Airmen Transition to Experimental or Unfamiliar Airplanes
This advisory circular (AC) provides information and guidance to owners and pilots of experimental airplanes and to flight instructors who teach in these airplanes. This information and guidance contains recommendations for training experience for pilots of experimental airplanes in a variety of groupings based on performance and handling characteristics. This AC does not address the testing of newly built experimental airplanes. The current edition of AC 90-89, Amateur-Built Aircraft and Ultralight Flight Testing Handbook, provides information on such testing. However, if a pilot is planning on participating in a flight-test program in an unfamiliar experimental airplane, this AC should be used to develop the skills and knowledge necessary to safely accomplish the test program using AC 90-89. This AC may also be useful in planning the transition to any unfamiliar fixed-wing airplanes, including type-certificated (TC) airplanes.
Development and Submission of Special Instrument Procedures to the FAA
This Advisory Circular (AC) provides guidance for the submission and approval of special instrument flight procedures that are developed by non-government proponents and submitted to the Federal Aviation Administration (FAA) for review and approval. Special instrument procedures are those procedures developed for specific users and are not processed under Title 14, Code of Federal Regulations (14 CFR), Part 97. Occasionally, the word “must” or similar language is used within this AC where the desired action is deemed critical. The use of such language is not intended to add to, interpret, or relieve a duty imposed by 14 CFR.
Instrument Flight Procedure Validation (IFPV) of Satellite-based Instrument Flight Procedures (IFP)
This advisory circular (AC) provides guidance for conducting Instrument Flight Procedure Validation (IFPV) of Satellite-Based Performance-Based Navigation (PBN) Instrument Flight Procedures (IFP) for both fixed-wing and helicopter aircraft. This also addresses validation of helicopter wide area augmentation system (WAAS) special IFP. This document supplements and does not change the requirements of FAA Order 8200.1, United States Standard Flight Inspection Manual. It describes ground validation, preflight validation (including simulator evaluation and obstacle assessment), and flight validation.
Aircraft Wake Turbulence
This advisory circular (AC) presents basic information on wake vortex behavior, alerts pilots to the hazards of aircraft wake turbulence, and recommends operational procedures to avoid wake turbulence encounters.
Automatic Dependent Surveillance-Broadcast Operations
The Federal Aviation Administration (FAA) has issued a new rule contained in Title 14 of the Code of Federal Regulations (14 CFR) part 91, §§ 91.225 and 91.227. This rule requires Automatic Dependent Surveillance-Broadcast (ADS-B) Out performance when operating in designated classes of airspace within the U.S. National Airspace System (NAS) after January 1, 2020. This advisory circular (AC) provides users of the NAS guidance on a means of conducting flight operations in accordance with §§ 91.225 and 91.227. The appendices in this AC provide guidance for additional operations enabled by ADS-B to include ADS-B In.
