For an interesting GPS GP, look at the Jepp chart, if you have it, for
the
RNAV (GPS) RWY 28 at KPQI. The GP starts down about 0.3 NM after the
FAF.
This appears to be done in order to meet a crossing altitude restriction
insice the FAF, and still have a profile that brings you to an
appropriate
height closer in to the runway.



I only have the NACO chart, and it doesn't show up that way. Shouldn't
they
be the same if it is necessary to meet obstacle criteria?





I don't use NACO charts, but could it be that on the NACO chart, the 3.25°
notation only applies to the segment after PESIC?



It ought to apply to the final approach segment. This all sounds familiar,
like it has come up before. I don't remember how it was resolved, and it is
too late to dig through TERPS to try and figure it out. I'm going to bed.
:-) Maybe tomorrow will google the ng for KPQI.
