Artificial Intelligence-Based Aircraft Accident Threat Parrying Method

An anti-aircraft accident method is proposed, implemented in the decision support module, which is the main element of the flight safety control system and is a dynamic expert system. On the basis of the proposed method, recommendations are formed to the threat countering crew accidents using the information about its psychophysical state, the technical state an aircraft, external influencing factors, as well as a forecast of changes in flight conditions. The advantage of the proposed method is the ability to identify the immediate threat of an accident, as well as the development of management decisions to reduce the impact of the cause of the accident on flight safety. The peculiarity of the method of parrying the threat of an aircraft accident is the classification of management decisions depending on the flight conditions of the aircraft, which will reduce the computational costs for generating a threat parrying signal. Numerical modeling of the work using the assessment of a set of decision support rules made it possible to confirm its performance. The results can be used in systems development for safety an aircraft’s flight, the mathematical support of decision support systems.

ANALYSIS OF WING SEPARATION AND MID-AIR BREAKUP IN LIGHT TRAINING AIRCRAFT

Despite increasing discussions concerning the recently published wing spar airworthiness directive (AD) that affects many training aircraft and several current ADs for wing struts, there remains limited objective literature on incidents of wing separation or mid-air breakup. This paper attempts to report and analyse instances of wing separation and mid-air breakup of light training aircraft. A careful review of the United States National Transportation Safety Board (NTSB) aircraft accident database revealed that wing separations were more likely occur as mid-air breakup in PA28s than 172s/182s (OR: 3.06, 95 % CI: 1.3682 to 6.8536, p = .008). Additionally, wing separations were less likely to occur as mid-air breakups in the strutted 172s/182s than 177s/210s that don’t have a wing strut (OR: 0.11, 95 % CI: 0.04 to 0.29, p = <.001). This implies that non-strutted wing designs may be more susceptability to mid-air breakup than the strutted design of similar aircraft.

An Overview of Aircraft Accident Investigation and Component Failures

This article focuses on failure analyses of aircraft components from a metallurgical and materials engineering standpoint, which considers the interdependence of processing, structure, properties, and performance of materials. It discusses methodologies for conducting aircraft investigations and inspections and emphasizes cases where metallurgical or materials contributions were causal to an accident event. The article highlights how the failure of a component or system can affect the associated systems and the overall aircraft. The case studies in this article provide examples of aircraft component and system-level failures that resulted from various factors, including operational stresses, environmental effects, improper maintenance/inspection/repair, construction and installation issues, manufacturing issues, and inadequate design.

Situational Awareness and General Aviation Accidents

Situational awareness is a concept increasingly used in aircraft accident investigation reports. We analyzed 94 general aviation accidents in which situational awareness was mentioned by the National Transportation Safety Board investigator to determine factors that are significantly more often associated with fatality. We found a consistent use of the situational awareness concept, mainly applied to situations in which aircraft inadvertently collided with each other, with other man-made objects, and with various kinds of terrain. A significantly higher proportion of fatal accidents occurred during nighttime, in instrument meteorological conditions, or low visibility conditions. In addition, flights occurring during the cruise phase or in combination with spatial or geographical disorientation proved most often fatal.

Factors Contributing to Accidents During Aerobatic Flight Operations

INTRODUCTION: Aerobatic flight operations involve a higher level of risk than standard flight operations. Aerobatics imposes considerable stresses on both the aircraft and the pilot. The purpose of this study was to analyze civilian aerobatic aircraft accidents in Australia, with particular emphasis on the underlying accident causes and survival outcomes.METHODS: The accident and incident database of the Australian Transport Safety Bureau was searched for all events involving aerobatic flight for the period 19802010.RESULTS: A total of 51 accidents involving aircraft undertaking aerobatic operations were identified, with 71 aircraft occupants. Of the accidents, 27 (52.9) were fatal, resulting in a total of 36 fatalities. There were 24 nonfatal accidents. In terms of injury outcomes, there were 4 serious and 9 minor injuries, and 22 accidents in which no injuries were recorded. Fatal accidents were mainly due to loss of control by the pilot (44.4), in-flight structural failure of the airframe (25.9), and terrain impact (25.9). G-LOC was considered a possible cause in 11.1 of fatal accidents. Nonfatal accidents were mainly due to powerplant failure (41.7) and noncatastrophic airframe damage (25). Accidents involving aerobatic maneuvering have a significantly increased risk of a fatal outcome (odds ratio 26).DISCUSSION: The results of this study highlight the risks involved in aerobatic flight. Exceeding the operational limits of the maneuver and the design limits of the aircraft are major factors contributing to a fatal aerobatic aircraft accident. Improved awareness of G physiology and better operational decision-making while undertaking aerobatic flight may help prevent further accidents.Newman DG.

Responsibility of Airlines Company to the Passenger After The Ratification of the Montreal Convention 1999 by Indonesia

Aviation is a strategic business owned by a country, whether managed by a state company or a private company. In Indonesia, airplanes are the most important transportation. It is said to be able to connect every city, province, and inter-island very quickly compared to land and sea transportation. The importance of air transportation must be accompanied by regulations that guarantee the safety and security of airlines and passengers who are users of air transportation services. The security and safety are regulated through national and international rules which must be followed by every airline and passenger for the creation of good aviation business. The main problem in the aviation business is aircraft accidents which result in aircraft destruction and death to all passengers and crew members. This cannot be avoided because the cause of the accident could be from aircraft engine damage, weather, or error from the pilot. This aircraft accident not only damage airlines that have planes worth billions of rupiah but can damage passengers and heirs. Due to the risks involved in the aviation business. Although it is said that air transportation is very safe because the technology used by aircraft is the latest, accidents can not be avoided if it occurs.

An expert system framework to support aircraft accident and incident investigations

ABSTRACT The International Civil Aviation Organisation (ICAO) audits its Member States for safety oversight and monitors its Effective Implementation (EI). The global average EI was 68.83% in 2019, with 46% audited Member States achieving 75% EI (2022 target); however, an ICAO (2016 – 2018) audit highlighted six Annex 13 non-compliance issues. One issue was that more than 60% of Member States do not have a comprehensive and detailed investigator training program, contributing to many shortcomings that include a lack of essential and volatile evidence preservation, investigation management, investigation reporting and/or safety recommendations. This paper proposes an Expert System that captures knowledge in aircraft accident investigation generated over many years and allows aircraft investigators to share, access and interrogate accumulated knowledge to support the aircraft accident investigation process. The Expert System will improve the evidence analysing timeline, conclusion consistency and accuracy and support the on-the-job “field” training of evidence analysis through self-discovery.

The impact of psychological factor on the aircraft operation safety

Awareness of the radio exchange problems and the robust skills of recognizing and eliminating errors in radio communication will help to free up time and attention for the pilot and air traffic controller (ATC) to efficiently carry out their main professional functions in any circumstances. It is vitally important for pilots and ATCs in stressful situations not to focus their attention on the foreign language interaction that is the activity that only accompanies their main job performance. Analysis of aircraft accident investigation reports shows that language-related accidents mostly have psychological nature. The authors suggest a range of mental and psychophysiological qualities that determine professional competence and reliability of pilots and ATC. They also identify the sources of neuropsychic stress in critical situation and the ways to overcome it. The research results enable to design a language training model based on the analysis of the last-minute records and aircraft accident and incident reports to be able to identify typical problems of radio exchange, fatal language errors which led or could lead to a disaster. The research is aimed at improving aircraft operation and eventually increasing flight safety.
