FlightPathOBN:
3rd party design get full review from many different parts of the FAA. I designed and submitted PSP, SCC, and parts of BDL from beginning to end with the FAA.
The 8260 forms are required and reviewed, waivers are reviewed, the procedures are required to be sim checked, obstacle validated, and flight validated.
It AFS 420/460 and AVN that deal with procedure design.
I understand that. Nonetheless, my statement is correct. The real QC expertise lies within Aero Nav Services, because they design and QC FAA-developed RNP AR IAPs all the time.
As to ASF, I have no involvement with the third-party process, but I understand AFS-460 has that program.
AFS-420 may provide some ad hoc input, but as your mission statement sets forth, they develop the TERPs standards and maintain the 8260.19 handbook.
I deal with both Aero Nav Services and AFS-420 all the time.
The Aero Nav folks have my picture on the wall for dart practice.
