WAAS, in the long run, probally has its best advantage if it can do curved

WAAS has nothing to do with RF legs (curved approach paths). RF legs are a leg
computation done by an RNAV/LNAV platform. WAAS is an augmentation scheme for
GPS. RF legs are independent of the nav sensor, although GPS is presently the
preferred sensor for RNAV/LNAV. So, there is no reason that a TSO-C146 (WAAS/LPV)
couldn't do RF legs with, or without, WAAS and or LPV.
Having said that, I haven't heard of any proposed implementation along those lines
for WAAS and LPV.
