    A comparative analysis of Instrument Landing System and Ground-Based Augmentation System Landing System for aircraft landing guidance
    Azjargal, Gombo-Ochir; Géza, Husi; DE--Műszaki Kar
    Achieving a successful aircraft landing demands reliable and safe approach guidance, particularly under low visibility conditions. Although various aircraft landing guidance systems coexist in aviation, this thesis concentrates on a comparative analysis of the Instrument Landing System (ILS) and the Ground-Based Augmentation System Landing System (GLS) from multiple perspectives. The fundamental principles of each system are explained in detail to provide distinction between their operational and technical characteristics as well as their working mechanisms. Core differences and similarities between ILS and GLS are subsequently compared in terms of accuracy, reliability, safety, and economic considerations. Furthermore, a case study is presented to illustrate the current application of both systems, followed by future trends in landing guidance technologies. Through this comparative analysis, the thesis provides a comprehensive understanding of ILS and GLS, including their distinctions and potential contributions to aviation.

    Beyond the skies: The historic evolution of jet engines
    Nassar, Seif; Géza, Husi; DE--Műszaki Kar
    In my thesis, the beginning of the jet engine and the pioneer inventors are discussed. the contrebution of Hans Von Ohain and Sir Frank Whittle, and their efforts were illustrated briefly with their impact on the industry. The pre-jet era was described when reciprocating engines were prevalent on aircraft designs. Early jet designs such as Turbojets and pulse jets were explained, and the impact on fuel economy presented by further developments giving birth to Turbofan engines was emphasized. Supersonic propulsion jets were explained, such as Ramjets and Scramjets, and a comparison between them was made. A scientific thrust calculation of an Ideal Ramjet engine is presented with a calculation sample. Airlines future expectations from engine manufacturers was discussed with three examples of the most advanced engines in the making or already in service.

    Flightpath to a greener future: the use of sustainable aviation fuels in commercial aviation over the next decades
    Benitez Luna, Gustavo Adolfo; Géza, Husi; DE--Műszaki Kar
    The commercial aviation industry must significantly reduce its environmental impact caused by emissions. The International Civil Aviation Organization (ICAO) has implemented the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), consisting of two separate phases and setting voluntary standards for carbon reduction in the aviation sector. To comply with the requirements established by the ICAO, it will be imperative to surpass a 30% threshold for the use of Sustainable Aviation Fuels (SAF) in relation to the total consumption of jet fuel by the year 2040.

    From the First to the Future The Technical Development and Future Directions of Global Navigation Satellite Systems Its impact on Civil Aviation Navigation
    Filipovic, Aleksandar; Géza, Husi; DE--Műszaki Kar
    The invention of Global Navigation Satellite System, GNSS, have entirely transformed the world. These systems include GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo and Beidou, have become key element in many of widely spread industries, including civil aviation navigation. During the past 4 decades, GNSS has undergone significant technical development, starting from its initial introduction in the 1970s to the current significantly upgraded systems that are being used today. With exponentially improving GNS systems, it has become increasingly important to understand its process of development and its impact on civil aviation navigation. The objective of this thesis work is to provide an overview of general operating principle of GNSS; the first GNSS rated for use during IMC for air operations ; overview and comparison of current GNSS systems and finally future state-of-art GNSS. Additionally, this thesis aims to explore the impact of GNSS on civil aviation navigation, including its challenges, benefits and potential disadvantages and risks.
