Isn't the MD-11 stabilizer only 2/3's of the original DC-10 stab size?
That's why LSAS was incorporated for Longitudinal Stabilisation.

Furthermore the deployment of Thrustreverser #2 also will create an ANU pitch when the Groundspoilers + Reversethrust is applied. This requires a violent control yoke push. If you try to land an empty MD-11 without this violent push you'll be cracking some tailfeathers upon groundspoiler deployment.

Furthermore, take the time to rollout and never make bets with the Capt to clear the runway sooner than the a/c can handle. The violent vibrations on the CLG brakes (caused by the autobrake) can shorten the lifetime of the CLG hardware or even fail during landing like Alitalia did.

Sorry, never experienced any of that in the last 14 years.

Maybe flying the DC-10 before the MD, one has a greater affinity for the "classic" MD . Coming from the Boeing, where two types that where very different to land (-100 and -200); I find the "11" a joy to land.
The 10's (certainly the -10 10) needs the power held on while the AT are trying to retard. On a light weight AC and forward CG, I'm of the mind you will get a cruncher if you don't keep the power in into the flare.

I would disagree with your characterization that the pitch up required a "violent control yoke push". I would certainly agree that it required some conscious pitch management, however. And again, a software adjustment took care of 90% of the problem. The MD-11 (with the newer software load; I wish I could remember the load number that incorporated the change. 912?) is not a terribly difficult airplane to land even if it is empty/light.

Are you saying that the MD-11 can't handle medium brakes to full stop?

#2 reverser does not spool up above idle until the nose touches....
