headache learning a massive pre-landing checklist that includes checking for items not even fitted to their airframe as they pootle downwind.
