Reliability and Maintainability of Aircraft (FSI-OSD-A)

Academic year 2020/2021
Supervisor: doc. Ing. Jiří Hlinka, Ph.D.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
The main course objective is to give students an introduction to procedures and methods used to ensure safety and dependability of an aircraft (and other industrial products).
Learning outcomes and competences:
The course provides students with basic knowledge of the area of dependability (reliability and maintainability) of aircraft. This includes information about modern methods and procedures for safety assessment (reliability analyses, etc) and information about international standards and airworthiness requirements.
Prerequisites:
Students are expected to have mastered the basics in statistics and probability calculations and they have at least basic knowledge of aerospace engineering (structure and systems of an aircraft).
Course contents:
The course offers a general overview on modern methods of safety and reliability assessment with special attention on an aircraft and aircraft systems. This includes reliability analyses, calculations, estimates and test methods. Emphasis is put on the main properties of dependability: reliability, availability and safety.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
To meet requirements for the course-unit credit award it is necessary to attend 80% of compulsory seminars, to hand in student works and meet requirements of 2 written tests.
Controlled participation in lessons:
The attendance at seminars is compulsory. In case of justified absence, the seminar may be compensated by an individual assignment.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Exercise  13 × 1 hrs. compulsory
