“…They aimed to calculate the total flight cost and did not need a very precise model for fuel consumption. In [39], fuel flow was modelled for a flight using BADA, integrating each of its composing phases starting from the departure gate and ending at the arrival gate. Then, a linear approximation for fuel flow as a function of altitude was considered, producing a model that can provide lower bound results for flight planning, but not considering the number of passengers.…”

Recently, there has been much interest in measuring the environmental impact of short-to-medium-haul flights. Emissions of CO2 are usually measured to consider the environmental footprint, and CO2 calculators are available using different types of approximations. We propose analytical models calculating gate-to-gate CO2 emissions and travel time based on the flight distance and on the number of available seats. The accuracy of the numerical results were in line with other CO2 calculators, and when applying an analytical fitting, the error of interpolation was low. The models presented the advantage with respect to other calculators of being sensitive to the number of available seats, a parameter generally not explicitly considered. Its applicability was shown in two practical examples where emissions and travel time per kilometre were calculated for several European routes in a simple and efficient manner. The model enabled the identification of routes where rail would be a viable alternative both from the emissions and total travel time perspectives.

“…The maintenance and safety of civil aircraft is of great significance in the management of civil aviation maintenance system, which can not only carry out maintenance and inspection of aircraft, but also ensure the safe flight of aircraft, thus reducing the accident rate of civil aircraft in operation 7 . Fault diagnosis involves modern control theory, signal processing and pattern recognition, computer science, artificial intelligence, electronic technology, statistical mathematics and other disciplines 8 . At present, in the process of maintaining civil aircraft in China, regular maintenance is mainly carried out with the help of the complete theory of parts, and maintenance should be carried out according to the situation without the help of equipment status monitoring.…”

The purpose of civil aircraft maintenance department is to ensure the airworthiness and safety of civil aircraft to perform various flight tasks, but the investigation of various mechanical or electronic failures of aircraft greatly limits the development of maintenance department. In recent years, civil aircraft accidents have occurred one after another, resulting in casualties and huge losses of property. A large part of the reasons for the accidents are attributed to the failure of civil aircraft. As a typical comprehensive and complex system, the complexity of its structure and working principle leads to the complexity of its fault symptoms and the relationship between faults and fault sources. In this paper, big data technology is applied to the airworthiness review model of civil aircraft to realize intelligent diagnosis of civil aircraft state. The simulation results show that the proposed civil aircraft fault location algorithm has strong information fusion performance, and has significant advantages over the traditional genetic algorithm (GA) in terms of false alarm rate and false alarm rate. Therefore, the model can be effectively combined to analyze the aircraft state and failure reasons in the airworthiness review of civil aircraft, and the quality management and safety management strategies of civil aircraft maintenance can be put forward according to the actual situation.

A deterioration cycle model is presented, designed to consider the turbomachinery efficiency losses that are expected during real engine in-service operations. The cycle model was developed using information from practical experience found in the literature to account for both short- and long-term deterioration effects; the former occurring during the first flight cycles, the latter due to regular in-service operation. This paper highlights the importance of analyzing the inter-turbine temperature margin () to track engine deterioration to determine the extent of an in-service engine life. The proposed model was used to assess the and fuel consumption impact in the CRJ-700 regional aircraft (powered by two CF34-8C5B1 engines) for three representative missions: short (0.4 h), average (1.4 h), and long (2.5 h), considering different levels of engine deterioration, from the new engine level up to fully deteriorated. The fuel consumption at the new engine level (zero deterioration) was validated against a real-time engine model embedded in a Level-D flight simulator, the so-called Virtual Research Flight Simulator located at the Laboratory of Applied Research in Active Control, Avionics, and AeroServoElasticity. The errors found in this validation for the trip mission fuel consumption in the short, average, and long missions were −3.6, +0.9, and +0.6%, respectively. The cycle model predictions suggest the for a new engine is 55.2 °C, whereas for a fully deteriorated engine, it is 26.4 °C. Finally, in terms of fuel consumption, the results presented here show that an average CF34-8C5B1 engine shows an increase in the cumulative fuel consumption of 2.25% during its life in service, which translates to a 4.5% impact in aircraft fuel consumption.
