So long as the final approach path is commenced from an acceptable approach point, 'point and power' works very well in any aeroplane. I teach it on the PA28, I teach it on the VC10.
During Descending 2, the final exercise should show the student the acceptable limits for the approach path from which 'point and power' is commenced.
CC for IAS and power for ROD works until you are aiming at a fixed point on the ground! - after which 'point and power' takes over. Everyone who has tried it agrees - it's MUCH easier and more logical!
