ensuring the security in civil aviation - as a primary factor in economical and industrial development - is the major concern of international community. pursuant to the serious challenges in this sector after terrorist events of 11 september 2001 in the united states, international civil aviation organization (icao) as the most important organization relating to the international civil aviatio...

This study presents a dynamical systems model for long-term scenarios of demand in the aviation sector and resultant emissions of CO2 and NOx. We analyze the dynamics of demand growth for aviation, particularly in the emerging markets of developing nations. A model for subsonic aviation emissions is presented that reflects the consequences of industry forecasts for improvement in aviation fuel ...

This paper presents a new methodology, based on the probabilistic approach, for biorhythmic analysis to prevent aviation accidents. The methodology has been developed using the Gaussian distribution technique for reliability evaluation of the aviation system, keeping in mind the biorhythmic effects of the pilot. The normal distributed data of the US Air Force were tested and analysed based on t...

Today, wireless technology forms the communications backbone of many industries—including aviation, transportation, government, and defense. The era of the Next Generation Air Transportation System, (NextGen), is upon us. The Federal Aviation Administration, in collaboration with industry, is deploying NextGen technology on the ground, in the air, at air traffic control facilities and in the co...

The main objective of this study was to analyze anomalies voluntarily reported by pilots in civil aviation sector and identify factors leading to such anomalies. Experimental data were obtained from the NASA aviation safety reporting system (ASRS) database. These data contained a range of text records spanning 30 years of civilian aviation, both commercial (airline operations) and general aviat...

The basic purpose of aviation maintenance is to prevent the decreased levels of original aircraft airworthiness, safety and reliability design at the lowest cost, which is of great significance to the running of air transport enterprises. According to statistics, aviation maintenance accounts for approximately 20% to 30% of direct operating costs, not including indirect costs caused due to main...

Domestic production of general aviation (GA) aircraft has declined markedly in recent years and an effort is underway to revitalize this industry by opening new markets for aviation, shifting the perception of general aviation as recreation to general aviation as a travel option. This can be achieved only by providing a product that is safer, easier to fly in all weather conditions, and no more...

Deep and frequent Global Positioning System (GPS) signal fading due to strong ionospheric scintillation is a major concern for GPSguided aviation in equatorial areas during high solar activity. A GPS aviation receiver may lose carrier tracking lock under deep fading, and a lost channel cannot be used for position calculation until lock is reestablished. Hence, frequent loss of lock due to frequ...
