A requirements elicitation process for a purposeful general aviation (GA) aircraft design based on emerging economies.
Published In: “The Aeronautical Journal” through Cambridge University Press and The Royal Aeronautical Society UK in 2021
Abstract: Design success mostly depends on understanding and realizing product requirements, which are nested with different levels of stakeholders and specific market demands. Emerging markets are volatile and non-linear for understanding user-specific needs, particularly related to aircraft design. We attempt herein to elicit specific requirements through a proposed requirements elicitation process based on functional, physical, and behavioral viewpoints. An evaluation of those critical requirements is also performed through Quality Function Deployment (QFD) to reveal the fitness of the customer requirements (raw requirements) in relation to the technical measures. After selecting all projected potential users, a Systems Modelling Language (SysML) use-case diagram is also summarized to illustrate the user’s relation to the system functions. Some raw requirements are verified through constraint analysis and cost examination as an exemplary approach to present the transformation from raw to final requirements. The data are collected and analyzed to construct the aircraft’s key specifications. Most importantly, how to identify good requirements that define the needs, attainability, clarity, and verifiability are demonstrated.
In addition, it is demonstrated through this study that there is a need of a specific type of general aviation aircraft that may fulfil the unique demands of emerging economies by satisfying their socio-economic conditions.
Predicting the unpredictable: General Aviation (GA) aircraft cost estimation evaluation
Published In: “Journal of Air Transport Management” by Elsevier in 2022
Abstract: Cost estimation is an important part of project planning as well as research endeavors. Since the well-established cost estimation models used in the GA aircraft industry are already several decades old, a re-evaluation of their applicability to current market conditions is essential. Reliable cost estimation may also improve the chances to get external funding – a vital point for start-ups. To tackle this issue, we developed a research method to investigate potential cost models for GA aircraft that can serve as a guideline for, e.g., start-ups and research works. After gathering existing cost estimation models, they are classified and analyzed to find the ones most suitable for small aircraft. For evaluation purposes, the two most promising ones are applied to data from existing aircraft models to compare their accuracy, and finally, the best one is coded as an application in Python to improve usability. With our presented research method, we show a possibility to perform early cost estimation for small GA aircraft and offer a software tool to simplify its application.
