Have Population Increases Of Large Birds Outpaced Airworthiness Standards For Civil Aircraft?, Richard A. Dolbeer, Paul Eschenfelder Feb 2002

Have Population Increases Of Large Birds Outpaced Airworthiness Standards For Civil Aircraft?, Richard A. Dolbeer, Paul Eschenfelder

USDA Wildlife Services: Staff Publications

Bird-aircraft collisions (bird strikes) are an increasing safety and economic concern to the USA civil aviation industry, costing over $400 million each year. One approach to reducing risks associated with strikes is to require commercial aircraft components to meet certain standards of safe performance in the event of a bird strike. The Federal Aviation Administration has developed airworthiness standards for airframes, windshields and engines using a single 4-lb (1.82-kg) bird mass as the maximum that must be tested (with the exception of a single 8-lb bird for the empennage, 6-lb bird for certain mid-sized engines that may be developed in …

Habitat Management Approaches For Reducing Wildlife Use Of Airfields, Scott C. Barras, Thomas W. Seamans Feb 2002

Habitat Management Approaches For Reducing Wildlife Use Of Airfields, Scott C. Barras, Thomas W. Seamans

USDA Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose safety risks to aircraft and cost civil aviation over $390 million annually in the USA We reviewed published studies to summarize findings on habitat management techniques that have shown potential for wildlife strike reduction. Habitat components that may attract wildlife to airports include food, cover, water, and loafing areas. Although maintaining tall herbaceous vegetation on airfields may reduce the attractiveness of loafing and feeding sites for some species of birds such as gulls, this strategy may also increase cover and food resources for other hazardous species. Thus, optimum vegetation height management strategies require further research …
