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.

Electro-Pneumatic systems exhibit highly nonlinear characteristics due to air compressibility, the presence of friction and the nonlinearities of control valves. Monitoring by acquiring the system's transfer function accurately can be difficult for nonlinear systems. This paper outlines a new idea that one can deal with the electro-pneumatic system as a black box, and using a multivariate technique called principal component analysis (PCA) and projection to latent structure discriminant analysis (PLSDA) to provide robust information about the system's condition. The monitoring system has been experimentally validated for an electro-pneumatic printing machine system using vibration, pressure and displacement sensory data integration using PCA-PLSDA algorithm. Experiments were conducted under two pressures for three artificially conditions: normal, throttled, and leaking system.

A review of the main operational practices related to CDO (Continuous Descent Operations) with relevance for noise and emissions reduction, shows the importance of working in a team when implementing new operational practices, as well as the need to access data either through FDR (flight data recorder) or from measurements. - The example selected explains the difficulties one can have to extract FDR data. ...Key to assessment is the supply of Flight Data Recorder output, the minor cost of provision of this could be offset against the potentially massive fuel benefits that would accrue to airlines if harmonized CDA can be promulgated.

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 liquid behavior was recorded on video tape and acceleration data was recorded on a data recorder. As a result liquid-gas separation was perfectly achieved in any phase of the parabolic flight, namely under the high-G to micro-G environment, and it was verified that the functional model has the required function.

This document provides aircraft installation requirements for a Low Frequency Underwater Locator Beacon (LF-ULB) transmitting on a frequency of 8.8 kHz. ICAO Annex 6 Amendment 36, states that a LF-ULB shall be installed on all aircraft with a maximum certified take-off mass of over 27,000 kg, operating over water at particular distances to land suitable for making an emergency landing. ICAO Annex 6 Amendment 36 further states that an LF-ULB shall be installed by January 1, 2018.
