As I stated previously, FAA Aero Nav Services, the FAA entity that develops most FAA RNP AR IAPs, will have nothing to do with third-party developed RNP AR IAPs. No review and no QC. Here is the disclaimer on Aero Nav Services National Database Review for the SAV Runway 28 RNP AR IAP. Database review isan important component of the requirement for operators or their authorized designee to validate RNP AR database source.
