In recent years, much attention has been paid to the recording of flight data in order to provide objective information concerning routine and emergency in-flight situations. The data recorded can be used for assessing the air mission execution by the pilot and flight safety breaches, for specifying some damage to the equipment, and for preventing faulty equipment from being used in flights. Flight data recorders (FDRs) are commonly known as “black boxes”. This article presents issues related to flight data acquisition and preparing the data for later use, as well as their impact on flight safety. The systems recording and processing selected parameters not only enable ongoing diagnostics, but also make it possible to predict the period of further reliable operations and to analyse the causes that led to possible damage. In addition to improving economic indicators of the aircraft operation, flight safety is improved. Obviously, the article will only discuss certain ways of enhancing safety by applying the processing of data obtained from FDRs. Nevertheless, I believe it will offer an overall view of how important it is to collect, process and properly analyse such data for diagnostics, prediction and flight safety.

Objectives. Musculoskeletal disorders (MSDs) are prevalent among airline baggage handlers due to manual materials handling. In this study, the Nordic musculoskeletal questionnaire (NMQ), the revised National Institute for Occupational Safety and Health (NIOSH) lifting equation, and the University of Michigan 3D Static Strength Prediction Program™ (3DSSPP) were used to analyze MSDs among baggage handlers. Methods. The NMQ was filled out by 209 baggage handlers and 46 arbitrarily selected baggage handlers were evaluated using the NIOSH method and 3DSSPP. Results. The obtained results showed that the most common MSDs occurred in the lower back region. The next risky regions included knees, neck, and upper back, respectively. The NIOSH results confirmed that the subjects lifted loads heavier than the permitted limit and their lifting postures were inappropriate. The results of the 3DSSPP also indicated that compression forces exceeded the NIOSH limit in these awkward postures. Conclusions. Relying on this study, holding compulsory ergonomic lifting training courses could be proposed for workers and regulations adjusting an upper limit for maximum baggage weight must be also enacted in order to improve occupational health and prevent the prevalence of increasing MSDs.
