    FAILURE RATE ANALYSIS IN AIRCRAFT MAINTENANCE PROCEDURES
    (Žilinská univerzita v Žiline, 2020) Bugaj, Martin; Pecho, Pavol; Janovec, Michal
    An aircraft is a complex object composed of many complicated and interrelated parts, components and systems. Reliability of all parts and systems is very important to aircraft because operation of aircraft can affect flight safe directly. Aircraft failure rate is an important parameter of aircraft operation to maintain the effective level of reliability. The failure rate is the probability of failure at a point in time. When a part, component or system is not functional it can be upgraded through replacement or repair, and the condition of the aircraft is restored to some degree. We can defined several approaches to aircraft maintenance. There are maintenance can be based on condition, which is, items are repaired when they fail. Failure during operation can have serious consequences, so detection of items with a high probability of failure through periodic inspection is a major component of maintenance. This paper analyses how we can define the aircraft failure rate and its impact on operational reliability of aircraft.

    FMEA ANALYSIS OF AUTOMATIC RESCUE PARASCHUTE SYSTEM FOR CIVIL AVIATION
    (Žilinská univerzita v Žiline, 2020) Pecho, Pavol; Gáborová, Miroslava; Škvareková, Iveta; Ažaltovič, Viliam
    The article analyzes the topic of rescue parachute systems, with a focus on pilot parachutes used by civic aviation pilots in emergency situations. The work is in addition to pilot parachutes, focused and most ballistic rescue systems for aircraft and firing parachute systems, which fulfill an equally important role in aviation. The issue was analyzed by FMEA analysis, which was applied to the automatic rescue system. The outcome of this study is the evaluation criteria of current technical systems to reduce the risk number “R”. For each of the safety enhancement solutions, the article contains a separate proposal for technical improvements that are suitable for implementation in practice. Such solutions ultimately represent an increase in civil aviation safety as such.

    THE MEASUREMENT OF PILOT WORKLOAD
    (Žilinská univerzita v Žiline, 2020) Škvareková, Iveta; Ažaltovič, Viliam; Pecho, Pavol; Kandera, Branislav
    The article is focused on objective measurement of pilot workload during IFR flight. For the purpose of our research, we decided to use eye monitoring technology to record eye movements to determine the pilot's performance. Eye monitoring provides data on the number of eye movements,number of visual intakes, number of saccades, number of blinks, fixations and the durations of these. Our study incorporated overall six pilots divided into two groups: the experienced and inexperienced. The measurements were performed on the ELITE S923 flight simulator located at Žilina airport, Dolný Hričov. Measurement and analysis of the data showed that the pilots showed significant deviations when comparing the two pilot samples. We also demonstrated various scanning techniques during ILS and NDB approaches. The conclusion of our work summarizes the measurement results and the use of eye track technology in the future.

    PRAVDEPODOBNOSŤ NEHODY BEZPILOTNÉHO LETECKÉHO PROSTRIEDKU NA ZEMI V OBÝVANEJ OBLASTI
    (Žilinská univerzita v Žiline, 2020) Ažaltovič, Viliam; Škvareková, Iveta; Pecho, Pavol; Kandera, Branislav
    The study in this paper defines the amount of the possible ground casualty risk of randomly falling out-of-control UAV on a picked flight path, which was defined from the city of Žilina to the city of Martin, which were 29 km apart. For this area, the probability of a third party casualties caused by lose of control during the flight of UAV, was calculated. For these calculations was used the Equivalent Level of Safety approach. The conclusion provides recommendations for safety improvements during planning flight routes for unmanned aerial vehicles.
