The Impact

The purpose of this study is to analyze standards as one of the main tools of protectionism in global markets of industrial goods. We use standards for modeling of market competition and adapt this approach for civil aviation markets. The role of local noise standards in civil aircraft markets is discussed. Imposition of more stringent aviation noise standards is modelled in the form of a two-person non-zero-sum game. Players are aircraft corporations that conduct research and development to reduce noise and lobby for stricter regulations in their controlled markets. The model can be used to predict that tighter aviation noise standards will be imposed and to justify the strategy of Russian aviation industry and science. The proposed approach can be adapted for other industries with strict regulations (in terms of safety, ecology). Such estimation allows us to assess whether it is in the country’s interests to participate in the standards race or not. It is shown that the equilibrium degree of standards tightening is higher if the players’ market shares are close to equal or individual players have advantages in the cost of production and/or product improvement is highly likely due to the company’s R&D progress.

Nationally, wildlife-aircraft collisions (wildlife strikes) have been increasing over the past 25 years; denoted in the National Wildlife Strike Database that has been maintained by the Federal Aviation Administration (FAA) since 1990. Increasing wildlife populations and air traffic coupled with quieter, faster aircraft create a significant risk to aviation safety; the cost to the civil aviation industry is an estimated $937 million dollars annually. USDA/APHIS/Wildlife Services (WS) provides technical and direct assistance to over 850 airports and airbases around the United States, including Chicago’s O’Hare International Airport (ORD). At ORD, raptors are one of the most commonly struck bird guild and accounted for at least 25% of damaging strikes from 2010-2013. An Integrated Wildlife Damage Management (IWDM) program is implemented at ORD to reduce the presence of wildlife on the airfield, consequently lowering the risk of wildlife strikes. Professional airport wildlife biologists at ORD concentrate much of their efforts on raptor management due to the high strike risk these birds pose to aircraft on the airfield itself. A variety of techniques are currently used to manage raptor populations at ORD. Concurrently, research is being conducted to evaluate the efficacy of the Red-tailed Hawk relocation program at the airport, as well as to assess their movements within the airfield environment.

Emissions Trading System

In order to combat climate change and control emissions in the aviation industry, it is necessary to research the aviation industry’s potential application of China’s Emissions Trading System (ETS), especially the carbon allowance allocation (CAA). On the basis of historical and benchmarking CAA schemes, considering the responsibility, capacity, and potential of firms, this study proposes the indicators CAA (ICAA) scheme. Moreover, considering firms’ costs, this study also proposes a multi-objective CAA (MCAA) scheme. Finally, the most effective scheme is reported. Results show that under ICAA and MCAA, caps are lower and basically consistent with the emissions reduction target of the “13th Five-Year Plan Work Program for Controlling GHG Emissions of Civil Aviation in China” and international goals. Different types of airlines gain different quotas according to their income and the number and age of their aircraft. The cost of reducing emissions in each scheme is less than 0.35% of their total costs. Under the ICAA-S, ICAA-P, and MCAA schemes, airlines can achieve a reduction in emissions of 19.7%, 20.9%, and 19.6%, respectively. Moreover, under MCAA, the difference in quotas between airlines is smaller. Therefore, of the schemes evaluated, MCAA is the most effective.

Inertial navigation has been in airline use for some five years and a substantial amount of experience has been built up. The system seems to have fulfilled the expectations of operators. In this paper, which was read at a meeting of the Institute in London on 8 January 1974 with the President in the Chair, Mr. Edwards of British Airways discusses its accuracy and the cost of ownership.In 1969 a paper was presented to this Institute by F. J. Sullings of the then B.O.A.C. which described some of the engineering aspects of INS and predicted in some detail the costs of operating such equipment for a fleet of twelve B747 aircraft. It is the purpose of this paper to refer back to those early predictions and to make comparison with what has actually been realized. Sullings also referred to the anticipated navigational accuracy of the equipment and this paper will demonstrate that the anticipated accuracies have consistently been exceeded since the first use of the equipment by B.O.A.C. in May 1970. Finally, since the equipment has now been in use for five years, it is considered appropriate to review some developments in which airlines are taking an active interest.

This study investigates carbon emission inventory from the local civil aviation industrys aircrafts, airport ground service vehicles and power consumption within an airport. With the existing data of five years, the operating costs probably added into civil aviation industrys operating costs are estimated and sensitivity of six variables are evaluated with Monde Carlo simulations herein to construct a basis for the policy of carbon trading. The dominant two factors contributing to variation in the cost of carbon trading per takeoff & landing at the Taoyuan Airport and the Taipei Airport are carbon price (71.1%) and number of takeoffs & landings (14.4%) as well as number of takeoffs & landings (38.7%) and carbon price (35.3%), respectively.

AbstractIntroductionNHS ambulance service conveyance rates in the UK are almost 70%, despite an increase in non-emergency cases. This is increasing the demands on crowded emergency departments (ED) and contributes to increased ambulance turnaround times. Yorkshire Ambulance Service introduced a specialist paramedic (SP) role to try and address this, but non-conveyance rates in this group have not been as high as expected.MethodsWe conducted a controlled interrupted time series analysis of appropriate non-conveyance rates in the 12 months before and after an SP primary care placement, using matched groups of patients cared for by SPs and control paramedics. A costing analysis examined the average cost per appropriate non-conveyance and the cost-effectiveness ratio between groups.ResultsBetween June 2017 and December 2019 there were 7349 incidents attended by intervention group SPs and eligible for inclusion. Following removal of cases with missing data, 5537/7349 (75.3%) cases remained. Post-placement, the intervention group demonstrated an increase in appropriate non-conveyance rate by 32.2% (95%CI 20.1–44.3%, p<0.001) and a reduction in the trend of appropriate non-conveyance relative to the control group of −1.8% (95%CI −3.5—0.0%, p=0.045).Post-placement, the cost per appropriate non-conveyance for intervention paramedics was a mean of £501.94 (95% bootstrapped CI £477.99–£526.46) versus £1217.89 (95% bootstrapped CI £1121.49–£1321.85) for the control group. This represents a mean saving of £715.95 per appropriate non-conveyance (95% bootstrapped CI £638.23–£795.69) for SPs compared to the control group, and a cost-effectiveness ratio of £2226.04 per percentage increase in appropriate non-conveyance (95% bootstrapped CI £1854.11–£2748.44).ConclusionIn this single UK NHS ambulance service study, we found a clinically important and statistically significant increase in appropriate non-conveyance rates by specialist paramedics who had completed a 10-week GP placement. This improvement persisted for the 12-month period following the placement and demonstrated cost savings compared to usual care.

