Oh for gods sake, not again!
There is no magic method that is universal to all types or organisations.
Stick and power work in concert ... Power & Pitch = Performance and different types/scenarios/organisations use different techniques to apply this.
So often in light aircraft, students are taught to use power to control sink and stick to control airspeed, but in airliners it is common practice for instructors to teach speed control with power, sink rate with stick.
Do we really need another 87 posts? I'm losing the will to live
I would advise any students reading this thread to listen to their instructor and follow the technique that they are taught.
Ands BTW, My Data, you can easily control a PA28 by using power for speed, stick for sink rate, I've done it and it also responds well to the opposite approach - in short, it is a very forgiving, docile aeroplane.
