AIR1873A
This Aerospace Information Report (AIR) describes a Limited Engine Monitoring System that can be used by the flight crew or the maintenance staff, or both, to monitor the health of gas turbine engines in aircraft. This AIR considers monitoring of gas path performance and mechanical parameters, and systems such as low cycle fatigue counters and engine history recorders. It also considers typical measurement system accuracies and their impact. This AIR is intended as a technical guide. It is not intended to be used as a legal document or standard. AIR 1873 supplements ARP 1587, Aircraft Gas Turbine Engine Monitoring System Guide.

An industry survey has been completed to determine the incidence of jam and excessive backlash in rotary and linear mechanical actuators subject to "primary flight control like" duty cycles. The data is valuable for understanding how existing mechanical actuators behave in service, identifying areas for potential improvement and possibly being used as a reference to support future primary flight control system trade-off studies.

Abstract Reliability engineering methods are used to assess risk and eliminate hazards by estimation, elimination, and management of risks of failures. The ISO 26262 functional safety standard gives detailed guidance on reliability engineering methods like Failure Mode and Effect Analysis (FMEA) [7], Fault Tree Analysis (FTA) [8] [2], and etc. While, there are many methods available for reliability engineering; no single method is foolproof for securing safety by eliminating hazards completely. Out of these methods, FMEA is widely being used as an integral part of the product development life cycle [10]. In this method, failure modes of individual components are analyzed considering one failure at a time. FMEA is an efficient method for analyzing failures in simple systems. For complex systems, FMEA becomes impractical. It is also difficult to consider variables in FMEA.

Abstract This study evaluated the performance of heavy vehicle crash avoidance systems (CASs) by collecting naturalistic driving data from 150 truck tractors equipped with Meritor WABCO OnGuardTM or Bendix® Wingman® AdvancedTM products. These CASs provide drivers with audio-visual alerts of potential conflicts, and can apply automatic braking to mitigate or prevent a potential collision. Each truck tractor participated for up to one year between 2013 and 2015. Videos of the forward roadway and drivers’ faces were collected along with vehicle network data while drivers performed their normal duties on revenue-producing routes. The study evaluated the performance of CAS activations by classifying them into three categories based on whether a valid object was being tracked and whether drivers needed to react immediately.

The ability to successfully predict industrial product performance during service life provides benefits for producers and users. This book addresses methods to improve product quality, reliability, and durability during the product life cycle, along with methods to avoid costs that can negatively impact profitability plans. The methods presented can be applied to reducing risk in the research and design processes and integration with manufacturing methods to successfully predict product performance. This approach incorporates components that are based on simulations in the laboratory. The results are combined with in-field testing to determine degradation parameters. These approaches result in improvements to product quality, performance, safety, profitability, and customer satisfaction.
