  The sustainability and its key element, the environmental awareness has been known for decades, however in general can be said that in the decision making the short term economic profit is still more dominant both on the individual and company levels. In last few years the rapid growth of CO2 emission is now not just risking the human life but the flora and fauna is in heavy danger. The concerns pay more attention on their short-term profits instead of the environmental protection. First of all with the change of the leadership attitude can reach the environmentally conscious organization that can support the reduction of the emissions, so the improvement of the atmospherical CO2 concentration. In my study I’m going to present what possibilities do the companies have to reduce their emissions and how these improvements could be harmonized with the profit interests (with the reduce of electricity-, water-, and gas consumption).

  Human error will pose a threat to the operati on of Unmanned Aerial Vehicles (UAVs), just as it does in other fi elds of aviati on. If UAVs are to be permitt ed to operate in the Nati onal Airspace System (NAS), it will be necessary to understand the human factors associated with these vehicles. The aim of this arti cle is to give recommendati ons for the safe and effi cient airport operati ons management methods, processes, and examines of the Unmanned Aerial Vehicles gained over the past use of air and ground experience.

  The undiminished development of air traffic has a direct effect on the environment of airports. Year in year out the continuously growing passenger traffic has increased the number air flights. The technological development has made it possible to increase the size and performance, - and with it the transportation of heavier payload - of aircraft. Of course, it has necessarily resulted in more fuel use (burnt fuel) emitting more pollutants into the atmosphere. In addition this effect appears not only during the high altitude flying polluting the high atmosphere, but due to the today very busy and the continuously increasing ground aircraft motion (taxiing) contaminating the close surroundings of the airport. With some innovation and technological development we can make the airports not only more environmentally friendly but also cost effective. In this paper I would like to introduce the possible use of renewable energy sources and the ground movement of aircraft without their own engines.

  A new aircraft has appeared at the flying troops of the Hungarian Defence Forces which also brought about the emergence of a new maintenance strategy. The new strategy meant a switch of the operating technology at the same time, and it also posed a set of management problems, especially in certain stages of the conversion process. The morphostatic or morphogenetic nature of the change has been brought up as a fundamental question; the successful realization of this change requires various management procedures. In the present study I make an attempt to compare the two operation strategies that are simultaneously present, from which it may emerge that what processes are affected by the changes and at what level they are affected. In my view the usefulness of the analysis lies in the fact that the efficiency of integrating a new aircraft into the system may considerably increase in the future.

  Aviai on is the quickest and most praci cal way of locomoi on, to which people have been paying at eni on for thousands of years. Today – on account of air traffi c, energy crisis and environmentalism – the power source of the aircrat became a key issue. In addii on to fl ight safety, there is a growing emphasis on environmentally friendly operai on. The ineffi cient burning of fossil fuels comes hand in hand with the signifi cant pollutant emission and noise pollui on which bother even those living far from the airports. Nowadays the most important objeci ve of researchers and developers is to create an effi cient, clean and quiet airplane, thus as a new idea they at empt to ui lize electricity in this form on board the aircrat . The ari cle presents some various energy resources through some example of unmanned aerial vehicle.
