Airprox - absolutely right, mon brave!! When you're NOT aiming at a specific point on ther ground then yes, control column controls attitude and hence speed, throttle controls rate of climb/descent at a constant airspeed. But when AIMING at your touchdown point, assuming that you've achieved an acceptable descent point, then the interrelation of the control column and throttle to sort out 'point and power' is so, so easy to teach and use!! I teach it both in little spamcans and in large 4-jets and, as Airprox says, students catch on to it very, very easily!!
