The image below is of an FAA "Instrument Approach Procedure"
The entire thing is the "Procedure"
It contains a "Procedure Turn", which when not required typically states: "NoPT"
Now, in some places it states "Procedure NA" (red arrow near top) which seems to implicates the entire Procedure NOT the Procedure Turn. However, the red arrow indication at top also seems to implicates the Procedure Turn because we're basically straight in from that location, so it wouldn't be needed, But again, NoPT would make more sense. And why would the entire procedure be NA?
If we look at the two "Procedure NA" notes on the plan, then the entire "Procedure" would be NA from most approach directions.
So, Which is it? Does "Procedure NA" mean The entire Instrument Approach Procedure? or just the Procedure Turn? If just the Procedure Turn, why does it use different vocabulary? Why not just say NoPT ? Is there some other significance?
I looked in the chart user guide and can't find "Procedure NA" in it
