Of course, the real, full sized ships never raise the ailerons in landing configuration ! Rather, and as mentioned before as well, they drop it together with the flaps !
BUT, and that`s the vital point here - all the big ones (at least the ones I have flown) have a HORIZONTAL STABILIZER TRIM ! So they can counteract the resulting pitch down moment that normally occurs upon flaps ( and possible aileron down movement ) with the pitch trim ( adjustment of the whole horizontal stab ) and ergo, they still have the whole range of that ELEVATOR deflection at hand to control the approach angle and of course the landing flare !
Very true. Perfectly describes the A319/320. And also explains why in "Direct Law" it is critical to keep the horizontal stab in trim, so as not to run out of elevator in the flare.
Now, on the other hand, the L-1011-500 had an 'active control system (ACS) that flexed the ailerons up slighly to reduce the bending loads on the spar at higher weights.
