DEFINOVANIE EKONOMICKÝCH A VÝKONNOSTNÝCH PARAMETROV PRE TRETIE REFERENČNÉ OBDOBIE (RP3)

MIROSLAV BARTOŠ, BENEDIKT BADÁNIK

Abstract:
One of the most important goals of the Single European Sky initiative is improvement of ATM system and its performance. European Commission uses Performance and Charging schemes (regulatory instruments) to drive ATM performance in cooperation with the Member States, their National Supervisory Authorities and operational stakeholders. The article deals with the current review process of the European Commission in preparation of Reference Period 3 (RP3) and it defines economic and performance parameters of the Europen ATM system for RP3.

SLEDOVANIE KAPACITY PERSONÁLU PLÁNOVANIA PREVÁDZKY NEPRAVIDELNEJ OBCHODNEJ LETECKEJ DOPRAVY

JÚLIA HANKOVSKÁ

Abstract:
This paper deals with the time capacity of the Operation Control Center (OCC) personnel. Firstly, the main features of Business Aviation and OCC Personnel work responsibilities and limitations are described. Based on these facts, the necessity of their time monitoring is proven. Secondly, the method based on key indicator performance is pictured. The formula to calculate monitored coefficient is written up and procedure of data collecting from real operation is composed. The data are uploaded to business intelligence tool and visualised to interactive dashboards. The graphs show the time capacity performance and two simulations are prepared to show alarming results. Finally, the negatives and positives of such implementation to the real operation are mentioned.
Keywords:
business aviation, time capacity, OCC, dispatchers

MODERNIZÁCIA SLEDOVACÍCH SIETÍ V EURÓPE

NIKOLAS ŽÁČIK , ANDREJ NOVÁK, ŠIMON HOLODA

Abstract:
As a matter of optimization of radar networks using different alternatives, it is necessary to actively monitor current technological trends in the world. International organization EUROCONTROL organizes annual progress meetings with the aim to support key factor – implementation of new surveillance technologies. The purpose of the article is to keep awareness of current status and trends in the global picture of the optimisation. Nowadays the biggest focus gets ADS-B technology with cooperation of existing WAM systems due to significant impact on its surveillance capabilities and overall quality. Currently deadlines have been accepted as coming from directives of EUROCONTROL as well as European Union. This article is published as part of the dissertation thesis of the main author.

VYUŽITIE 3D TLAČE PRI OPTIMALIZÁCII OBEŽNÉHO KOLESA KOMPRESORA

JOZEF ČERŇAN, PAVOL PECHO, MARTIN BUGAJ

Abstract:
Rapid prototyping technology is a means to help engineers in the design and verification of some functional properties of future products before they get into production. In this paper, optimization of the radial compressor impeller was performed in an experimental form. Implementation was carried out using with 3D printing. Several variants of impellers have been installed in the model of turbine engine and subsequently tested. The purpose of the work and the measurement was to find out how the changes in the geometry of the blades are reflected to the air flow behind the compressor. The measurement results approximated how the change in the pressure in the combustion chamber were affected by using different wheels of the modified blade geometry compressor and demonstrated the possibility of improving the performance of the compressor.

SLUŽBY REGIONÁLNEJ LETECKEJ DOPRAVY: SÚČASNÝ STAV RIEŠENEJ PROBLEMATIKY V EURÓPE A VO SVETE

ALENA NOVÁK SEDLÁČKOVÁ, ANNA TOMOVÁ Jr.

Abstract:
The paper summarizes the latest scientific contributions published in the scientific database ScienceDirect in 2018 up to May, containing the terms regional airline, regional air carrier and regional air services. The review has shown that the issues of regional air carriers and regional air services are less present as a self aligning topic in current research. Our paper has also revealed that the terms regional airline and regional carrier were used very arbitrarily and many times in repugnant meaning. From the results of review, the perspective tracks of research aimed at regional air services and regional air carriers have been set, namely regarding their strategies, missions, operating models and quality of services.

VYUŽITIE ULTRAZVUKOVEJ TECHNIKY PHASED ARRAY NA KONTROLU KOMPOZITNÝCH LETECKÝCH MATERIÁLOV

MICHAL JANOVEC, MARTIN BUGAJ

Abstract:
The paper describes the use of the Phased Array ultrasonic technique for the control of aerospace composites. The paper explores the possibility of using the Phased array technique to detect the CFRP material’s defects, such as delaminations and impact damage. An error probability analysis is performed compared to the size of the defect. The use of the Phased Array ultrasonic technique when applying to FRP intelligent materials is described at the end of the paper.

LIETADLOVÝ PARK REGIONÁLNYCH LETECKÝCH DOPRAVCOV V AUSTRÁLII

ANNA TOMOVÁ, Jr., ALENA NOVÁK SEDLÁČKOVÁ

Abstract:
This paper devotes with regional air carriers in Australia focusing on their fleet through several qualitative and quantitative indicators. On the basis of performed analyses, we revealed the following types of regional air carriers in Australia: microcarriers and small carriers, medium-sized carriers an and big carriers which operate services as specialists on markets and/or they focus more on several diversified markets. This confirms the diversity of segment of regional air transportation in Australia and in general as well. Our approach can serve as a methodology to identify more subsegments hidden in regional aviation on the worldwide basis.

MERANIE ROZLOŽENIA POZORNOSTI PILOTA S VYUŽITÍM TECHNOLÓGIE EYE TRACK

FILIP ŠKULTÉTY, IVETA ŠKVAREKOVÁ, PAVOL PECHO

Abstract:
The paper focuses on measuring the pilot's attention during instrument approach. For the realization of measurement, is used the eye-tracking technology. The measurements are attended by six pilots who are divided into two groups – experienced and inexperienced pilots, and it is performed on the ELITE S923 Flight Simulator located at Žilina Airport. The aim of the paper is to find out how the scanning techniques differ between experienced and inexperienced pilots. A key factor is the experiment in which the pilot's attention is measured during a precision ILS approach and non-precision NDB approach. Measurement and subsequent data analysis demonstrated that pilots showed significant variations in scanning techniques. We also confirmed various scanning techniques during ILS and NDB approach. At the end, the results of the measurement are presented as well as further follow-up research.
