This paper has been issued in the framework of the SHERPA project under the Grant Agreement No 287246 with the GSA (European GNSS Agency). This document contains the main technical activities conducted by PANSA in the frame of project’s WP2000. The objectives of WP2000 are: To work towards the implementation of a LPV procedure at each of the scenarios; To develop EGNOS National Implementation Plans, To develop and EGNOS Regional Implementation Plan, To summarise EGNOS expected benefits in a single airport. Specifically, the objectives of this document are technical activities conducted towards the implementation of a LPV procedure in scenario: procedure design, safety assessment, business case, EGNOS service provision requirements. The first step shall be to describe the operational environment at the scenario including the level of ATS provided, CNS equipment, the airport ground equipment, airspace and any procedures in place. The purpose of the operational description is to define the CONOPS specific to the airport. The Final FHA of LPV approaches is based on the Operational Model of LPV approaches in the ECAC Area, which clearly defined nominal operations prior to analyse degraded cases. For each operational action (performed by either system, human operator or jointly in the successive phases of flight), relevant failure modes were identified. Each failure mode was then analysed in turn in terms of examples of causes (to check its validity), operational consequences and mitigations, hazards, rough risk comparison against ILS operations, and when pertinent, recommendations in terms of risk reducing measures to be considered. Safety Case Activities drawn up as part of the SHERPA project was accepted by GSA, EUROCONTROL. At present an algorithm of acting while designing and executing procedures constitutes final approaches according to GNSS.

W artykule przedstawiono proces transformacji w światowej nawigacji powietrznej, który implikuje konieczne zmiany w działalności lotniczej. Wynikają one z konieczności implementacji podpisanej rezolucji A-37 ICAO, nakazującej wprowadzenie w każdym kraju nawigacji opartej na PBN (Performance Based Navigation - PBN). Oznacza to przechodzenie od nawigacji sensorowej do dokładnościowej, stanowiącej istotny element utrzymywania witalności lotnictwa, a jednocześnie zapewnia: bezpieczne, wydajne i elastyczne użytkowanie przestrzeni powietrznej, ochronę środowiska naturalnego, zrównoważone operacje na globalnym, regionalnym i krajowym poziomie. Finansowanie ewolucji nawigacji odbywa się poprzez realizację międzynarodowych programów naukowo- badawczych np. SESAR. Polska uczestniczyła w projekcie SHERPA, w ramach którego opracowała i wprowadziła do operacyjnego działania 21 procedur podejścia do lądowania RNAV GNSS. Przeprowadzone w ramach tego projektu eksperymenty umożliwiły opracowanie tego tematu.

The article shows the process of transformation in the world’s air navigation which implies necessary changes in air activity. These changes resulted from the necessity to implement the resolution A-37 ICAO, which ordered implementation the Performance-Based Navigation (PBN) in every country. This basically means to move sequentially over time from sensor’s navigation to navigation based on accuracy, which is a major milestone for aviation as well as ensures: safe, efficient and elastic using the airspace, protection of the natural environment, balanced operations on global, regional and domestic levels. Funding of these transformation is provided through the realization of international research and development programmes and activities – for example SESAR. Poland also participated in the SHERPA project, in frames which 21 procedures of the RNAV GNSS final approach were established and introduced into the operational use. Experiments conducted as part of this project enabled development of this topic.

The article shows process of the implementation satellite systems in Polish aviation which contributed to accomplishment Performance-Based Navigation (PBN) concept. Since 1991 authors have introduced Satellite Navigation Equipment in Polish Air Forces. The studies and researches provide to the Polish Air Force alternative approaches, modernize their navigation and landing systems and achieve compatibility with systems of the North Atlantic Treaty Organization (NATO) and International Civil Aviation Organization (ICAO). Acquired experience, conducted military tests and obtained results enabled to take up work scientifically - research in the environment of the civil aviation. Therefore in 2008 there has been launched cooperation with Polish Air Navigation Services Agency (PANSA). Thanks to cooperation, there have been compiled and fulfilled three fundamental international projects: EGNOS APV MIELEC (EGNOS Introduction in European Eastern Region - APV Mielec), HEDGE (Helicopters Deploy GNSS in Europe), SHERPA (Support ad-Hoc to Eastern Region Pre-operational in GNSS). The successful completion of these projects enabled implementation 21 procedures of the RNAV GNSS final approach at Polish airports, contributing to the implementation of PBN in Poland as well as ICAO resolution A37-11. Results of conducted research which served for the implementation of satellite techniques in the air transport constitute the meaning of this material.

During performing researches as part of the European programs associated with the implementation of new techniques and the technology in aviation, it turned out that it is necessary to prepare a “Business Case” document. During the completion of three international projects, as part of workshops, there were accepted certain theoretical models of drawing these documents up. There was a need to prepare the appropriate model solution for every country. The article is presenting such model as well as method of business analysis which should be applied in the air transport during the implementation of new techniques and the technology. The algorithm of execution of the “BUSINESS CASE” was presented in the following sections of the material – its validation took place during the international project SHERPA (Support ad-Hoc Eastern Region Pre-operational Actions in the GNSS).

Podczas wykonywania badań w ramach europejskich programów związanych z implementacją nowych technik i technologii w lotnictwie, okazało się niezbędne przygotowanie analizy biznesowej w formie dokumentu „Business Case”. W wyniku zrealizowania trzech międzynarodowych projektów oraz walidacji przyjętych założeń podczas zajęć warsztatowych, został zaakceptowany i przyjęty na forum europejskim teoretyczny model sporządzania tego dokumentu. Na tej podstawie konieczne było przygotowanie odpowiedniego rozwiązania modelowego w każdym państwie. W artykule przedstawiono zarys teoretyczny przyjętego modelu jako metody analizy handlowej, która powinna być zastosowana w transporcie lotniczym, podczas wprowadzania nowych technik i technologii. Algorytm wykonania dokumentu „Business Case” został przedstawiony w kolejnych częściach materiału a jego walidacja nastąpiła podczas międzynarodowego projektu SHERPA (Support ad-Hoc Eastern Region Pre-operational Actions w GNSS), w ramach którego implementowano 21 procedur podejścia RNAV GNSS na polskich lotniskach.

Accidents caused by human error are prominent in the medical field. The present study identified medical errors in the emergency triage area by assessing the tasks of all healthcare workers employed in the triage area of an educational hospital in Tehran, Iran in 2014. Data were collected using the systematic human error reduction and prediction approach (SHERPA). The tasks and sub-tasks were determined and analyzed using hierarchical analysis and the errors were extracted. A total of 199 human errors were identified in the different tasks. The rate of error for action was 46.8%, checking was 25.6%, retrieval was 8.5%, communication was 12.1% and selection was 7%. Rate of unacceptable and unfavorable risks were 21.1% and 38.6%, respectively. SHERPA was shown to be an appropriate technique for detecting medical errors. The establishment of control programs should be a high priority in the management and implementation of health facilities in triage areas.
