Objectives and Contextualisation

It is widely known by professionals in the industrial sector that the incorporation of Reliability, Availability and Maintainability characteristics in the design stage of a system and its components is the best way to ensure that this system has an adequate long-term cost-effectiveness ratio. Under this motivation, this subject aims to study the main theoretical foundations associated with the concepts of reliability, availability and maintainability, and their relationship with the effectiveness of the systems.Likewise, the concept of airworthiness and the European EASA regulations will be studied in what refers to Maintenance Centers Part 145 and Airworthiness Organizations (CAMO). Additionally, its application will be applied to practical cases.

Competences

  • Apply specific software for solving problems in the aeronautical sector.
  • Communication.
  • Identify, develop and maintain the necessary resources to meet the tactical and operative needs inherent to air transport activities.
  • Personal attitude.
  • Personal work habits.
  • Thinking skills.
  • Use knowledge of the fundamental principles of mathematics, economics, information technologies and psychology of organisations and work to understand, develop and evaluate the management processes of the different systems in the aeronautical sector.
  • Work in teams.

Learning Outcomes

  1. Accept and respect the role of the various team members and the different levels of dependence within the team.
  2. Carry out system-reliability studies.
  3. Communicate knowledge and findings efficiently, both orally and in writing, both in professional situations and with a non-expert audience.
  4. Critically assess the work done.
  5. Develop critical thought and reasoning.
  6. Develop curiosity and creativity.

Methodology

Teaching will be offered on campus or in an on-campus and remote hybrid format depending on the number of students per group and the size of the rooms at 50% capacity.

 

The methodology of the subject is based on a combination of theoretical and practical classes. During the theoretical classes, the professor will present the fundamental concepts of the assignment, whereas, in the practical classes, students will be those who, working individually or in small groups, will carry out the activities and exercises proposed during the course.

Will be encouraged to work in collaborative groups, the use of ICTs, and also the use of specialized software (eg: R, MINITAB, Excel, SREMS, SAEDES, etc.).

 

The proposed teaching methodology may undergo some modifications according to the restrictions imposed by the health authorities on on-campus courses.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
