This paper focuses on the specificities and semantic meaning of Mikhail Bulgakov's metadrama White Guard and The Flight. The standard conception of metadrama is to purposefully break the dramatic illusion and make bare a playwright's self-consciousness of the theatrical art itself. With the use of the metadrama Bulgakov expressed the essentials of ugly reality, which he couldn't accept as a valuable truth. In this respect, Bulgakov's metadrama becomes at once a window, from which he views the external world in the theatrical vision, and a mirror, in which his political and existential stance as a playwright is reflected. In White Guard Bulgakov described the already theatricalized reality through several instances of 'play-within-play'. In The Flight, composed of eight pieces of dream, a life turned out to be a less solid and less firm reality than dream. Continuously demolishing the cognitive wall between reality and illusion, Bulgakov leads spectators to have a reflective view on the reality. Allowing more powerful demonstrativeness for a play-within-play than for a play-within-play, Bulgakov elevates a metadramatic technique to the level of thematic structure.

Statistical data have shown that most of aircraft accidents attributed to the spatial disorientation result from visually restricted environments such as a flight amid clouds or a night flight, in particular during roll maneuvering. This study investigates the time necessary for a flighting pilot to recognize a sloped status as a horizontal status on the condition that the roll maneuver is operating when the visual sense is blocked In this study, aspects which affect such disorientation phenomena are examined. The result of this study shows that a pilot is rushed into a somatogyral illusion when a certain time elapses with visual sense blocked, and that as a speed of the flight increases and a bank of aircraft decreases, so a rushing time increases rapidly.

Helicopter accidents due to spatial disorientation in low visibility conditions continue to persist as a major issue. These incidents often stem from human error, typically induced by stress, and frequently result in fatal outcomes. This study employs machine learning to analyze flight data and evaluate the efficacy of a flight illusion detection algorithm, laying groundwork for further research. This study collected flight data from approximately 20 pilots using a simulated flight training device to construct a range of flight scenarios. These scenarios included three stages of flight: ascending, level, and descent, and were further categorized into good visibility conditions and 0-mile visibility conditions. The aim was to investigate the occurrence of flight illusions under these conditions. From the extracted data, we obtained a total of 54,000 time-series data points, sampled five times per second. These were then analyzed using a machine learning approach.

According to the results of a survey by Boeing, LOC-I (Loss of Control in Flight) was the highest in the number of deaths by fatality accident category in the past 10 years from 2012 to 2021, and the number of deaths worldwide due to LOC-I accidents was 757. It turned out to be the biggest cause of aircraft fatalities, with a figure close to twice the sum of UNK (Unknown or Undetermined), which is the 2nd place, and CFIT (Controlled Flight Into or Toward Terrain), which is the 3rd place. This study set six scenarios related to spatial disorientation that may occur during sensory-dependent flight targeting student pilots and instructor pilots at domestic designated specialized educational institutions using flight simulation training equipment, and in each scenario, the pilot's. The need for SDRT (Spatial Disorientation Recovery Training) is verified by analyzing the flight experience and recovery ability by qualification, and SDRT is repeatedly performed to verify and present the training cycle and time.

비행착각(Vertigo)이란 공간상에서 헬리콥터의 위치, 자세, 움직임 등과 관련된 인지가 부족한 상태를 일컫는다. 짙은 안개 속이나 야간비행 등, 지평선이 보이지 않는 상황에서 비행할 때 비행착각에 빠지기 쉽고 시야가 넓더라도 구름 모양이나 바람 등 기상 조건, 지상물의 상태 등 시각적인 원인, 기체의 자세나 중력가속도의 변화 등과 같은 감각적인 원인에 의해 빠지기도 한다. 조종사 비행 훈련에 있어 지각 및 감각을 요구하는 헬리콥터 비행 훈련의 특수성에 따라 조종사 훈련을 위해 기존의 상용 비행 시뮬레이터 프로그램에 6축 모션 시스템을 적용한 모의비행훈련장치 모션 시스템의 설계와 프로그램에 관하여 연구하였다. 본 연구를 통해 제작된 모션 기반 헬리콥터 시뮬레이터를 활용하여 조종사의 훈련에 활용할 경우 기존에 활용되던 시각 기반 모의비행훈련장치에서 높은 성과를 확인할 수 없었던 비행착각 예방에 긍정적인 효과가 나올 것으로 예상된다.

Not only in Korea, but also in other countries, most helicopter accidents occur at low altitude. Analysis on accidents data collected both in Korea and other countries has brought two conclusions. Firstly, helicopter operations during the night hours carries a high risk. Secondly, the most common cause of night hour operations is loss of control due to the flight illusion. As an operation relying on a night vision in particular has a very high accident hazard, accompanying instruments such as NVG are ought to be provided. Hence, a thorough preparation and inspection on missions for night forest fire extinguishing should be required and perfect guidelines/road maps and enough training programs for the operation should be provided before the engagement in missions.
