For some indicators control levels are defined in relation to an average value of a parameter. If it is too long, some failures are going to be missed. What is industry 4.0 and how will it affect our factories in the short term? INTRODUCTION In the aviation industry maintenance is considered as a key in helping airlines to succeed. For mechanical components, this means that sensors permanently measuring certain parameters of a system are installed, and on which bases technical health may be estimated. ernest.bazijanac@fpz.hr, Mech B.Sc., senior lecturer nur – is the total number of unscheduled component removals in the observed period nks – is the number of components in a system h – is the total aircraft flight hours in the observed period. Pun intended. When it comes to the recycling of industrial plastic packaging, however, the situation is different, and there are hardly any systems in place for this purpose. (d) Reliability program. Corrective actions can be taken immediately, and the outcome of these actions monitored easily. Operational performance (or operational reliability) is about running an airline like a well-oiled machine. Aircraft systems are monitored according to ATA 100 specification. The “Iceberg” of parameters for monitoring aircraft reliability.  announced that it has entered into separate agreements to further integrate FDT and FDI technologies into EtherNet/IP™. To provide a reliability program which improves aircraft, power plants, and/or systems reliability through data collection, analysis, corrective action, and follow-up. Aircraft fleet despatch reliability. The total possible capacity of the fleet of one aircraft type expressed in hours is: hm – is the number of hours in the period observed, e.g. Kiilto brought together enthusiastic partners to pilot the recovery of HDPE packaging during the year with eight customer companies. Also in this case this indicator is in practice presented in somehow modified form and called “the system reliability rate”, and it shows an average number of unscheduled removals of particular components of a system to a thousand hours of flight. Figure 5. All contemporary transport aircraft are equipped with an onboard maintenance system. The main purpose of such reliability program is to ensure that the aircraft maintenance program tasks are effective and that the periodic tasks are performed adequately (see Acceptable Means of Compliance to EASA Part-M). In the first part of the article the methodology of calculating the parameters for aircraft reliability monitoring in operation and the interpretation of monitoring results are presented. Escalation, deletion or addition of a maintenance task may be the result of a reliability program. Typically, air dryers have an average service interval of fewer than two years. For monitoring the aircraft reliability technical data obtained in operation as well as regular and extra inspections of an aircraft, its systems and components are evidenced. »»References [1] Bazijanac, E.: Aircrafts Operation and Maintenance, Theoretical Fundamentals, Faculty of Transport and Traffic Sciences, Zagreb, 2007. The air carrier will monitor the reliability of aircraft in operation and send the collected data to the aircraft manufacturer. It’s about reducing involuntary … Also, an air carrier is obliged to deliver reports on reliability monitoring to aviation authorities as a proof that aircraft structure, power plant, its components and other systems are capable of achieving and maintaining reliability levels high enough, which is the basis for safety of carrying out aircraft operations. According to this criterion the upper control level (GKG) and lower control level (DKG) equals: GKG = x + k ⋅ σ (6) The programme of reliability monitoring serves as a supplement to the standard maintenance programme of a particular aircraft in order to maintain its continuous airworthiness. DKG = x − k ⋅ σ (7) Martin Krill has been working for Hager Unternehmensberatung for nearly 20 years. No need for manual reporting. It’s about on-time performance and completion rates. The data collected in that way are the basis for each reliability monitoring and the conclusions obtained and based on them depend on their accuracy and so the total result. The delay and cancellations rate may also be classified by systems according to ATA specification, enabling the monitoring of components and systems most often failing, Figures 6 and 7. 2. If you are having any questions, please feel free to ask.

Aircraft reliability programs are essential to ensure safety and dependability. For measuring power system reliability, the technology enabling these data to be automatically collected during flight and stored in a portable medium is used. AC 42-3(0): Reliability Programs 4 September 2012 6.3 The ASETPA reliability program requirements are as recommended by ICAO in Annex 6 to the Convention on International Civil Aviation.A copy of the … The systematized and analysed results of one aircraft type manufacturer are presented below. Recycling plastic consumer packaging waste has long been easy and is a well-established practice for most consumers. The aim is to get the data on the average number of available aircraft in the period observed. The failures or breakdowns of a particular system are diagnosed and memorized by CFDS (Centralized Fault Display System). Black Swans in Maintenance and Industrial AI: Predicting the Unpredictable? Figure 1. Aircraft structural reliability is obtained by the methods of non-destructive testing – NDT. 269–277 [4] Marušić, Ž.; Alfirević, I.; Pita, O.: Methods of Increasing Reliability and Aircraft Maintenance System, Tehnički vjesnik, 14 No 3 i 4, 2007, pp. Reliability Analysis - 5 Things Excel can't do. After this training, the participants must be able to demonstrate an understanding of reliability programmes necessary for the maintenance programme for MSG-3 aircraft. The failure models of Type III and Type IV totaled 45 items, all of which have been written in the maintenance and using manual attached to the equipment. Sustainability transformation: Are you ready for the change? Chapter 19 text ; 2 Reliability. The analysis is carried out on a computer in a technical base. Sofema Aviation Services currently offers 10 different reliability related training courses – Organisations which focus on and employ the data generated by the reliability program in the most effective way see a real and meaningful return on the investment. The results obtained by monitoring reliability in operation may serve as a basis for supplementing or modifying the aircraft maintenance programme; such changes would indicate the malfunction of components or systems manifesting lacks and the need for early control, or replacement during utilization. Maintworld - Building International Connections in Industrial Maintenance. “the black box” is an obligatory device in an aircraft. The Reliability Report is required by aviation authorities from every operator. For example, “the level of reliability on the basis of pilot reports in the observed period in relation to a hundred take-offs” can be defined: np – is the number of pilot reports in the observed period. It stores aircraft parameters serving also for the analysis of a possible incident. Time to Invest in Europe’s Water Infrastructure, Tips on How to Accelerate the Circular Economy, Everything Should Be Smart - But It Must Also Be Safe, 5 Important Maintenance Metrics and How To Use Them. The histogram in Figure 8 presents 10 components which, after processing of all the data received, proved as being replaced most often. Four times a year, on the basis of the collected data received from air carriers, the manufacturer issues a report on the reliability for a certain aircraft type available to all air carriers having that type of aircraft in their fleet. To further improve these programs, Boeing … The data presented are the result of monitoring the reliability of a fleet of 34 air carriers in one year, whose total flight hours amounted to 8 072 951 flight hours and 7 173 857 flight cycles. To assess reliability the malfunction of particular aircraft systems is monitored, due to which some components are to be removed in an unscheduled manner. For monitoring the aircraft reliability technical data obtained in operation as well as regular and extra inspections of an aircraft, its systems and components are evidenced. On the basis of these data the manufacturer may identify the systems and/or components due to which problems in aircraft operation most often arise. The Avilytics Aircraft Reliability Management suite displays the entire scope of an aircraft reliability program in several dashboards in real-time, eliminating the need for manual reporting. Despatch reliability is presented by graph in Figure 4, while Figure 5 presents the delay rate due to technical reasons and cancelled flights.
