21-48 AIR-100 Using Electronic Modeling Systems as Primary Type Design Data

This AC provides information and guidance on developing procedures for using electronic modeling systems in design, manufacture, installation, and inspection processes.  It applies to applicants for Type Certificates (TCs), Amended Type Certificate (ATCs), Supplemental Type Certificates (STCs), Parts Manufacturer Approval (PMA), Technical Standard Order Authorizations (TSOA), major alterations, and major repairs.  In this AC, we explain how you can submit a proposal to use electronic modeling system data instead of (or in addition to) traditional paper format for the technical data required for initial and post certification activities.  We identify the minimum criteria for using electronic type design data, and include requirements for how to access and present the data.  In this AC, we define an “electronic modeling system” as a three?dimensional (3-D) modeling system.

 For Federal Aviation Administration (FAA) certification applicants, this AC mirrors our procedures in Order 8000.79, Use of Electronic Technology and Storage of Data, and Guide FAA-IR-01?01A, Aircraft Certification Guide for the Use of Electronic Technology and Alternative Methods of Storing Information. This AC must be used in conjunction with Order 8000.79 and Guide FAA-IR-01-01A.

 This AC is not mandatory and does not constitute a regulation.  We describe acceptable means, though it is not the only means, for using electronic modeling systems in design, manufacture, installation, and inspection processes.  If you use the means described in this AC, you must follow it in its entirety

150/5370-11B AAS-100 Use of Nondestructive Testing in the Evaluation of Airport Pavements

Focuses on nondestructive testing (NDT) equipment that measures pavement surface deflections after applying a static or dynamic load to the pavement. It also briefly introduces other types of nondestructive measuring equipment to illustrate how supplementing NDT data with other test data may improve the quality and reliability of the pavement evaluation. This version updates Chapter 8, NDT-Based Evaluation and Design Updates, to reflect the requirements of the pavement design program FAARFIELD rather than the previous design program LEDFAA.

20-77A AFS-350 Use of Manufacturers' Maintenance Manuals
Informs owners and operators about the usefulness of manufacturers’ maintenance manuals for servicing, repairing, and maintaining aircraft, engines and propellers.
00-63A AFS-400 Use of Cockpit Displays of Digital Weather and Aeronautical Information

This advisory circular (AC) provides guidance to flightcrew members and other airmen on the use of data link to access Flight Information Services (FIS). This AC addresses both the Federal Aviation Administration (FAA) FIS Broadcast (FIS-B) provided through the Automatic Dependent Surveillance – Broadcast (ADS-B) Universal Access Transceiver (UAT) network and non-FAA FIS systems provided through commercial data link services.

a. Flight Information Services (FIS). FIS is a service that provides Meteorological Information (METI) and Aeronautical Information (AI) to enhance pilot awareness of weather and/or airspace constraints while providing information for decision support tools and improving safety. METI and AI data link services enable flightcrews to support the Next Generation Air Transportation System (NextGen) concepts of information sharing and provide airmen with a common operating picture necessary to support the evolving global Air Traffic Management (ATM) concepts.

b. Advantages of FIS METI and AI. FIS of METI and AI can augment pilot voice communications with Flight Service Stations (FSS), other air traffic control (ATC) facilities, airline dispatch centers, flight following facilities or other Operation Control Centers (OCC), typically referred to as System Operations Control (SOC). In addition, Internet connectivity provides the capability for Baseline Synchronization Services (BSS) to be utilized to update the aircraft’s navigational and other databases prior to flight.

91-78 AFS-800 Use of Class 1 or Class 2 Electronic Flight Bag (EFB)
This advisory circular (AC) provides aircraft owners, operators, and pilots operating aircraft under Title 14 of the Code of Federal Regulations (14 CFR) part 91, with information for removal of paper aeronautical charts and other documentation from the cockpit through the use of either portable or installed cockpit displays (electronic flight bags (EFB).
91-62A AIR-120 Use of Child Seats in Aircraft
Provides information to assist the public in the proper use of child seats aboard aircraft and provides precautions so all occupants are able to exit rapidly from aircraft during emergencies.
120-87B AFS-200 Use of Child Restraint Systems on Aircraft

This advisory circular (AC) provides information and practices regarding the use of child restraint systems (CRS) on aircraft. We intend for operators to use this as a resource during the development, implementation, and revision of an air carrier’s standard operating procedures (SOP) and training programs regarding the use of CRSs. This AC is one of several Federal Aviation Administration (FAA) initiatives designed to address safety concerns of the National Transportation Safety Board (NTSB). In addition, it is a part of the FAA’s ongoing commitment to educate and inform aircraft operators, crewmembers, and airline passengers regarding the use of CRSs on aircraft in order to encourage and increase the use of approved CRSs. For more information, see the following FAA Web site:
