First off this issue has been present, and posted about for YEARS now, and nothing seems to have been done. The default 787 has a laughable loss of pitch and control coming through 30 feet agl, every time.
You can configure everything by the book; load distribution, V-Speeds, etc, and still, this poor attempt at faking ground effect particularly in this aircraft will try to kill you on every approach the millisecond you glide through the 30’ agl callout- it will either pitch up widly on its own or drop like a brick depending on your pitch at that point.
Other airliners do not have this artificial ground effect, and Im wondering why this still hasnt been addressed?
