Civil Liability of The Air Carrier for Errors of The Aircraft Crew in Jordanian Law

The aircraft crew bears significant responsibility as they operate the aircraft in the sky, carrying numerous duties and exercising various authorities to perform their tasks effectively. The aircraft crew is obligated to fulfill their commitments towards the air carrier. Current study addresses the issues surrounding the extent of the air carrier's liability for errors committed by the aircraft crew. These errors may be personal, technical, or administrative during flight. We used a comparative, descriptive, and analytical approach to achieve the objectives of the thesis and answer its questions, which focus on defining the obligations and authorities of the aircraft crew and determining the nature of the air carrier's responsibility for errors of the aircraft crew. The key finding of study is that the Jordanian legislator has largely held the air carrier responsible for damages resulting from errors committed by the aircraft crew. Both the air carrier and the aircraft crew share responsibility for these damages towards third parties based on solidarity and mutual assistance. It is suggested to amend the text of Article (42/C) to include detailed provisions specifying the extent of responsibility for each member of the aircraft crew, the responsibility of the aircraft commander, operator, and air carrier in the face of actions leading to harm.

The technique for approximation of three-dimensional surfaces in order to synthesize algorithms for preventing aircraft collisions with obstacles

The work marks the beginning of the practical application of algorithms for making the aircraft recovery maneuver from three-dimensional constraint surfaces, which are a combination of terrain and artificial obstacles. An analysis of events leading to aviation accidents was carried out, and a comparison of on-board systems for preliminary notification of aircraft crews about collisions with natural or artificial obstacles was made. It is shown that such systems are insufficient due to their passive-recommendatory nature of issuing warnings. A question has been raised about the need to implement an active automatic collision avoidance system with spatial obstacles. In order to apply existing algorithms for the aircraft recovery maneuver from spatial constraint surfaces, a technique has been developed for approximating three-dimensional surfaces (obstacles) specified on a digital terrain map in the form of discrete height readings with a certain step on a coordinate grid. A paraboloid of revolution was chosen as a continuous 2nd order surface approximating the obstacle, and its characteristic parameters were determined. To determine the characteristic parameters of the paraboloid, an algorithm for determining the intersection of a three-dimensional surface and a plane, based on the principle of determining the intersection of triangles in space, as well as a method for selecting the inflection point of the terrain, based on determining the value of the terrain height gradient, are proposed for use. The construction of an approximating paraboloid using the example of a natural obstacle in the form of a mountain range is given. When synthesizing algorithms for preventing collisions of aircraft with obstacles, the need to take into account not only the parameters of the constraint surfaces and dynamic characteristics of aircraft, but also the accuracy characteristics of data sources about their position is noted. Promising application areas of the developed methodology are shown.

How can we simulate ionizing radiation at aviation altitudes from TGFs?

So-called thunderclouds, which are large dark clouds that are able to generate thunder and lightning, can act as natural particle accelerators, producing complex high-energy phenomena such as terrestrial gamma-ray flashes (TGFs) and gamma-ray glows. These events are often described through the mechanism of relativistic runaway electron avalanches (RREAs), cascades of high-energy electrons accelerated by atmospheric electric fields. Since the energies of the RREAs are up to several tens of MeV, they can also trigger nuclear reactions with atoms of the air and in the soil while entering the ground. Although these phenomena are intriguing, their lack of precise measurement and still not completely understood origins pose a significant challenge for assessing their impact on aviation safety. This paper introduces the project Research Centre of Cosmic Rays and Radiation Events in Atmosphere (CRREAT), aimed at providing measurements of TGFs, thunderstorm ground enhancements (TGEs), and other ionizing radiation phenomena during thunderstorms, as well as at aviation altitudes, stratosphere, and low Earth orbits (LEO). The paper argues that without accurate data on the origins and physical characteristics of TGEs and TGFs, it is impossible to reliably simulate their impact on aircraft crews and passengers. The paper also mentions how the general-purpose 3D Monte Carlo (MC) code PHITS can be used for future simulations and comparisons with measurements related to ionizing radiation phenomena in the atmosphere.

