Hi Umberto,
Whenever I make an approach to RWY 36R at KCLT I get to 20ft and just about to flare when the runway suddenly comes up to meet me, causing my landing rate to be between -500 and -600ft/min. I have ORBX Vector installed, but as many other threads have mentioned, KCLT isn't one of the available airports to fix in their config tool. I read your post about the sloping runways at KCLT, could this be the issue?
Thanks
Mike
