Opis:
One of the problems becoming increasingly important in the exploitation process of each technical object is effectiveness expressed as a ratio of the value of obtained results to the related expenditure. There are several criteria to evaluate the effectiveness of the exploitation process. However, in their selection, it is necessary to take into account the characteristics not only connected with a concrete object or system, but also with a model of its use. In civil aviation, especially in case of airlines and various kinds of service companies, the effectiveness of exploitation system of the aircraft fleet is assessed primarily in economic terms. However, in military aviation, due to its characteristics, slightly different criteria must be applied. In practice, the effectiveness of such systems is usually assessed based on the index of technical exploitation readiness, which specifies the system readiness to execute the agreed tasks within predetermined time. This paper presents selected aspects of technical readiness related to the exploitation system of trainer aircraft in military aviation. The issues connected with determining the total flying time, conducted within the framework of the training cycle, are discussed. The factors affecting the state of technical readiness related to the exploitation system of the aviation technology as well as methods for determining the required number of aircraft to perform the tasks planned for a given period and the index of available service life resources.

Opis:
The efficiency of the aircraft exploitation process is a problem, to which more and more attention is paid not only in the commercial aviation, but also in the military one. One of the factors, which have a direct impact on its level, is the operated aircraft or helicopter technical readiness that is the ability of airworthiness when there is a need to use them in order to perform specific aviation tasks. In turn, the aircraft technical readiness level is affected by a number of factors, the most important of which include its characteristics, technical service system and logistical security system. This paper is devoted to the issue connected with the aircraft technical readiness assessment as well as identification of factors, which have an impact on its level, and also their impact level analysis. Furthermore, the particular attention was paid to technical services. The research results of a few types of aircraft in terms of the technical service malfunction and damage impact on their technical readiness level were also presented. At the end, the importance of such an approach and the possible use in practice were emphasised.

Opis:
Two ammonites Teschenites subflucticulus Reboulet and Criosarasinella mandovi Thieuloy have been found for the first time in the Flysch Carpathians. They occur in the so far poorly dated Early Cretaceous flysch deposits of the Silesian Nappe at Poznachowice Dolne, in the Upper Cieszyn Shale and the Hradiště (Grodziszcze) beds lithotypes, respectively. Teschenites subflucticulus points to Late Valanginian (Furcillata Zone), but nanno- plankton points to Late Hauterivian-Late Barremian and dinocysts to Late Hauterivian, all analyzed from the same sample. Criosarasinella mandovi points also to Late Valanginian (Furcillata Zone), what is not in contra-diction with the nannoplankton assemblage (Early Valanginian-Early Barremian) analyzed from the same bed, but dinocysts suggest Late Hauterivian. Preservation of the ammonites and sedimentary features of their host beds exclude redeposition. The difference in age by almost 3 Ma years between the ammonites and microfossils cannot be satisfactorily explained according to the current knowledge on their biostratigraphic meaning; it is left as it is as a dilemma.
