The new flight recorders device will meet an upcoming 2021 European Aviation Safety Agency (EASA) mandate requiring aircraft to store a minimum of 25 hours of voice recordings.

Curtiss-Wright Corporation’s Fortress line of combined cockpit voice recorders (CVRs) and flight data recorders (FDRs) are now have European Technical Standard Order (ETSO) approval.

This SAE Aerospace Information Report (AIR) summarizes prior empirical findings (AIAA 2018-3991; Chati, 2018) to recommend a modified baseline fuel flow rate model for jet-powered commercial aircraft during taxi operations on the airport surface that better reflects operational values. Existing standard modeling approaches are found to significantly overestimate the taxi fuel flow rate; therefore, a modified multiplicative factor is recommended to be applied to these existing approaches to make them more accurate. Results from the analysis of operational flight data are reported, which form the basis for the modeling enhancements being recommended.

The difficulty in locating crash sites has prompted international efforts for alternatives to quickly recover flight data. This document describes the technical requirements and architectural options for the Timely Recovery of Flight Data (TRFD) in commercial aircraft. ICAO and individual Civil Aviation Authorities (CAAs) levy these requirements. The ICAO Standards and Recommended Practices (SARPs) and CAA regulations cover both aircraft-level and on-ground systems. This report also documents additional system-level requirements derived from the evaluation of ICAO, CAA, and relevant industry documents and potential TRFD system architectures. It describes two TRFD architectures in the context of a common architectural framework and identifies requirements. This report also discusses implementation recommendations from an airplane-level perspective.

This document sets forth the characteristics of an Aircraft Interface Device (AID) intended for installation in commercial aircraft. The intent of the document is to provide general and specific design guidance for the development of an AID for use in retrofit applications associated with aircraft typically developed between the mid-1970s through the 1990s, that primarily utilize ARINC 700 series avionics, and that interface with the aircraft via ARINC 429 and ARINC 717 unidirectional buses and Hi/Lo discrete signals. This document describes the desired operational capability of the AID and the standards necessary to ensure interchangeability.

This standard sets forth design guidance and airplane interfaces for the development and installation of a PVS in commercial transport aircraft. Basic function of the PVS is to display projected television images to each passenger.

This standard sets forth characteristics of a new-generation HF/SSB System intended for installation in all types of commercial transport aircraft. Covers requirements for airborne transmitter-receiver equipment capable of transmitting and receiving HF radio intelligence.

This standard defines accuracy and reliability targets for fuel quantity measuring systems installed on commercial aircraft. It describes fuel quantity system components and design techniques that will contribute to safe and reliable operation. System design goals and installation practices are described. A report of a worldwide fuel survey is included.

The purpose of this document is to facilitate an understanding of aircraft information security and to develop aircraft information security operational concepts. This common understanding is important since a number of subcommittees and working groups within the aeronautical industry are considering aircraft information security. This document also provides an aircraft information security process framework relating to airline operational needs that, when implemented by an airline and its suppliers, will enable the safe and secure dispatch of the aircraft in a timely manner. This framework facilitates development of cost-effective aircraft information security and provides a common language for understanding security needs.

This ARP provides an insight into how to approach a cost benefit analysis (CBA) to determine the return on investment (ROI) that would result from implementing a propulsion Prognostics and Health Management (PHM) system on an air vehicle. It describes the complexity of features that can be considered in the analysis, the different tools and approaches for conducting a CBA and differentiates between military and commercial applications. This document is intended to help those who might not necessarily have a deep technical understanding or familiarity with PHM systems but want to either quantify or understand the economic benefits (i.e., the value proposition) that a PHM system could provide.
