The purpose of the paper is to examine product innovation which enables achieving higher fuel efficiency by its lower usage per unit, introduced by two leading competitors on the market of narrow- and wide-body aircraft, which are Airbus and Boeing. Technological, economical and environmental impact of product innovations are discussed. The method includes a mathematical formula to calculate fuel usage per Available Seat Kilometre (ASK). The average fuel consumption for chosen models of Airbus and Boeing as closest competitors is presented. The result of the study is to indicate the most competitive aircraft of Airbus and Boeing accordingly, which are more fuel efficient in average estimates and contribute to lower emissions, as externalities to natural environment. Indicated aircraft types can be recommended for airlines in context of economical efficiency in viewpoint of lower exploitation cost and effective fleet management.

The paper presents an exemplification of data mining techniques in aviation industry on the basis of Turkish Airlines. The purpose of the paper is to present application of data mining on the selected operational data, concerning international flight passenger baggage data, in year 2015. The differences in passenger and flight profiles have been examined. Firstly, two-steps approach allowed defining the number of clusters. Secondly, K-means clustering were applied to divide data into a certain number of clusters representing the different areas of consumption. Results can contribute to higher efficiency in decision making regarding destination offer and fleet management.

The paper presents a certain approach to diameter measurements of railway axle set wheel. The main goal of the presented research was to verify possibility of applying vision system for such measurements. The tests have been conducted with a model of axle set wheel. Several problems related to vision system application have been discussed. Among others, different image calibration techniques were analysed. Also, a possibility of single image calibration for measurements of wheels with different diameter was considered. It has been revealed that the wheels can be measured with satisfying accuracy based on few images of a wheel rotating in front of the camera. However, distinct problems have been pointed at while analysing practical implementation of the proposed approach in the industrial conditions. These problems reflect our future work.
