737 glide ratio and speed

[framer]

But is there any other clean solution ? A clean solution would be to use kinetic energy to avoid a so high rate of descent, but in my opinion it's not a reliable technique.
Then, from a 2000fpm descent I would have flared at 200ft.

I haven’t got a good answer for you, just an opinion.
There are obviously different ways to store your energy. My preference would be to store it initially as altitude in a clean configuration, and then, once I have ensured that the energy to make the field is there, I would prefer to store it as IAS in the clean configuration until such time as I want to quickly destroy the excess energy with gear and flap. There are so many variables that it would be easy to poke holes in any approach to this problem ( pun intended).
If the runway is 10,000ft long I would much rather arrive at the threshold at 220kts gear down with the flap blowing back than land short.
If it was ideal conditions I’d aim for 4000ft/10nm/ 230 kts clean and point the nose just short of the threshold and then dirty up when it was clear I had too much energy. If someone wants to try that in the sim I’d like to hear how it works out! My home field is 12,000ft long so that may influence my thinking!

Green banana to hit the glideslope clean at 10Nm/3000' or some similar combo. Then fly a coupled approach. Use gear, flap and speedbrake to slow down at the end.
