This article is dealing with airline industry standards regarding reliability reporting and with practical aspects of reliability program deployment within an operator’s organization. Reliability program is a tool for monitoring the effectiveness of aircraft maintenance program. Apart from being an effective tool for maintenance program development, the reliability program can bring to light flaws in aircraft design, discrepant operational procedures, discrepancies in line and base maintenance. Reliability program is also considered to provide very valuable means for achieving better operational performance (through decreased maintenance-related problems in operation) and increased flight safety. For this reason, reliability programs are mandated by the regulations for all commercial operators. Even though there is a general industry standard regarding maintenance reliability programs, it still has to be customized and optimized by each operator in order to gain the most out of it. Organizational procedures will vary significantly from one operator to another, reflecting the size and structure of the monitored fleet, size of the operator and its engineering power. As maintenance reliability program involves the application of statistic methods in finding systematic negative trends, the bigger the size of the fleet, the more accurate and reliable results can be achieved. This work is outlining the existing airline industry standards and good practice in carrying out maintenance reliability program. KEY WORDS: aircraft maintenance program, maintenance reliability program, flight safety, small airline operator

Standards And Guidelines

The current best practice of providing reliable systems is to embody the development process in recent industry standards and guidelines, such as IEC61508 for safety and ISO9001 for quality assurance. These standards are generic, but every application is different because of the differences in project details. While current workflow systems have been used successfully in managing “administrative” process for some time, current products lack the ability to ensure that a process is planned and performed such that it complies with an industry standard that is necessary to support particular engineering processes. This chapter presents a Compliance Flow Workflow System for managing processes. Model-based reasoning is used to identify the compliance errors of a process by matching it against the model of standards used. Some examples drawing on a draft version of IEC61508 are used to illustrate the mechanism of modeling and compliance checks.

Standard Regulation

To maintain flight safety, all transport aircraft designs should satisfy airworthiness standard regulation. One fundamental issue of the aircraft design that relates directly to flight safety as well as commercial aspect of the aircraft is on the evaluation of the maximum speed within the designated flight envelope. In the present work, a study is performed to evaluate the negative altitude requirement related to aeroelastic instability analysis as one requirement that should be fulfilled to design the maximum speed. An analytical derivation to obtain the negative altitude is performed based on the airworthiness requirement that a transport airplane must be designed to be free from aeroelastic instability within the flight envelope encompassed by the dive speed or dive Mach number versus altitude envelope enlarged at all points by an increase of 15% in equivalent airspeed at both constant Mach number and constant altitude. To take into account variation in atmospheric condition as function of altitude, the international standard regulation is used as referenced. The analysis result shows that a single negative altitude can be obtained using these criteria regardless of the dive speed or dive Mach number. A further discussion on the application of the negative altitude concept to UAV (Unmanned Aerial Vehicle), in relation to UAV Standard Airworthiness Requirement STANAG 4671, is presented.

A key element of exploitation processes constitutes maintenance operations and tasks. While being conducted in the proper way, they have a crucial effect on achieving the assumed by aircraft designer and operator goals. Properly conducted maintenance operations allow to meet all the technical objects readiness requirements as well as to achieve desired acceptable risk level. Maintenance system effectiveness might be generally a crucial task for company or entity responsible for the maintenance. In this context, particularly relevant become technical object maintenance procedures and tasks developed by their manufacturers. Experience of the article authors quite early shows the need of the mainte-nance programmes modification. Aircraft manufacturers usually are not so eager to develop and implement mainte-nance programme modifications. Presented situation is very much the case in aviation transport. This was the reason why authors of this article decided to prepare and develop this elaboration which might constitute the assistance and supports complex technical objects users in maintenance decision. The main purpose of this article is to present maintenance decisions’ supporting method for the aircraft operators. This article provides guidelines which include a description of risk in the context of aviation maintenance and introduction of some methodologies, tools and criteria that support identification, analysis and evaluation of risk. Authors included idea, how the aircraft preventive maintenance could be used to mitigate aircraft failure risk during flight operations. It also shows how to adopt and develop effective maintenance program using tools for adequate risk analysis, optimal interval assignments, and selection of the most effective maintenance task. Authors presented methodology and de-scribed steps of the logic diagram analysis for the aircraft systems and their components, in order to manage and adopt aircraft maintenance program to fulfil aircraft airworthiness requirements and operational availability. The whole methodology was described on the basis of the F 16 aircraft maintenance system and with reference to the maintenance data. This article might also constitute an introduction to the aircraft maintenance programme development method.