Analiza osobina subjekata krivičnih dela protiv Vojske Srbije određenih Krivičnim zakonikom

The Criminal Code of the Republic of Serbia recognizes individuals as perpetrators of offenses against the Serbian Armed Forces in a manner that, although linguistically similar to the way relationships are determined within the Serbian Armed Forces and the Ministry of Defense, fundamentally differs from the definitions provided by the Law of the Serbian Armed Forces. This may pose a challenge for authorized individuals leading criminal proceedings, as they often lack sufficient knowledge of the organization of the Serbian Armed Forces and struggle with its numerous regulations. The issue of legally defining individuals designated as perpetrators of criminal offenses by the Criminal Code is therefore explored through the method of content analysis and a comparison of regulations and broader scientific literature. According to the Criminal Code of the Republic of Serbia, individuals designated as perpetrators of criminal offenses against the Serbian Armed Forces include: military personnel; military superiors; subordinates; officials performing border duties; warehouse manager; citizen of Serbia; commander of a warship; member of a warship's crew; and member of a military aircraft crew. Through further analysis of the content of the regulations of the Serbian Armed Forces, clear definitions are provided for individuals such as subordinates, warehouse managers, citizens of Serbia, and members of a military aircraft crew in all comparative laws and regulations. Minor terminological deviations arise in the definition of the concept of military personnel, while some other subjects are significantly differently defined in the mentioned regulations (such as military superiors, who are actually individuals with the functional duty of a superior; officials performing border duties, who, since 2007, fall under the jurisdiction of the Ministry of Internal Affairs and cannot commit criminal offenses against the Serbian Armed Forces; or the commander of a warship and a member of a warship's crew, who can only be found on a military vessel).

MANAGING THE THREAT OF MANPADS USE AGAINST CIVIL AVIATION

The research results presented in this study concern selected aspects of the threat to civil aviation with terrorist attacks using the Man-Portable Air Defense System – MANPADS. The authors assess the possibility of the development of this type of threat, paying attention to several most important premises resulting from the suitability of using this type of weapon by terrorists against civilian aircraft. On the basis of the results obtained from the conducted research, the authors assess the current state of possession of this type of weapon by terrorist organizations in the world and indicate the main sources of obtaining MANPADS. The cases of incidents related to attacks on civil aircraft presented in the material indicate a high mortality rate of this type of events, the main victims of which are passengers and aircraft crews. The last part of the discussion is an overview of modern on-board systems designed to protect civil aircraft against MANPADS attacks, which they may soon be equipped with.

MODELING A NEGOTIATION PROCESS BETWEEN AIRCRAFT USING PETRI NETS

New air traffic control ideas are sought. Many studies point out the delegation of the responsibility for ensuring separation from air traffic controllers to the aircraft crews, but it should be assumed that the transition from centralized to decentralized air traffic control will occur in stages. It is, therefore, necessary to ensure effective communication between conflicting aircraft and to define the negotiation process between aircraft. The concept of the process of negotiation and communication between aircraft in conflict using a monotonic concession protocol is presented. The proposed solution was modeled using a Petri Net, which allowed us to analyze all the dependencies present in the system. The analysis allowed us to evaluate the method in the context of safety. The conducted research showed that, under the assumed conditions, the negotiation method allows obtaining the desired effect of negotiations while maintaining an adequate level of safety.

Method of training pilots of the latest-generation aircraft to interact with crews of other aircraft

Training pilots of latest-generation aircraft to interact with other crews in flight is complicated by the high level of cockpit automation and information overload of crews, on the one hand, and by the responsibility of pilots for decisions made regarding air traffic, on the other hand. Since the unified methodology for training pilots to interact with other crews in the same airspace is not available, the development of qualitative training is required. To address this issue, a method, based on a preliminary calculation of the amount of information which is necessary to process by a pilot when training depending on the type of this information for the efficient formation of a conceptual model of air traffic in flight, has been developed. The method of forming a conceptual model of air traffic is based on the application of a mathematical model of “random walk with absorption”. The method consists of three phases. In the first flight phase, a pilot should operate a training flight en route. In the first flight of the second training phase, a trainee evaluates the tendency for the approach (separation) of the assessed aircraft to the trainee aircraft. In the second flight of the second phase, the assessed aircraft position is determined by the crew position and altitude reports, in the third flight – by the crew position, heading and altitude reports. In the third training phase, when operating three flights primarily en route, a trainee is supposed to evaluate the air situation according to all the parameters reported by crews operating in the same airspace. After flights of the second and third training phases, the pilot is meant to analyze and evaluate the air situation while operating a flight comprehensively by the number of aircraft in the flight area, their position and the sequence of their motion. The experimental results made it possible to determine that participants in the experimental group were 24% more efficient in evaluating the air situation and interacting with other crews in flight in the same flight area compared to the control group pilots. Processing of the experimental results showed that when employing the proposed training method, the reliability of the latest-generation aircraft crew interaction at the automatic piloting mode was statistically significantly increased.

