Course detail

Reliability and Maintainability of Aircraft

FSI-OSD-AAcad. year: 2023/2024

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.

Language of instruction


Number of ECTS credits


Mode of study

Not applicable.

Offered to foreign students

The home faculty only

Entry knowledge

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).

Rules for evaluation and completion of the course

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.
The attendance at seminars is compulsory. In case of justified absence, the seminar may be compensated by an individual assignment.


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).
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.
