This article highlights the specifics of on-board recorders among the various systems found on aircraft. Attention is drawn to the legal and technical compliance requirements concerning modern on-board recorders. Reference is also made to certain aspects of recording methods and data security. Furthermore, the paper especially focuses on the process of measuring a parameter, indicating the basic criteria regarding the accuracy of the measurement. In addition, the role of two essential elements in the measuring chain is discussed: the feeder as a parameter measurer and the transformation system, i.e., AC converter.

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.

This article attempts to provide a synthesis of basic directions indispensable to accurately collecting evidence after an aviation accident. The proper collection procedure ensures the avoidance of the loss of evidence critical for an investigation carried out by law enforcement agencies and/or the criminal justice system, which includes the participation of aviation expert investigators. Proper and complete evidence is also used to define the cause of the accident in the proceedings conducted by Państwowa Komisja Badania Wypadków Lotniczych (State Committee for Aviation Incidents Investigation, The State Committee for Aviation Incidents Investigation, hereafter referred to as the PKBWL). The methodology of securing evidence refers to the evidence collected at the scene of an accident right after its occurrence, and also to the evidence collected at other sites. It also includes, within its scope, additional materials that are essential to furthering the investigation process, although their collection does not require any urgent action. Furthermore, the article explains the meaning of particular pieces of evidence and their possible relevance to the investigation process.