Subject Outlook for US investigations into airlines collusion. Significance Three carriers, United, American Airlines and Delta, account for 80% of US domestic air travel; Southwest, the leading low cost carrier (LCC) takes much of the remainder. The Department of Justice (DoJ) and the Department of Transportation (DoT) have both launched major investigations into the pricing practices of the airlines. Both regulatory moves imply that the rationalisation of the US airline industry has left passengers vulnerable to predatory behaviour, which would worsen if the US market were further closed to foreign competition. Impacts Low oil prices may provide a long-term boost to profits if airlines move to lock in new hedges. However, manufacturers will be hit hard by an economic slowdown in China, home of two of the largest airlines by fleet size. Increasing wages elsewhere in the US economy will add further pressure to airline labour costs.

This chapter introduces an ontology-based framework for automated construction of complex interactive data mining workflows as a means of improving productivity of Grid-enabled data exploration systems. The authors first characterize existing manual and automated workflow composition approaches and then present their solution called GridMiner Assistant (GMA), which addresses the whole life cycle of the knowledge discovery process. GMA is specified in the OWL language and is being developed around a novel data mining ontology, which is based on concepts of industry standards like the predictive model markup language, cross industry standard process for data mining, and Java data mining API. The ontology introduces basic data mining concepts like data mining elements, tasks, services, and so forth. In addition, conceptual and implementation architectures of the framework are presented and its application to an example taken from the medical domain is illustrated. The authors hope that the further research and development of this framework can lead to productivity improvements, which can have significant impact on many real-life spheres. For example, it can be a crucial factor in achievement of scientific discoveries, optimal treatment of patients, productive decision making, cutting costs, and so forth.

Fusarium head blight (FHB) causes yield loss, quality reduction, and grain mycotoxin accumulations. A novel pydiflumetofen-containing fungicide, Miravis Ace, was recently registered in North America. The main objective of this study was to assess the efficacies of Miravis Ace and the timing of application alongside industry standard triazole fungicides (Prosaro, Caramba, Proline and Folicur) on suppressing FHB, reducing mycotoxins and improving wheat agronomic performance. The assessment was conducted across six natural environments on commercial farm fields and in two artificially inoculated-misted environments. All environments included 5 fungicides (Miravis Ace and the four triazole fungicides) and 3 application timings (Zadoks GS 59, 65, 69-71). Additionally, for the ZGS 65 timing, the experiment in the natural environment included a quinone outside inhibitor (QoI) fungicide pyraclostrobin (Headline). In general, Miravis Ace tended to be more effective on FHB suppression than the triazole fungicides across all environments. However, any biological differences tended to be statistically non-significant, likely because of a lack of statistical power. Miravis Ace reduced total deoxynivalenol (DON) concentration by 52-73% compared to the non-treated control. If applied at ZGS 59-65, Miravis Ace was more effective in increasing yield and test weight than the triazoles tested. Across fungicides, applications made at ZGS 65 were most effective in FHB suppression compared to earlier or later application timings. There was no evidence that pyraclostrobin increased mycotoxin concentrations. Overall, compared to the triazole fungicides, the novel pydiflumetofen-containing fungicide tended to have lower FHB suppression and mycotoxins, higher grain yield and test weight, and higher harvest moisture, but differences were not always statistically significant. Because the main active ingredient in Miravis Ace has a different mode of action than the triazoles, we speculate that this fungicide will be competitive with industry standards, and benefit strategies for fungicide resistance management.