Evaluation of effective dose for gamma-rays of terrestrial gamma-ray flashes in aviation: spectral- and atmosphere-effects

Terrestrial Gamma-ray Flashes (TGFs) are intense and fast gamma-ray emissions, energy up to 100 MeV, generated within the Earth's atmosphere at altitudes below 20 km. Satellite observations indicate the TGFs are not a rare phenomenon, being produced on average at one per thunderstorm, yielding a global production rate of ≈35 TGFs/min within a latitude band of ±38°. Furthermore, the TGFs may coincide with the flight altitudes for several commercial aircraft routes, typically within the 10−14 km range, and thus cause passengers/crews unexpected exposure to large fluxes of high-energy ionizing radiation, namely for distances of the order of km.Herein, we introduce a novel approach based on a simple analytic/numeric methodology to estimate the TGFs gamma-ray emissions effective doses based on the differential fluence of photons at aircraft altitude and tabulated effective dose conversion coefficients versus the photon energy. For the first time, we examine the effective dose dependence on TGF's gamma-ray energy spectrum models found in literature and the atmosphere mass thickness crossed by the gamma-rays. Additionally, since the real irradiation geometry of the whole body in aircraft might be a combination of the several idealized geometries used in radiation protection, we considered beyond the typical anteroposterior (AP), the posteroanterior (PA), and the rotational (ROT) geometries as representative irradiation geometries in exposure to TGF gamma-ray's emissions.We calculated the effective dose versus the distance between the TGF site and the aircraft altitude (12.5 km) within the 0.1−5.0 km range and atmosphere mass thickness within the 3.3−213 g cm−2 range. Additionally, we calculated the average effective dose per fluence versus the atmosphere mass thickness crossed by the gamma-rays. At a distance of 1 km (34 g cm−2) and for the typical exponential cut-off power-law model (α = 1, EC = 7.3 MeV), the effective dose was within the 0.18−0.19 mSv range, being the respective average effective dose per fluence within the 10.8−11.6 pSv cm2 range. Moreover, for the variant of the exponential cut-off power-law model (α = 1, EC = 7.3 MeV, Emin = 1 MeV), the effective dose was within the 0.42−0.46 mSv range, being the respective average effective dose per fluence at 34 g cm−2 within the 12.7−13.6 pSv cm2 range.Generally, the data obtained agree with the scarce data found in the literature for similar conditions, evidencing the effect of the parameterization of the TGFs gamma-rays energy models, which may result in a 2- to 10-fold effective dose escalation. For the typical exponential cut-off power-law model (α = 1, EC = 7.3 MeV), the data obtained for an aircraft that passes through the vicinity of one TGF, with a distance of 1 km, points to an increase of the aircraft crew and passengers' doses of few tenths mSv over the cosmic radiation dose of few tens μSv along a typical flight of 6 h duration, representing ≈20% and ≈1% of the ICRP-2007 annual reference levels for passengers (1 mSv) and aircraft crew (20 mSv), respectively. More, with a distance of 0.5 km, the effective dose value is comparable with the annual dose for the aircraft crew due to the cosmic radiation for a typical yearly flight time of 500 h, representing ≈130% and ≈7% of the ICRP-2007 annual reference levels for passengers and aircraft crew, respectively.

About some trends in the development of air transport legislation

The article is devoted to the legal regulation of aviation industry. It is noted that a number of factors have led to changes in air legislation. Legislation has been improved in connection with the imposition of sanctions against the Russian Federation by unfriendly countries; in connection with the reform of monitoring and supervision. Over the years, efforts have been made to harmonize legislation. The changes were made especially actively in 2021–2023. Thus, the certification of developers and manufacturers of aircraft, unmanned aircraft systems and their elements, civil aircraft, engines, propellers, airworthiness issues, Maintenance and ground handling of aircraft. The changes also relate to the establishment of responsibilities of the Federal Air Transport Administration for the certification of the Armed Forces with the involvement of certification centers and testing laboratories; requirements for the approval of the Armed Forces to operation, to the certificate of airworthiness of the Armed Forces. The requirements for aviation specialists have been clarified, and new articles on the certification of members of the civil aircraft crew and civil aviation inspectors have been introduced. Monitoring of the application of new normative legal acts and their timely adjustment if necessary is required. Attention is drawn to the complexity of the laws adopted, in particular on unmanned aerial vehicles and on transport security. Further work is needed to improve air legislation.

