조종사들은 비행시에 일상 생활 환경에서는 경험하지 못하는 여러가지 적대환경에 폭로된다. 이러한 환경에서는 인체의 평형기관은 실제와 일치하지 않는 정보를 제공해 주는 경우가 허다하다. 예를들면, 내이의 미로 전정기관이나 피하압력기관기 등은 항공기의 기동으로 발생하는 중력과 지구의 중력을 구별 하지 못하는 기능의 한계성때문에 계기비행하에서는 대개의 경우 공간정위상실, 즉 비행착각을 유발한다. 이 착각으로 인한 항공기 사고는 통계상에서 상당 부분이 치명사고로 나타나고 있는데, 이러한 사실은 비행착각현상이 비행안전에 극히 위험한 요소가 되고 있다는 것을 실증한다고 할 수 있다. 그러므로 조종사들은 비행시 공간정위 유지를 위한 철저한 대비가 있어야 한다. 공간정위 상실현상이 잘 발생하는 경우는 야간이나 기타 계기비행 환경에서 주위시각이 제약을 받을 때이다. 즉, 계기비행 환경에서의 편대비행시나 고기동시, 그리고 대조물이 모호한 야간의 활주로에서 이착륙할때 등을 들 수 있다. 비행시 공간정위 상실현상을 예방하기 위해서는 첫째로 이러한 유형의 사고분석자료를 토대로 하여 항공기의 설계단계에서부터 제작에 이르기까지 착각을 유발할 수 있는 구조적 요인을 제거해야 한다. 둘째로는 이러한 착각을 유발하지 않는 운항이나 기동방식을 택하여 비행임무를 수행토록 해야한다. 세째로 조종사들은 이러한 착각을 정상적인 인체의 반응에 의한 것이므로 자신에게도 당연히 일어난다는 사실을 용인해야 한다. 네째로 조종사들은 계기비행에 대한 구체적이고 실제적인 훈련을 통하여 계기비행 경험을 쌓아야 한다. 다음은 조종사들의 실제비행시 공간정위 상실현상에 봉착했을때의 처리요령이다. 첫째로 계기비행상황에서 자신의 감각과 계기가 일치하지 않을 때는 즉시 계기를 Cross Check하여 항공기의 자세나 기동형태를 정확하게 파악해야 한다. 둘째로 계기가 조종사의 의도대로 나타나도록 조작하고 이를 철저하게 의지하고 믿어야 한다. 세째로 자신의 감각과 계기가 일치할때까지 수평비행을 유지해야 한다. 그리고 마지막으로, 고성능 항공기가 계기비행중 저공에서 비행착각에 봉착하게 될때의 행동절차를 철저하게 숙지하고 있어야 한다.

According to the results of a survey of pilots, 92% or 230 out of 252 respondents said they had experienced flight errors during flight. As so many pilots are experiencing Spatial Disorientation, and this is one of the main causes of aircraft accidents and loss of life, so it is important to understand accurately. However, in Korea, training equipment for fixed-wing pilots has already been developed and trained, or recently developed, and some equipment for helicopter pilots is available in the Korea Air Force, but there is no environment for helicopter pilots to receive training in Spatial Disorientation prevention. Therefore, we intend to produce a helicopter-only simulator, present a program to prevent possible Spatial Disorientation during flights for helicopter pilots, and propose legal and institutional measures based on future training data.

Vertigo refers to a state in which awareness related to the location, posture, movement, etc. of a helicopter is insufficient in space. It is easy to fall into flight illusion when flying in dense fog or night flight, and even if it has a wide field of view, it can be caused by visual causes such as cloud shapes, wind conditions, conditions of ground objects, and sensory causes such as changes in air posture or gravitational acceleration. The design and program of the motion system are studied that applied a six-axis motion system to a conventional commercial flight simulator program for pilot training, depending on the specificity of helicopter flight training that requires perception and sensitivity. Using the motion-based helicopter simulator produced in this study to train pilots, it is expected to have a positive effect in prevent of vertigo, where high performance could not be confirmed in the previously used visual-based simulation training device.

UFO 목격사례가 서울 상공에서만도 90년 이후 잇달아 14건에 이르어 미확인비행체의 관심이 최근 다시 고개를 들고 있다. 미국의 콘돈위원회는 18개월의 조사 끝에 "연구가치가 없다"고 결론냈고 대부분 인간의 착각에서 오는 것이라고 설명하고 있지만 세계 도처에서 목격사례가 계속되고 있는 것이다.

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.

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.

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.

Fighter pilots are taking 'Advanced Pilot Training' courses to perform their missions perfectly even under adverse conditions. However, there are accidents that fall due to problems with the human body's equilibrium in the acceleration of flight, falling into the 'Vertigo, Spatial disorientation' phenomenon. As such, accidents that fighters fall due to spatial disorientation frequently occur not only in Korea but also abroad. In this study, we implemented the 'Vertigo' warning function in the fighter. First, we analyzed the aircraft's mission computer and the currently implemented warning functions. And we studied the coordinate system to utilize the aircraft attitude information. Based on this, we wanted to provide a visual warning to the HUD when the fighter flies over a certain time in the inverted flight position. Implementing this feature is expected to improve pilot flight safety. In addition, based on the results of this study, we propose a method to implement warning functions through linkage with other subsystems.

UPRT(Upset Prevention And Recovery Training) is an accident prevention training program developed over a three-year period after the main cause of aircraft accidents in commercial aviation between 2001 and 2011 was analyzed as LOC-I(Loss Of Control Flight). In 2014, ICAO presented UPRT for fixed-wing aircraft through Doc.10011(Manual On Aeroplane Upset Prevention And Recovery Training) and recommended mandatory implementation to Contracting States from March 2019. Since naval P-3C is a major mission of maritime patrol and anti-submarine warfare, it takes a lot of time to fly at low altitude (70-600 m), and the majority of P-3C pilots have experienced spatial disorientation, so Upset prevention and recovery training is essential for naval P-3C pilots. To this end, this study intends to present measures for UPRT from limited conditions using the P-3C simulator owned by the Navy.
