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:
In this paper there have been presented results of an analysis of repair efficiency for an emergency repair subsystem (technical service units) in a selected transportation system. The research object was a real system of municipal transportation, in a given urban agglomeration. Experimental data, necessary to determine values of indexes describing efficiency of repairs performed by the technical service units, come from a selected group of technical objects (city buses) used in the analyzed system. The data was obtained on the basis of experimental tests conducted within the studied system, employing a method of passive experiment, in conditions natural for the technical objects functioning. This work presents a method according to which the values have been determined and the analysis of efficiency of repairs performed within the emergency subsystem has been made. The values of repair efficiency assessment concern selected systems of the analyzed buses. The selection of these systems was made taking into consideration the number of the studied systems failures. The obtained results have been demonstrated in the form of tables and graphically, in charts. On this basis, there has been made an analysis of efficiency of repairs performed by emergency repair units. Due to its general character, the presented method can be used for an assessment of repair efficiency both within operation and maintenance systems of technical objects of different types and efficiency of repairs performed at particular repair stations, groups of stations or subsystems providing vehicles with serviceability.

Opis:
This paper attempts to clarify what impact has selected technical maintenance tasks on the effectiveness of the braking system with special emphasis on the initial break-in period of associated components. Were conducted studies involving measurements of braking forces on a rolling station and road tests Renault Thalia of car braking during which was recorded deceleration, speed, temperature of brake discs and the force of the pressure on the brake pedal. Braking process on the rolling station was assessed with a braking efficiency ratio as a criterion. However, results collected during road tests allowed studying for more accurate of running-in process of car barking system elements. This was due to taking into account the total vehicle braking force compared with the force applied to the brake pedal. The study was performed for the discs and brake pads exhibiting a different degree of wear, with particular emphasis on the running-in elements occurring immediately after replacing brake pads. In this case, there is a noticeable loss of performance brake system, which persists after initial running in mating faces of the pad and the brake disc. This phenomenon is known from workshop car service practice, but there is a need for sensitization of staff at the Pre-reaching elements of the service operations, because operation of a vehicle with a temporarily reduced efficiency of the braking system on a public road has the potential to cause threats to the safety of road users.
