The paper analyzes the methodology of determining thesize of containers and their exchangeability in a terminal. Thesize of containers affects the exchangeability as well as the averageusability of capacity and the lack of uniformity in the deliveryof cargo suitable for container transport. These assumptionsdefine the size of the depot, the lengths and widths of theroad and railway tracks and manipulation areas, and also thenumber and size of shipping quays. Apart from these elementsthe static and dynamic capacity of the terminal depend also onthe handling equipment.

In this paper the possibility of application of the cylinderdiagnostics on vibrarion basis is given. A new method is defined.It shows advantages in comparison to the other knownmethods. The influence of various pressures in Ihe cylinder andthe influence of engine working cycle on determining of thecylinder wear are analyzed The theoretical assumptions andexperimental results have proved that this method is a newpossibility for defining the tec!VIical state of the cylinder withoutbeing disassembled, especially suitable for the practicalapplication.

The armed forces of the Republic of Croatia have beenfrom the very start of the war, imposed by the aggressor andall the time during the war, exposed to many demands and engagementof all human and material resources was required.Military air force has contributed by its sophisticatedmeans (helicopters, aeroplanes, equipment for air monitoringand guiding and air defence) to the success of all the operationsduring the war which resulted in its successful end andthe liberation of the occupied territories.The helicopters and their crews have performed numerouscombat tasks. One of them is fire support of armed helicoptersto the military units on land, against objects on land and in air.The helicopter pilots (crews) have very professionally performedthe given tasks of fire support to the military units onland.The experiences acquired during the war needed to be generalisedand the combat manoeuvres against objects on landand in air in the uncontrolled zone of the Croatian airspaceoperationalised in order to maximally utilise the possibilitiesof the aircraft and to transfer knowledge (the combat techniques)to young pilots and other crew members.This paper verifies such capabilities of the aircraft and thecrew according to war experiences and the tactics for using thearmed helicopters of the western countries (armed forces).
