Elevator for speed, power for ROD - tosh!
Why use power to control ROD when this technique only works on props? The point and power "jet" technique works on everything with an engine (helos and airships excepted) - regardless of what type of power unit it is.
On a jet aeroplane (e.g. any jet airliner) the only technique that works is point and power - so if that is the ultimate aim for a student, why teach one technique on ab-initio and then have them re-learn how to fly on a type rating?
Use the pitch attitude to make the aeroplane fly the desired flight path and use power to control speed (after all, this is what you do when flying level!). It works for all approaches - instrument and visual, precision and non-precision.
One problem - no offence intended - is that a HUGE proportion of FIs have never flown big aeroplanes and don't realise that point and power is essential.
