In the NACO plate for ASH ILS 14, the GS intercept altitude (1800') is
labeled "LOC only". How can a GS intercept altitude apply to the LOC
approach and not to the ILS approach? Is this a charting error?

The note is a mistake. That note is supposed to appear only when the
G/S intercept altitude and the LOC FAF crossing altitude differ by more
than 20 feet.

The procedure will be corrected by NOTAM sometime next week (or so they
say. ;-)

Where the GS intercept and the LOC FAF crossing altitude differ by 214
feet in the Nashua procedure why would the note be a mistake?

That's not what's happening. When you're flying the ILS, you'll intercept
the GS at 1800MSL. When you're flying the localizer approach, you'll
cross the FAF at ... let's see... 1800MSL ;-)

Oh, OK. So basically the 1800' intercepting the glideslope is
extrapolated over to the LOM because without the glideslope you have
no other altitude to hold until that point. The note made sense to me
when looking at in relation to the plan view, but I use Jepp charts so
didn't look too carefully at the NOS version.
