For decades, records have been kept in the field of air traffic services on every issued ATC clearance based on the service performance directive. There are various information carriers used for this recording. Technological progress has shifted this operation from paper to digital records. This article compares two of the most commonly used methods of recording issued permissions: the traditional method of paper flight strips and the modern stripless system. This research aims to conduct a comprehensive analysis and assess the impact on flight management efficiency emphasizing air traffic controller situational awareness. In the case of the conventional method, it is necessary to monitor more values outside the scope of the situational display, physically move the flight strip holders, located outside the field of view, and tilt the head down. In the second case, the system offers the necessary functions for data entry as an integrated part of the software. Therefore, diverting the view outside the display unit is not necessary. Using both recording methods, an experiment was set up to measure the air traffic controller's situational awareness level. The Situation Awareness Global Assessment Technique (SAGAT) system was used for situational awareness assessment. The research and real life experience indicate, that the stripless recording method has smaller negative impact on situational awareness and is more user friendly. Subjects maintained a better situational overview compared to the paper-based method. This article presents the strengths and weaknesses of individual methods and contributes to the discussion of cognitive functions in air traffic control.

With the ever-increasing demand for air travel, airspace capacity in the vicinity and relative proximity of airports is reaching its limit. With the progressive development of new technologies and their advancement, industry has reached a situation where it is physically possible to have a large number of aircraft in the airspace. Unfortunately, under current operational conditions, reaching these theoretical capacity values is impossible as it is outside human capability to handle such extreme numbers of aircraft safely and efficiently. This limitation is mainly obvious at peak times when runway and sector capacity is at its limit. This article focuses on the capacity of Václav Havel Airport in Prague (LKPR) and the airspace in its vicinity. It presents a proposal to apply a reduced horizontal separation minimum on the final approach phase of instrument flight rules (IFR) flights down to 2.5 NM. Also, it evaluates the impact of this reduction and describes the necessary changes in airport infrastructure, legislation, and air traffic control unit procedures. The implementation proposal is based on the practices at airports abroad with a reduced 2.5NM spacing already applied. The experiments carried out showed that the idea of reduced spacing at LKPR is feasible and brings an increase airspace capacity while maintaining an adequate level of safety. Under ideal conditions and traffic composition, an increase in the number of aircraft handled by more than 10% per hour can be reached.

The present paper deals with the specifics of terminology of both powered and glider aerobatics. In addition to English terminology and Slovak and Czech equivalents, the paper presents also selected aspects of professional jargon and typical phraseology applied in international aerobatic contests from the perspective of judges. Although the Slovak-English terminology equivalents in terms of flight aerodynamics and mechanics are tackled in the work Slovenský letecký slovník, terminologický a výkladový by Nedelka a kol. (1998), it is possible to identify certain elements of the terminology, which are not discussed in the mentioned work. The aim of the paper is to expand on the terminology listed in the aforementioned dictionary and define terms commonly used in aerobatic practice. Moreover, the additional expressions are briefly analysed and compared in terms of word formation.
