Computer software in civil aircraft

Airborne software is only one element of an aircraft´s systems, and only one element of the aviation software environment. Consequently, it cannot be considered in isolation. Airborne software, is used where its benefits outweigh its advantages, notably to improve human factors, which are involved in most aircraft accidents. The timescales extend over many decades, and involve a large number of supplies. Airborne software is produced in accordance with uniquely severe aviation standards. These standards ensure that very great efforts are made to aim at freedom from errors, but freedom from faults is not assumed, and thus fault consequences are assessed and dealt with on a continuing basis. A number of powerful tools have been developed to facilitate software development and compliance with these standards
