Hi Ron,
I have bad news for others !
In these flight manuals, boeing says there is no flare over the runway
in any of these planes, period
The landing attitude is acquired at the treshold !
When I first got the 757, my autoland could compare to the landing of a pancake being flip in a frying pan, it did not bothered me that much because I enjoy doing manual landings but to keep current I have to do an autoland every 3 months !!

I attacked this problem with two items in mind. The Vref speed over the treshold and the balance of the aircraft at that point. Meaning the attitude.
There is a legal requirement for these aircrafts to land. They must have a stabilized approach under 1000. Full landing cfg, gear, landing flaps.
3 conditions
Vref speed plus add on
proper flight path at the proper sink rate
at stabilized thrust
And these requirements must be maintained throughout the rest of the approach to be considered a stabilized aspproach.
This satisfied, work the balance of the aircraft to give you 1 or 2 degrees of nose up at the treshold. Look at your autoland from an outside view
There should a clear delay for the nose wheels to come down.
Play with the cargo weight, fore, aft until you have it. I do it in Aircraft.cfg
All these CS planes land great in autoland - mine do !!
Dont forget to carry a full reserve of fuel at landing. In the wing tanks.
Once you have the payload where it should be, lock it there for all the flights. Simple enough ? In CRZ the angle of attack is great, as you burn from the wing tanks the attitude will creep forward a bit and you are ready to land either manual or autoland
Happy landing !
