BIRDSFeathered Friends

The pilots on Air France flight 7775 ditched the plane after ingesting a bird in the number one engine. Why?

Good point.

I should have written “aborted the flight” NOT “ditched the plane”.

They didn’t “ditch” the aircraft. They followed fairly common aviation standards of regarding this incident.

“The aircraft (F-GMPG), on a scheduled flight from Pau to Paris Charles de Gaulle, was cleared for takeoff at 11:15am local time. The takeoff roll was normal. Just after the Fokker became airborne, a bird was apparently ingested into the number one engine. The flight crew chose to abort the takeoff, touched back down, but were unable to stop prior to reaching the end of the runway. The jet vacated the runway and collided with a passing truck, killing the driver. The airplane then slid to a stop in a field.”
-ref. AirDisaster.com

As to why this would happen:

1) Bird strikes can be very serious to an aircraft, a bird could easily damage or shutdown a turbojet aircraft’s motor. The air intake fans can be damage by reasonably small things. Even loose chunks of ice can damage an engine.

2) Take-off roll and lift-off are considered critical stages of flight. A dangerous situation developing during lift-off can be deadly, so the pilots choose to abort their take-off and put the aircraft back on the runway. However, they apparently, were going to fast to stop on their remaining amount of runway.

3) That aircraft has 2 engines. While an aircraft “CAN” fly with relative safety with one engine out…taking off with one engine out is not safe. Take-off has some characteristics that greatly differ from normal airborne flight. First, at take off, the aircraft will actually begin flying at a slower then required airspeed for flight because of something known as ground effect. Take offs are also periods of maximum thrust for an aircraft. If the pilots had tried to continue their take off, they would have had a lot of torque ‘twisting’ the plane as they departed. If they would have continued their climb out, they quite possibly would have experienced a stall and possibly spiral the aircraft…which would have been a much worse accident. They seem to have done the safest course of action they could in regards to aborting their take off.

Flight Feather $65.33 Flight feathers are the long, stiff, asymmetrically shaped, but symmetrically paired feathers on the wings or tail of a bird; those on the wings are called remiges (singular remex) while those on the tail are called rectrices (singular rectrix). Their primary function is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extrastiff rectrices of woodpeckers help them to brace against tree trunks as they hammer. Even flightless birds still retain flight feathers, though sometimes in radically modified forms. The moult of their flight feathers can cause serious problems for birds, as it can impair their ability to fly.

Bird Strike $74.88 A bird strike (sometimes birdstrike, bird hit, or BASH Bird Aircraft Strike Hazard) is a collision between an airborne animal (usually a bird or bat) and a manmade vehicle, especially aircraft. It is a common threat to flight safety, and has caused a number of accidents with human casualties. Major accidents involving civil aircraft are 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 but result in a great number of bird fatalities. 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. The term is also used for bird deaths resulting from collisions with man made structures such as power lines, towers and wind turbines.

Bird Migration $103.56 The aim of this book is to give a general overview of the whole subject of bird migration. After a chapter describing the Earths climate and ecosystem, the book is divided into three main sections. The first presents the life histories and migratory habits of nine different ecological categories of birds. The second section deals with the course and timing of the flight journeys, flight behavior, fuel economy, flocking, and the hazards from disorientation and predation. The final section covers the ways that birds navigate and shows that this process is still by no means fully understood. Author: Alerstam, Thomas/ Christie, David A.

Little Bird By Zullo, Germano $22.1 A man drives his truck up to a cliffs edge. Unable to go any further, he opens the back door of his truck and a flock of birds flies out, but, as the man soon discovers, a small timid bird remains.

Ani (Bird) $76.47 High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles The Anis are the three species of nearpasserine birds in the genus Crotophaga of the cuckoo family. They are essentially tropical New world birds, although the range of two species just reaches the U.S.. Recent DNA evidence places them in a new family, Crotophagidae.Unlike some cuckoos, the anis are not brood parasites, but nest communally, the cup nest being built by several pairs between 26 m high in a tree. A number of females lay their eggs in the nest and then share incubation and feeding.The anis are large black birds with a long tail and a deep ridged black bill. Their flight is weak and wobbly, but they run well, and usually feed on the ground. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.
