SBAS and GBAS enhance standalone GNSS navigation to meet the safety and availability requirements of civil aviation. SBAS and GBAS are also freely available to other users, such as automobiles, buses, and trains on land as well as ships near shore. However, integrity as implemented there are significant differences between the aviation interpretation of navigation integrity and the one that wou...

In February 1912, the Surgeon General of the United States Army prepared a special preliminary physical examination for candidates who were to receive instruction in the Aviation Section of the Signal Corps. This examination and those devised over the next four years were too demanding and few candidates could pass. In response to the need to revise medical standards for aviators, Colonel Theod...

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question. The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR P...

Projecting risks posed to aviation safety by wildlife populations is often overlooked in airport land-use planning. However, the growing dependency on civil aviation for global commerce can require increases in capacity at airports which affect land use, wildlife populations, and perspectives on aviation safety. Our objectives were to (1) review legislation that affects airports and surrounding...

SEATTLE – Aviation Partners announced that as of 2:56 pm PST on Sunday, January 15, 2012 its blended winglets have saved the worlds commercial and business aircraft operators an estimated three billion gallons of jet fuel. This represents a global reduction in CO2 emissions of more than 32.2 million tonnes. Aviation Partners’ winglets are now flying on more than 5,000 individual airplanes, and ...

This study examines the impacts of emissions from aviation in six source regions on global and regional temperatures. We consider the NOx-induced impacts on ozone and methane, aerosols and contrailcirrus formation and calculate the global and regional emission metrics global warming potential (GWP), global temperature change potential (GTP) and absolute regional temperature change potential (AR...

Background The production of fuels and chemicals from renewable resources is increasingly important due to the environmental concern and depletion of fossil fuel. Despite the fast technical development in the production of aviation fuels, there are still several shortcomings such as a high cost of raw materials, a low yield of aviation fuels, and poor process techno-economic consideration. In r...
