Reliability and Maintainability of Aircraft
FSI-OSDAcad. year: 2018/2019
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.
Learning outcomes of the course unit
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.
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).

Planned learning activities and teaching methods
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.
Language of instruction
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).
Specification of controlled education, way of implementation and compensation for absences
The attendance at seminars is compulsory. In case of justified absence, the seminar may be compensated by an individual assignment.
