Available flight recorder data are used to tune the model and reconstruct the accident. Then the model is used for in-depth examination of the accident’s “neighborhood” in autonomous “what-if” simulation experiments under actual and hypothetical conditions.

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.

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.

The TIMED spacecraft is implementing an Integrated Electronics Module (IEM) that contains several different spacecraft subsystems, like C&DH, S-band receiver and transmitter, solid-state recorder and more. The combination of all these subsystems into one box, normally packaged in separate card cages, has resulted in some challenging thermal design problems.

This checklist is to be used by project personnel to assure that factors required for adequate system electromagnetic compatibility are considered and incorporated into a program. It provides a ready reference of EMC management and documentation requirements for a particular program from preproposal thru acquisition. When considered with individual equipments comprising the system and the electromagnetic operational environment in which the system will operate, the checklist will aid in the preparation of an EMC analysis. The analysis will facilitate the development of system-dependent EMC criteria and detailed system, subsystem, and equipment design requirements ensuring electromagnetic compatibility.

Well sealed in flight The introduction of fly-by-wire and electrohydraostatic actuators has changed the design of hydraulic flight controls.

This standard describes the basic requirements for an AHRS specifically designed for installation in commercial transport aircraft. The AHRS is an attitude and heading sensor that provides outputs in digital form for guidance and display. The AHRS replaces the traditional vertical and directional gyros.

This standard provides general and specific guidance for the development of a Portable Data Loader (PDL) for carry-on application and an Airborne Data Loader (ADL) for on-board the airplane. It specifies use of a 3.5 inch floppy disk to upload and download of data and operational programs using an ARINC 429 data bus connected to avionics computers.