Determination of the most dangerous flight modes of aircraft in icing conditions

In this paper, the object of research is the icing of aircraft surfaces during flight in the atmosphere. On many light aircraft, as well as on unmanned aircraft weighing less than 30 kg, there are no on-board de-icing systems. Nevertheless, aviation events occur with these aircraft, which are a consequence of their icing. Therefore, determining the most dangerous flight modes of aircraft in icing conditions is an urgent task. In view of the high cost of conducting flight tests and the impossibility of covering all possible events due to their potential danger, the complexity of creating flight conditions for aircraft in icing conditions on the ground, the mathematical modeling method was used in this study. To solve this problem, the analysis of the airworthiness standards of civil light aircraft, transport category aircraft, rotorcraft of normal and transport category was carried out within the framework of the work, the influence of various parameters on the thickness of ice build-up was investigated using a computational experiment conducted on the software developed by the authors of the article. On the basis of the results of the computational experiment, the dependences of the ice thickness on various icing parameters were obtained, a method was developed for determining the combination of heights and flight speeds of an aircraft, at which ice of the greatest thickness is formed on the surface of aircraft, other things being equal. Possession of this information will allow the aircraft crew and air traffic control specialists to avoid the most dangerous flight modes in terms of icing.

Radiation protection and estimate of commercial aircrew effective doses in Bosnia and Herzegovina.

Cosmic rays are the primary source of the daily exposure of aircrew and passengers to ionising radiation. This study aims to estimate the effective doses of ionising radiation for aircraft crews in Bosnia and Herzegovina by taking into consideration factors such as flight duration and altitude, as well as the geographical position of airports. The CARI-7 algorithm and neural network method were used in the analysis of data obtained from the Sarajevo International Airport. The results show that the estimated annual effective doses in 2021 range from 0.06 to 10mSv for flights to and from Belgrade and Dubai, respectively. Both linear regression and neural network models were developed to predict the effective dose based on flight duration, average altitude, latitude and maximum altitude. The findings reveal that flight duration is the most statistically significant factor, followed by average altitude, latitude and maximum altitude.

Verification of Estimated Cosmic Neutron Intensities Using a Portable Neutron Monitoring System in Antarctica

Many ongoing studies for predicting the production rates of cosmogenic nuclides, forecasting changes of atmospheric compositions and climate, assessing the cosmic-radiation exposure of aircraft crew, and the effects on precise electronic devices use numerical models that estimate cosmic-radiation intensities in the atmosphere. Periodic verifications of those models are desirable to be performed for assuring the reliability of the study outcomes. Here, we investigated an application of a portable neutron-monitoring system composed of an extended-energy-range neutron monitor and a small data logger for monitoring of cosmic-neutron intensities in a polar region. As a result of measurements in the east Antarctica region covering a wide range of altitudes (from 30 m to 3762 m) and comparisons with the model calculations performed with an analytical model based on comprehensive Monte Carlo simulations (PARMA), it was demonstrated that the portable neutron-monitoring system could be effectively applied for periodic verification of cosmic-neutron intensities that would improve the reliability of related studies.

Spinal injuries after ejection seat evacuation in fighter aircraft of the German Armed Forces between 1975 and 2021.

