Capn Bloggs does not need me to defend him, he is quite capable of defending self, but I will say he IS extremely qualified when it comes to GPSNPAs.
The crux of what he is saying, and I agree is- you need to have something to increase situational awareness when you dont have a flash ND, and having a fix that references distance to go to the field so that one can easily calculate descent profiling surely is the way to go.
