With LPV, the sensitivity continues to increase (course width decreases)
from the FAF to the runway. That causes LPV to be an angular system
from the FAF to the runway. Not so with other RNAV.


Thanks. I didn't know of the difference. I'll watch for it.

I getting up to speed on the 145/146 spec. The LNAV approach also
reduces in the lateral mode similar to the laternal mode of the LPV
approach. When you reach the MAP, it is only 350 feet full scale
deflection, instead of the 0.3 mile defection for TSO 129 LNAV final.
