Contrails created by aircraft are a very hot topic today because they contribute to the warming of the atmosphere. Air traffic density is very high, and current forecasts predict a further significant increase. Increased air traffic volume is associated with an increased occurrence of contrails and induced cirrus clouds. The scientific level of contrails and their impact on the Earth’s climate is surprisingly low. The scientific studies published so far are mainly based on global models, in situ measurements, and satellite observations of contrails. The research is based on observations of contrails in flight paths in the vicinity of Děčín and Prague, and the collection of flight and meteorological data. It focused on the influence of the meteorological situation on the formation of persistent contrails. The collected data on contrails and meteorological variables were statistically processed using machine learning methods for classification models. Several models were developed to predict and simulate the properties of contrails as a function of given air traffic and meteorological conditions. The Random Forests model produced the best results. Dependencies between meteorological conditions, formation, and contrail lifetime were found. The aim of the study was to identify the possibility of using available meteorological data to predict persistent contrails.

There is currently a lot of pressure on airlines to reduce emissions, noise and fuel consumption. Another aspect is the drive to reduce operating costs, which leads to investment into the new technologies and also to the introduction of new procedures. One of these procedures is the so-called 'Single-engine Taxi-out', which aims to save fuel during taxiing. Together with this, the costs for the entire flight are reduced. Research at the department of Air Transport at the Faculty of Transportation Sciences of the Czech Technical University in Prague is underway to reduce the financial costs and emissions produced during each flight. One successful solution is to reduce emissions and the associated cost by using single-engine taxi procedures.

The airport and in its surroundings is a necessary condition for maintaining high air traffic safety. For this purpose, airports establish their own Fire Brigades. The article analyses in detail the regulations and documents related to the mandatory provision of rescue equipment at airports in case of an air accident or incident. These are exclusively ICAO Annex 14 and the adopted document L14. Based on the analysis, shortcomings were identified in terms of the required equipment, where the regulations only provide for fire and aircraft extrication. This result was found to be insufficient as there are other threats in air traffic which are not mentioned in the current legislation and the Fire Brigades must rely on their previous experience or the experience of other brigades in the world. The model airport V. H. Prague, where we performed a comprehensive verification of rescue equipment in relation to the regulatory base, demonstrated a significantly higher level of equipment than prescribed by the current legislation. This has led to the development of several general recommendations for the provision of rescue equipment to cover hitherto neglected risks. As part of the recommendation process, sub-parameters of airports were considered to increase efficiency. If some of these recommendations can be implemented in future legislation, the ways in which the Fire and Rescue Service can deal with emergencies will be developed and thus the safety of the whole system will be improved.

Contrails are line-shaped clouds formed behind aircraft which may persist for hours while growing to resemble cirrus clouds. Contrails cause positive radiative forcing which tends to warm the atmosphere. This paper describes the contrail formation, climate effect and contrail research carried out by the Department of Air Transport, Faculty of Transportation Sciences, Czech Technical University in Prague. The research is based on contrail observation, ADS-B messages, Mode S messages and aerological measurement. The aim of the research is to identify the frequency of contrail occurrence, their lifetime and other properties and compare them to meteorological conditions.

Air transportation has undergone a significant and noteworthy development over time. No other mode of transport has achieved such development as aviation and it is rightly considered the safest mode of transport. More powerful and safer systems are being developed, with an increasing level of automation eliminating the risk of human error. Weather has always had a significant impact on flight. Thanks to the modern technology, commercial aviation becomes less and less dependent on weather; however, it is still one of the main factors affecting air transport safety. Hence, pilots should have good meteorological knowledge. The training syllabus of pilots includes piloting under unfavorable and difficult meteorological conditions to help enhance the safe flight performance.

The subject of this paper, which is based on a bachelor thesis, is the weather forecast at Václav Havel Airport, Prague. The paper describes how modern weather forecasts work. For almost half a year, there were recorded specific daytime predictions of individual meteorological elements. All forecasts have been taken from publicly available resources. The practical part focuses on the creation of reliable statistics from data that are based on real predictions of individual models and the following evaluation of their accuracy, stability and interdependence. Based on statistical calculations, the each method was evaluated by comparing with the other. Based on the results, it is possible to recommend specific numerical models for civil and aviation users.

To allow better acces for VFR pilots to hold IFR privileges, EASA introduced new pilot Qualification – Basic IR. This new qualification is porposed by EASA document NPA 2016-14, which introduces priviliges and repsonsibilities for this qualification. Basic IR is based mainly on existing license En-route IR but with signifcatn differences. Main difference is possibility to use basic IR even for 2D and 3D approaches. Even thought Basic IR is based on competency principles, it shall not be confused with competency based IR qualification, which holds differeNt privileges. With introduciton of Basic IR are connected several issues and problems which covered in this article. Every information in this article is referenced on NPA 2016-14

Air transportation has a non-negligible effect on the Earth’s atmosphere. Contrails are one of the factors causing changes in the atmosphere. Their global influence on the climate is not yet well understood, but there is a presumption that the dominating effect should be the greenhouse or the warming effect. Their formation depends on suitable atmospheric conditions and phenomena that create these conditions. Because their influence on the radiation balance is presumed to be positive, it is important to focus on the reduction of the formation of persistent contrails and to mitigate their effects. Methods and technologies that are needed to accomplish desired objective, however, require an increase in the economic, operational and technological capacities in the air transportation. We described global and operational changes to the operating methods such as shifting of cruise altitudes and spatial and temporal regulation of flights. From the technological viewpoint, we mentioned engine efficiency, alternative fuels and physical changes to airframes and their effect on the contrails formation. In this research, we identified the elements that contribute to the increase of the radiation forcing and the formation of contrails and contrail-cirrus and the relations between them. The conclusion outlines gaps, filling of which would improve the understanding of the formation of contrails.

This paper deals with the incorporation of the Centralized Approved Training Organization into the structure of flight training facilities in the Czech Republic. The work summarizes all requirements for the training organizations after a release of new regulations. The most significant changes in the requirements relate to a glider pilot training and therefore this work is focused on this particular topic. In the first part of the work we wanted to recap all the requirements and compare them with the original legislation to emphasize the changes. Then, it is discussed about a newly established flight training organization which is an Approved Training Organization or an ATO. In the third chapter, we deal with the specific requirements which must an operator complies when applying for the issuance of the ATO certificate. At the conclusion of the work we deal with the realization of the establishment of a centralized ATO for the glider pilot training. This proposal gives an example how the centralized ATO could solve the problem with a cooperation with other aero clubs as supplier organizations.
