CULVE is 1.6 nm from the threshold. If you cross it at 1120, you're 945
feet AGL (referenced to the runway surface). So, to hit the numbers, you
need to keep a 590 ft/nm descent gradient from CULVE to the runway.
Looking at it another way, at 90 kts and no wind, you need an 885 ft/min
descent rate. That's fast, but not outrageously so. It's about twice as
steep as an ILS.

Maybe easy in a 172 but not in my Mooney. With gear and flaps out and
power at idle I don't think I can do 885 ft/min without a lot of
slipping. Even if I could there is still the issue of going from 90
knots approach speed down to 70 knots threshold crossing speed. This
is why I was 3/4 down the runway. I'm still wondering how the
GulfStream did that.
