14. An Innovative Structural Fatigue Monitoring Solution for General Aviation Aircraft
ABSTRACT: This article proposes a novel and effective solution for estimating fatigue life of General Aviation (GA) airframes using flight data produced by digital avionics systems, which are being installed or retrofitted into a growing number of GA aircraft. In the proposed implementation, a flight dynamics model is adopted to process the recorded flight d

15. Residual Stresses Analysis in Ball end Milling of Nickel-Based Superalloy Inconel 718
Inconel 718 is widely used in the aviation, space, automotive and biomedical industries because of its outstanding properties. Near-surface residual stresses that are induced by ball end milling in Inconel 718 can be crucial for the performance and service time of the machined parts. In this paper, the influences of cutting conditions, including the use of c

17. Higher Education Aviation Programs in Greece: A Missed Opportunity or a Challenge to Meet?
Abstract: The air transport industry in Greece has been experiencing a significant growth. However, higher education has missed so far this export opportunity. Public universities and technological educational institutes have very limited undergraduate offerings in the fields of aeronautical engineering and aircraft maintenance technology, respectively. Thes

18. Climate Change and International Civil Aviation Negotiations
Abstract The International Civil Aviation Organization (ICAO) has discussed ways of regulating greenhouse gas (GHG) emissions by civil aircraft for almost 20 years. Over the past four years, a consensus has developed about a market-based mechanism in the form of a carbon offset system. This article describes the route to the agreement reached by ICAO’s 39t

19. Design Analysis of Solar-Powered Unmanned Aerial Vehicle
ABSTRACT One of the main problems in micro unmanned aerial vehicles is endurance or flight time since the general domain aircraft uses conventional fuel, which is a pollutant, has a limited life and is costly. Then, there is a huge demand for using an unlimited non-exhaustible source of energy. Solar energy is one of the unlimited available renewable energy

20. Hearing Health in Agricultural Aviation Pilots from Cindacta II Wearing Earplugs and a Helmet
Abstract Introduction Agricultural aviation pilots, exposed daily to intense vibration and noise, are likely to develop noise-induced hearing loss (NIHL). Objectives The aim of this study was to investigate the presence of audiograms consistent with NIHL in agricultural aviation pilots who use earplugs and helmets. Methods We conducted a cross-sectional

22. Crashworthiness Analysis and Evaluation of Fuselage Section with Sub-floor Composite Sinusoidal Specimens
Abstract Crashworthiness is one of the main concerns in civil aviation safety particularly with regard to the increasing ratio of carbon fiber reinforced plastic (CFRP) in aircraft primary structures. In order to generate dates for model validations, the mechanical properties of T700/3234 were obtained by material performance tests, and energy-absorbing resu

24. Flying in Clear Skies: Technical Arguments Influencing ANAC Regulations
Regulatory agencies possess the particularity of being controlled by non-elected politicians whose power is derived from delegations made by incumbent powers. There exists, however, a concern with the creation of institutional mechanisms that permit public participation, thus guaranteeing greater democratization and social control of the regulatory process.
