(PFDND) happens to be the name of this Computer Navigation Fix.

x identifies the location

(ABCDE) identifies the name

Dont think that is correct.

CNF points are points 5 letter non-pronounceable (like all of the FAA waypoints are :rolleyes:) only used for the internal coding of the FMS for coded procedures.
These waypoints and that nomenclature are establish for coding purposes only such as the centerpoint of a turn. Typically the first 2 letters are the last 2 of the airport, in this case, NGXXX.

They are not represented on charts, and waypoints are not in parenthesis.

Let me bore you more by telling you that you do not have a clue.

It is a computer navigation fix (CNF).

Provide a better explanation for CNF old man....

and show an example...lets not try to make this too much of a bore..

(ask your FAA contacts about unpronounceable waypoints)

Calm down girls :rolleyes:

It's a Computer Navigation Fix as listed in the decode at the front of Terminal books. Bottom left, second pdf page of this:

An explanation of CNFs for you non-believers according to the FAA:

To aid in the approach chart/database correlation process, the FAA has begun a program to assign five-letter names to CNFs and to chart CNFs on various National Oceanic Service aeronautical products. These CNFs are not to be used for any air traffic control (ATC) application, such as holding for which the fix has not already been assessed. CNFs will be charted to distinguish them from conventional reporting points, fixes, intersections, and waypoints. The CNF name will be enclosed in parenthesis, e.g., (MABEE), and the name will be placed next to the CNF it defines. If the CNF is not at an existing point defined by means such as crossing radials or radial/DME, the point will be indicated by an "X." The CNF name will not be used in filing a flight plan or in aircraft/ATC communications. Use current phraseology, e.g., facility name, radial, distance, to describe these fixes.

Scroll down to 1-1-19 Global Positioning System, para j, sub para 2 "Waypoints"

I do find it amusing when someone tries to say that when the people who made something tell you what they made it is in fact not what they made.

Why even have keys/legends if they're going to be ignored?

I know how to read approach charts so there is no need for me to ask.:)


Here is the FAA TERPS Form 8260-2 for PFDND:

I think it means 'Pilot Flying, Do not Disturb'.
