For AEI in CTOL mode, the V-22 exhibits a 3800-4000 fpm ROD and 160-170 kt descent speed. As previously mentioned, landing at 0° chews-up the V-22’s proprotors (and probably doesn't do the donks & xmsn much good either), but is seen as a preferable to the VTOL scenario.

The V-22's 4.5:1 wing loading is about the same as that of an MD80.
