International conventions and agreements in the field of international civil aviation
Procházková, Hana ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
This bachelor thesis deals with the issue of international conventions and agreements in the field of international civil aviation, by which the Czech Republic is bound. I drew information of this topic mainly from electronic versions of conventions and agreements and from portals dealing with either aviation or legal issues. Then I characterized each convention separately. Conventions and agreements are arranged chronologically as they have gradually evolved. For better orientation I also divided them into four main groups. I have set out a list of bilateral agreements in the annex. I also included amendments of international conventions in the annex and sample examples of questions, that can help students. For a clearer overview I created a timeline, where I again stated very briefly what the convention is about, when it was created, until when it was force, or what other convention replaced it. The work can also be used, for example, in the theoretical teaching of pilot students, or as an aid in preparing for theoretical pilot tests.

Assistant systems in car and aircraft control
Novotný, Timotej ; Horpatzká, Michaela (referee) ; Zikmund, Pavel (advisor)
The bachelor thesis deals with assistance systems in cars and aircraft. The aviation sector is focused on GA aircraft. This thesis describes assistance systems used in cars and aircraft, their contribution to traffic safety and limitations of these systems. The comparison of assisting systems in the automotive and aviation industries shows the difference in the speed of development in individual areas, which is caused mainly due to strict requirements for safety and reliability of aviation systems. Furthermore, we can see the difference in implementation of systems monitoring the condition of a driver/pilot. Although the work of a pilot is more demanding than the work of a driver, today’s aircraft do not have a system for monitoring the condition of a pilot or an emergency landing system. Part of the thesis concerning future assistance systems in aviation is devoted to the system monitoring the pilot’s condition and the automatic landing system. Both systems are still under development. However, experiments have shown that these systems could be implemented in future aircraft and increase aviation safety. The last part of the thesis mentions the future of assistance systems, which create a path to autonomous vehicles.

Aircraft windshield blowing: solution and design possibilities
Šamša, Petr ; Fišer, Jan (referee) ; Jícha, Miroslav (advisor)
My thesis is considering with aircraft windshield blowing for airplanes designed according to CS-23 regulation. The first part introduces the size of precipitation clearing area in connection with CS-23 regulation and report SAE AIR805C. Next chapter describes a few possible design solutions which can be potentially used for windshield precipitation. There are also other methods analysed in that part. There are not only the casual systems like windshield wipers but some more rare or new technologies too. It can be some fluid repellent surfaces or blowers in that category. The third part deals with jet blast system in detail. There will be a design calculation for airflow conditions which are important for the correct function. The last quarter of this thesis mentions the experiment what should compare the theoretical computations from the third part with the real values.

Modern Flight Control System Design and Evaluation
Vlk, Jan ; Holzapfel, Florian (referee) ; Rzucidlo, Pawel (referee) ; Mathan, Santosh (referee) ; Chudý, Peter (advisor)
Tato práce je zaměřena na výzkum moderních metod automatického řízení letu a jejich ověření s ohledem na současný stav poznání a budoucí využití bezpilotních letadlových systémů. Práce představuje proces návrhu automatického systému řízení letu s důrazem na přístupy z oblasti návrhu založeného na modelování (Model-Based Design). Nedílnou součástí tohoto procesu je tvorba matematického modelu letounu, který byl využit k syntéze zákonů řízení a k vytvoření simulačního rámce pro evaluaci stability a kvality regulace automatického systému řízení letu. Jádro této práce se věnuje syntéze zákonů řízení založených na unikátní kombinaci teorie optimálního a adaptivního řízení. Zkoumané zákony řízení byly integrovány do digitálního systému řízení letu, jenž umožňuje vysoce přesné automatické létání. Závěrečná část práce se zabývá ověřením a analýzou navrženého systému řízení letu a je rozdělena do 3 fází. První fáze ověření obsahuje evaluaci robustnosti a analyzuje stabilitu a robustnost navrženého systému řízení letu ve frekvenční oblasti. Druhá fáze, evaluace kvality regulace, probíhala v rámci počítačových simulací s využitím vytvořených matematických modelů v časové oblasti. V poslední fázi ověření došlo k integraci navrženého systému řízení letu do experimentálního letounu, sloužícího jako testovací platforma pro budoucí bezpilotní letadlové systémy a jeho evaluaci v rámci série letových experimentů.

Stability and control of dynamical systems used in modeling an airplane motion
Novák, Jiří ; Šremr, Jiří (referee) ; Nechvátal, Luděk (advisor)
A modern aircraft (or another machine moving in the air) usually does not rely on its structural stability only. In fact, the motion is conventionally stabilized using a loop feedback control. A dynamical system, which models the aircraft's position and orientation in time, reacts on the state variables, hence, the control signal is dynamically changed. This bachelor's thesis deals with deriving the equations of motion for small perturbations of the state variables as well as with stability and control of such a system of equations. In addition, comparison of both a nonlinear and a linearized model is a part of this work. The programming language Python is used for testing on several examples of a concrete aircraft.
