“…The most frequently used ones are the NASA method [16], the Association of European Airlines (AEA) methods [17,18], and one presumably originating from Lufthansa [19], which was last updated in 2010 [20]. Applications include technology unspecific studies such as in Lee et al [21] or Ali and Al-Shamma [22], where various conventional aircraft are assessed economically and compared to one another, as well as more specific investigations such as in Xu et al [23], Elham and van Tooren [24], and Pohya et al [25] where formation flights, winglet shapes, and hybrid laminar flow control are evaluated, respectively. An example of a debatable application can be found in Cuerno-Rejado et al [26], where a highly unconventional joined-wing aircraft design was compared to a conventional reference using the DOC approach.…”

Current practices for investment and technology decision making in aeronautics largely rely on regression-based cost estimation methods. Although quick to implement and easy to use, they suffer from a variety of limitations, both in temporal space and scope of applicability. While recent research and development in this area addresses these to a certain extent, aerospace engineering still lacks a flexible and customizable valuation framework. To this end, a generic environment for economic and operational assessment of aircraft and related products named LYFE is presented. This tool employs a discrete event simulation which models the product life cycle from its order through decades of operation and maintenance until disposal. This paper introduces its key characteristics and default methods alongside its modular program architecture. The capabilities are demonstrated with a case study of on-wing engine cleaning procedures which are triggered by a customized decision making module. Thereby, the impact on engine health, fuel efficiency and overall economic viability is quantified. On the whole, the framework introduced in this paper can be used to analyze not only physical products but also operational procedures and maintenance strategies as well as specified decision making algorithms in terms of their impact on an aircraft’s or system’s life cycle.

“…The actual cause of fuel consumption evolves from the engine and its thrust at the phase of flight. Fuel economy also depends on size and number of passengers, and as the quantity and the number of passengers increases, the operating cost per passenger reduces (Lee et al , 2019). Qu et al (2019) reported that Airbus A380 seems to be more fuel-efficient as compared to Boeing B747-400.…”

Purpose This research is associated with the real-time parameters of wide- and narrow-body aircraft to recognize the quantitative relationship framework. This paper aims to find the superiority of aircraft design technology which triggers the reduction in specific fuel consumption (SFC) and economic competitiveness. Design/methodology/approach The real case study is performed with 22 middle-of-the-market (MoM) aircraft. This paper develops a fuel burn mathematical model for mid-size transport aircraft by a multi-linear regression approach. In addition, sensitivity analysis is performed to establish the authentication of the fuel burn model. Findings The study reveals that the MoM aircraft would be the future aircraft design in terms of better fuel economy and carbon footprint. From the multi-regression analysis, it is observed that the logarithmic regression model is the best fit for estimating the SFC. Moreover, fineness ratio, aspect ratio, gross weight, payload weight fraction, empty weight fraction), fuel weight fraction, payload, wing loading, thrust loading, range, take-off distance, cruise speed and rate of climb are observed as the suitable parameters which provide the best fitness value as 0.9804. Originality/value Several existing literature reveals that a few research has been performed on the MoM aircraft with wide-body configuration. Moreover, mathematical modelling on the fuel consumption was insignificantly found. This study examines several parameters which affect the fuel consumption of a wide-body aircraft. A real-case study for design configurations, propulsive systems, performance characteristics and structural integrity parameters of 22 different MoM aircraft are performed. Moreover, multi-regression modelling is developed to establish the relation between SFC and other critical parameters.

“…Havayolları pandemiyi filo yapılarını düzenlemek adına bir fırsat olarak görmelidirler. Verilecek yeni uçak siparişlerinde operasyon maliyetleri göz önüne alınmalı, filo yapısı kararları bahsedilen maliyetlere göre verilmelidir [49]. Aynı 204 ortaklık grubunda yer alan havayollarının birbirine aktardığı uçuşlar göz önüne alınmalı, grup için verilecek uçak siparişleri ortaklıkta yer alan tüm havayolları için fayda sağlamalıdır.…”

Küresel çapta krize sebep olan COVID-19 virüsü havayolu kullanımını olumsuz şekilde etkilemiştir. Havayolları, sınırların kapatılmasıyla uçuş yapamaz hale gelmiştir. Kriz sebebiyle yolculuk talebi azalmış, uçuş rotaları kısalmış, uçuş sıklıkları azalmış, kullanılan uçakların ortalama ağırlıkları düşmüştür. Havayolları düşen talep karşısında kullanmadıkları uçaklarını Avrupa'nın dört bir yanında farklı havaalanlarına park etmişlerdir. Her havayolu filo yönetimi konusunda bazı kararlar almış, farklı tercihlerde bulunmuşlardır. İçinde bulunduğumuz pandemi koşulları her havayolunu farklı düzeyde etkilediği düşünülmektedir. Eurocontrol verileri doğrultusunda havayollarının filolarının kullanımlarının incelendiği bu çalışmada, Avrupa hava sahasında en yoğun uçuş trafiği yaratan ve en büyük filoya sahip 10 havayolunun filo kullanımları zaman serisi analizi yöntemi kullanarak incelenmektedir. Çalışmada amaç örneklem içerisine alınan havayollarının filo kullanımlarının farklı zamanlarda nasıl etkilendiğini gözlemlemek ve bu gözlem doğrultusunda bahsedilen etkilerin nedenleri doğrultusunda tahmin yapmaktır. Böylece havayollarının filo yapılarını tekrar gözden geçirme olanağı bulabilecekleri düşünülmektedir. Analiz neticesinde filo kullanımında en büyük dalgalanmanın Vueling ve Easyjet'te, diğer havayollarına nispeten en az dalgalanmanın Türk Hava Yolları (THY) ve KLM'de olduğu gözlemlenmiştir. Ortaya çıkan sonuçlar neticesinde havayollarına farklı öneriler sunulmuştur. Havayolları politik bağlarını gözden geçirmeli, hükümetlerle daha yakın ilişkiler kurmalıdırlar. Filo yapılarını gözden geçirecek havayolları yeni uçak siparişlerinde ortaklık yapılarına uygun siparişler vermelidirler. Uçuş ağlarıyla birlikte iş modellerini değiştirecek havayolları filo yapılarını, bu yeni modele göre kurmalıdır.
