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.


Do you have a link to the TSO handy? And is it the full requirement? Last
time I tried to read TSO C129, seems like it was a skeleton document,
referencing a commercial spec that had to be purchased.



Same with 145/146. The nuts-and-boths is in RTCA Doument 229C. $350.