India's aviation industry is largely untapped with enormous growth opportunities, provided that air transport is still expensive to most of the country's population, almost 40 per cent of whom are the upwardly mobile middle class. The industry will engage and work with policy makers to adopt effective and rational decisions to improve India's civil aviation industry. The primary aim is to identify the factors responsible for low sales of Air India. Secondly, the aim is to evaluate the causal relationship between factors identified and the dependent variable airline choice. It was found that Air India should reduce the cost of ticket on both domestic and international flights. Customer doesn’t find services delivered up to the mark. The quality of food, service of cabin-crew, lateness of flight and safety should be improved by Air India to remain competitive in the market. It has become and more imperative for the Air India to prove its mettle and not just settle on the taxpayers money bailed out by the exchequer but also on price, service and safety ground.

Based on the analysis of the current legislation, the system of subjects of interaction with the State Aviation Service has been determined. These include: the Ministry of Infrastructure of Ukraine (functional ministry), which includes the State Enterprise of Air Traffic Services of Ukraine, the State Enterprise of Air Traffic Services of Ukraine, the National Bureau for Investigation of Aviation Incidents and Incidents with Civil Aircraft, the State Aviation Regulation Department of Ukraine - bodies implementing state policy in civil aviation and the use of Ukrainian airspace. The following features inherent in the subjects of public administration in the field of aviation and the use of airspace of Ukraine: 1) the subject of public administration are both the executive branch and bodies that do not have such a status were endowed with the appropriate powers; 2) orderliness of the activities of all state subjects of regulation of the aviation industry in accordance with a single goal and strategic objectives, which are simultaneously synchronized with the main vector of development of the state. Among such general directions of development we can single out - European integration, economic strengthening of Ukraine, ensuring national security and defense; 3) the broad profile of the activity of state subjects of regulation is due to the fact that aviation is an integral part of the transport sector of the state; 4) taking into account, in carrying out regulatory activities, a large number of international standards, rules and requirements, which in turn implies the ability of the subjects of state regulation to actively work closely with foreign organizations; 5) the ability to integrate, ie integrated perception of the aviation industry and the use of airspace of Ukraine, which is technologically complex, is not limited to air transport, also includes production, repair and modernization, training, economic, land and other legal issues. 6) exclusion of commercial interests in the implementation of regulatory activities by state entities, while streamlining such activities in accordance with the economic interests of the state. It is noted that the field of aviation and the use of Ukrainian airspace is regulated by a large number of public administration entities, which form a complex and multilevel structure that does not benefit the development of this industry. Special emphasis should be placed on the different status of these bodies and the existence of duplicate powers in them. That is why today it is necessary to simplify the existing system as follows: 1. to ensure the independence of the State Aviation Service of Ukraine by obtaining a special status; 2. to subordinate to the State Aviation Service of Ukraine the National Bureau for Investigation of Aviation Incidents and Incidents with Civil Aircraft; 3. eliminate duplication of powers of public administration entities in this area.

The aim of the paper is to give an overview of the qualification requirements for future pilots in Canada and to discuss trends in such professionals training modernization. The methodological framework of the research is comprised of general scientific methods (analysis, synthesis, comparison, generalization – to study the works of foreign scientists, official and legal documents); specific-scientific methods (categorial analysis – to reveal the essence and clarify the definitions of the basic concepts of the study), and the structural and functional analysis – to determine the organizational, content and procedural features of pilot training in Canada. The analysis of the normative and legislative documents showed that the most professionally important licenses giving a pilot a professional right to work in the aviation industry and civil aviation are the Commercial Pilot’s License – CPL and the Airline Transport Pilot’s License – ATPL. The paper concentrates on the analysis of the requirements for knowledge and skills that a pilot has to possess and develop as well as a number of important steps to be completed to get the CPL and ATPL as specified in the corresponding sections of the Canadian Aviation Regulations. In order to obtain a license, a future pilot has to comply with the requirements for age, health status, a number of written examinations and flight training – flight hours, flight conditions and the level of skills. The qualification of a pilot can be attained at Flight Training Units or following the completion of university and college programs. The paper describes the specifics of integrated courses offered by the former – the Commercial Pilot Licence – Aeroplane (CPL(A)) integrated course, Commercial Pilot Licence – Aeroplane/Instrument Rating (CPL(A)/IR) Integrated Course, and Airline Transport Pilot Licence – ATP(A) Integrated Course. The conclusion is made that the types of flights and pilot activities in terms of CPL (A), CPL (A) / IR and ATP (A) licenses are largely the same. The difference lies in the number of hours provided for certain activity types and several specific requirements such as flying in difficult weather conditions or interaction between crew members. Among pilots’ training modernization trends we single out the following: its organization based on the competence approach, a reduction in the cost of training a new generation of pilots and increasing its efficiency through the introduction of new technologies in the training process.
