    Proposal of the FI (S) seminar program for DTO according to the conditions of CAA-ZLP-161
    (University of Zilina, 2022) Michálek, Tomáš; Pecho, Pavol
    The aim of this paper is to create a proposal for a seminar program for sailplane instructors. Since 2021, new European legislation has come into effect regulating the flight crew licensing. Part of this legislation is the obligation to attend a seminar for each instructor once every 3 years. The seminars can be organized by the declared training organizations (DTO), for which the organization of these seminars is new and have no experience with it, so this program proposal can help them organize the seminar. This research deals with current legislation, analysis of conditions imposed by EASA, analyses the current recommended flight instruction syllabus for new flight instructors together with the syllabus for training new pilots, analyses selected aviation accidents and finally analyses important chapters in aviation medicine.

    Analysis of implementation instrument approaches for hems heliports
    (University of Zilina, 2021) Posluch, Samuel; Pecho, Pavol
    In recent years, the trend of using a helicopters in the operation of the helicopter emergency medical service (HEMS) has been increasing. The reason is the wide range of uses of the helicopter, fast and safe transport of wounded people using new copters. Nevertheless, it is not possible to operate flights in poor weather conditions with a sufficient number of interventions. There is a need to develop new procedures for flying even under conditions other than VFR flight rules. The current state of helicopter technology in Slovakia allows it and therefore it is appropriate that new procedures using GNSS be created to establish a safe flight. The aim of the analysis is to evaluate the input factors available to the operator and to create a design approach based on the legislative requirements for the use of GNSS systems on the selected heliport. The resulting approach design can be used as one of the options for creating procedures. Such proposals could also be implemented on other operational bases, for the creation of a network of instrument approach or departure systems, which would create space for increasing the safety of helicopter emergency medical service in Slovakia.

    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.
