Bird Strike / Risco aviário
Risco aviário (em inglês Bird strike) é, na aviação, o risco de colisão entre uma aeronave e um animal voador. Tais colisões, quase sempre fatais para o animal, podem causar acidentes aéreos.
O risco de ocorrência de um acidente fatal com um aparelho comercial é relativamente baixo: um caso por cada bilhão de horas de voo. Cerca de 65% das colisões com aves causam poucos ou nenhuns danos aos aparelhos. Os acidentes mais sérios ocorrem se a ave chocar com o pára-brisas ou se for aspirada pelos reatores. Este tipo de colisões com aviões civis gera anualmente, em todo o mundo, prejuízos que no ano de 2000 foram estimados em 1,2 bilhões de dólares.
A bird strike sometimes called birdstrike, bird ingestion (for an engine), bird hit, or BASH (for Bird Aircraft Strike Hazard)—is a collision between an airborne animal (usually a bird or bat) and a human-made vehicle, especially aircraft. The term is also used for bird deaths resulting from collisions with human-made structures such as power lines, towers and wind turbines (see Bird-skyscraper collisions and Towerkill). A bug strike is an impairment of an aircraft or aviator by an airborne insect.
Bird strikes are a significant threat to flight safety, and have caused a number of accidents with human casualties. The number of major accidents involving civil aircraft is quite low and it has been estimated that there is only about 1 accident resulting in human death in one billion (109) flying hours. The majority of bird strikes (65%) cause little damage to the aircraft; however the collision is usually fatal to the bird(s) involved.
Most accidents occur when the bird hits the windscreen or flies into the engines. These cause annual damages that have been estimated at $400 million within the United States of America alone and up to $1.2 billion to commercial aircraft worldwide.
