You won't find a regulation that says this, nor will you find an FAA
document that proclaims this to pilots. Nonetheless, all TSO-C129
avionics and all higher-end LNAV/FMS platform treat the final approach
segment as the "approach," per se.


The AIM sorta kinda maybe alludes to it when talking about WAAS units.

" The pilot enters a unique 5-digit number provided on the approach chart,
and the receiver recalls the matching final approach segment from the
aircraft database. ....... The pilot should confirm that the correct final
approach segment was loaded by cross checking the Approach ID, which is also
provided on the approach chart. "
