This article focuses on the types of meteorological conditions with which the aircraft comes into contact during the flight, with a closer focus on the take-off and landing phases of the aircraft. The topic of meteorological conditions and their effects was chosen due to the enormous importance of this segment of aviation for the safety and operation of air traffic. The paper has a theoretical character and approaches the connection between individual meteorological conditions and their effect on the behavior of the aircraft. For air safety, a proper interpretation and subsequent adaptation to the corresponding weather events and deviations from standard conditions is essential. The aim of the publication is to define the basic meteorological conditions, weather phenomena and to underline their considerable importance for air traffic. The final part is devoted to the analysis of air accidents during takeoff and landing, which were caused by adverse weather conditions and their underestimation.","PeriodicalId":297194,"journal":{"name":"Práce a štúdie","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130637249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We achieve low weight by using lightweight aluminum air-cooled cylinders. In my work, I deal with the fundamentals of two- and four-stroke internal combustion engines. The importance of primary and secondary forces caused by the movement of the crankshaft and pistons is also discussed. Of course, we'll go over how to fill the engine while it's running (carburetor/injection).

Subsequently, I deal with the data that are displayed by the devices, but also their design and the comparison of the current state compared to the initial versions. Innovations of aircraft instruments are focused on both components and the display of flight data, which leads to simplification of their operation and individual assembly. One of the advantages of modern instruments is their ability to detect errors that may occur during the flight, which serves the pilots to ensure the flight. Furthermore, I focused on the system of collection, processing and evaluation of information, as well as their final production on board the aircraft. My work is mainly focused on the Dynon system, whose functions, display and implementation I described in detail, use and design in aircraft cockpits.

Already existing modifications are described, as well as new ones with the aim to strengthen its critical parts. Structural modification of the wing hinge and beam, replacement of rivet joints with stronger Hi-Loks and use of different hole angles to ensure a firmer joint and better stress distribution around these holes are covered.
