This advisory circular (AC) provides the means for conducting IFPV of satellite-enabled PBN instrument flight procedures for both fixed-wing and helicopter aircraft. It also addresses validation of helicopter Wide Area Augmentation System (WAAS) special IFPs. This AC describes ground validation, pre-flight validation (including simulator evaluation and obstacle assessment), and flight validation.
The contents of this document do not have the force and effect of law and are not meant to bind the public in any way. This document is intended only to provide clarity to the public regarding existing requirements under the law or agency policies. Please note that, non-FAA service providers are not required to perform IFPV of PBN IFPs. If a non-FAA service provider chooses to perform IFPV of PBN IFPs, however, this AC provides the directions for doing so.

This memorandum authorizes a deviation from FAA Order 8000.95, Designee
Management Policy, Volume 8, Table 8-1, Minimum Qualification Requirements.
In the Amateur-Built and Light-Sport Aircraft (LSA) Certification block (on pages 8-11

This notice provides guidance and information to aviation safety
inspectors (ASI) responsible for Title 14 of the Code of Federal Regulations (14 CFR) part 135
certificate holders (CH) that operate passenger-carrying, single-engine aircraft under instrument
flight rules (IFR). The information contained in this notice will assist ASIs in determining if
single-engine aircraft comply with the gyroscopic-instrument energy-source requirements to
conduct IFR passenger-carrying operations under part 135, § 135.163(h).
