I brought this exact subject up last year & am happy to see it's back on the agender.
'Pas' yes what you say would be a simple way of dealing with the extra height, start down on say late downwind, abeam the ldg thresshold drop gear & head on down (typical), that's exactly what I/we do to avoid high ROD's.
'airman1' yr right there mate 1500' cts have been in place since Noah took up flying, well for jet types anyway. I believe they brought them in for high perfomance 'anything' because most slippery types fly downwind at say 130-150 kts anyway, LR35 for Eg.
'htb' also correct the whole procedures are 'recomended' as you have highlighted I think mainly because 1500' may not be possible wx wise but still legal visually for ldg.
Like I said once before healthy debate is good
