Course detail

Reliability and Maintainability of Aircraft

FSI-OSD-AAcad. year: 2022/2023

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.

Offered to foreign students

The home faculty only

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.

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).

Co-requisites

Not applicable.

Recommended optional programme components

Aims

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.