The ejection seat is one of the most important rescue tools for military aircrews. However, the high ejection speeds place high loads on the pilots, which is mainly absorbed by the pilot's spine. The differentiated evaluation of spinal injuries is of particular importance because this has a decisive influence on the further personal life and career of the affected aircrew members. Factors influencing the occurrence of a fracture as well as the impact of a spinal injury on military flight certification have not been addressed sufficiently to date. The authors conducted a retrospective evaluation of ejection seat evacuations in German Armed Forces combat aircraft accidents between 1975 and 2021. The total number of aviation accidents with ejection seat initiations and the survived ejections were collected. Accident-specific data and pilot-specific data were collected. In addition, it was evaluated whether aircrew members were recertified for military flight after the accident. The type of spinal injury and the location of the injury were evaluated. In addition to the descriptive statistics, two logistic regression models were developed to assess prediction values of accident- and pilot-specific factors for spine injuries. A total of 103 aircrew members were included in this retrospective analysis. The overall prevalence of spine injuries was 56.3%, and the overall prevalence of spine fractures was 33.0%. In the first regression model analysis, there was no association with pilot flight experience, age, height, weight, BMI, and being diagnosed with a spine fracture. Similarly, aircraft type, altitude, and airspeed were not associated with the occurrence of spine fractures. In the regression model analysis for predictors of rejection in military flight recertification after ejection seat evacuation, lumbar spine fractures were associated with higher odds of being rejected for recertification. Military aircraft crew members have a high risk of suffering from a spine injury after emergency evacuation using an ejection seat. In the subsequent medical workup, special attention should be paid to the spine, and ideally a consultation with a spine surgeon should be performed. Lumbar spine fractures may have major consequences for military flight certification, and therefore special attention should be paid to successful rehabilitation.

РАЗРАБОТКА НЕЧЕТКО-ЛОГИЧЕСКОГО КЛАССИФИКАТОРА ФАЗОВОГО СОСТОЯНИЯ ГИДРОМЕТЕОРОВ ДЛЯ АЛГОРИТМА КЛАССИФИКАЦИИ ЗОН ВЕРОЯТНОГО ОБЛЕДЕНЕНИЯ ВОЗДУШНЫХ СУДОВ В МЕТЕОЛОКАТОРАХ X-ДИАПАЗОНА

Icing is a dangerous meteorological phenomenon for aircraft and is a process of ice deposition on the external elements of the aircraft structure. In real conditions, the aircraft crew is not always able to quickly recognize the gradual deterioration of controllability, which usually occurs over a long period of time due to icing. This fact leads to emergencies. To prevent such situations, it is necessary to have timely and reliable information about the existing supercooled hydrometeors on the aircraft flight path, which will allow the crew to take preventive measures in a timely manner. The zones of probable icing are characterized by the presence of a large volume of super-cooled water in the liquid state. In the radar range, the liquid volume is characterized by the reflectivity of the meteorological phenomenon, and the phase state of water is characterized by the reflectivity and additional characteristics available only for radar systems with polarization processing of reflected signals. At the moment, there is no functionality for detecting supercooled liquid in the meteorological radars of the near airfield zone. The decision on the presence of icing can be made only on the basis of indirect signs and predictive models that do not have the necessary degree of reliability. This article proposes to use a radar that provides a full polarization scattering matrix of hydrometeors, which makes it possible to relate the characteristics of reflected signals to such parameters of hydrometeors as their size, shape, spatial orientation and dielectric state, from which one can proceed to practically important meteorological characteristics, including such, which cannot be obtained without taking polarization into account. Hence, the problem of detecting supercooled liquid water can be reduced to the problem of classifying hydrometeors. To solve this problem, the article pro poses a fuzzy-logical algorithm for the classification of hydrometeors specific to the phenomenon of aircraft icing and performed its initial training using simulation data. The effectiveness of the proposed classification algorithm has been analyzed. It is shown that the developed algorithm ensures the justification of the classification when observing hydrometeors in the case of dangerous icing of the aircraft of the order of 98%.

Optimization and verification of single pilot operations model for commercial aircraft based on biclustering method

Commercial aircraft crews have experienced a trend from five-person crew to dual-pilot crew. Arised from both technological and market demands, Single Pilot Operations (SPO) is considered an important development direction in modern aviation technology. In this paper, starting from Dual-Pilot Operations (DPO), the piloting process, decision-making process and decision-making mode of DPO for commercial aircraft are studied to obtain the operational requirements of SPO. Then, based on above analysis, the operational mechanism of SPO is studied and the core technology of SPO mode is proposed. Next, a new closed frequent bicluster mining algorithm named FsCluster is proposed for the optimization of the SPO model, and the other efficient bicluster mining algorithm named TsCluster is proposed for the analysis and verification of the SPO model. Finally, a typical flight phase scenario is modelled by Magic System of System, and combined with the proposed algorithms for analysis and verification to determine whether the SPO mode can meet the DPO requirements.
