What kinds of damage a bird strike can cause?
Bird strikes can inflict damage to not only on the engines of a large aircraft but to parts, including wings, nose, windshield, and fuselage, too. During landing or takeoff, bird strikes can cause damage to extended landing gear, which can lead to sufficient malfunction of brakes or nose gear steering systems.
How do you solve bird strike?
Delay takeoff or landing in the presence of bird activity. Below 10,000 feet, keep speed below 250 knots if operationally possible. Below 2,000 feet, climb at the maximum rate to reduce the flight time exposure to a strike hazard.
How does bird strike affect engines?
Bird strikes can lead to permanent deformations, sudden decrease of thrust, even engine failure during the flight. Bird strikes on rotating blades can also cause slices of birds hitting other parts which may lead to greater damages.
What airports can do to reduce the risk of bird collisions?
These include:
- Removing food sources, such as seed-bearing plants.
- Removing food sources for the insects that birds eat.
- Covering ponds with netting to prevent birds from landing.
- Destroying bushes and trees that offer attractive nesting sites.
- Maintaining the necessary grass level required at the airport.
What causes bird strikes?
Bird strikes may occur during any phase of flight but are most likely during the take-off, initial climb, approach and landing phases due to the greater numbers of birds in flight at lower levels. Since most birds fly mainly during the day, most bird srikes occur in daylight hours as well.
What happens during a bird strike?
During landing or takeoff, bird strikes can cause damage to extended landing gear, which can lead to sufficient malfunction of brakes or nose gear steering systems. In turn, it can result in directional control problems during a subsequent landing roll.
How do birds affect airplanes?
Most of the modern engines are required to be capable of ingesting birds that weigh about 1.8-kilo while running at full power. This means that even if both the engines are hit by large birds, it can provide a combined thrust output of at least one engine which is more than enough to return to the airport.
Why do birds do so much damage to planes?
As the bird strikes a fan blade, that blade can be displaced into another blade and so forth, causing a cascading failure. Jet engines are particularly vulnerable during the takeoff phase when the engine is turning at a very high speed and the plane is at a low altitude where birds are more commonly found.
What are the specific areas to be inspected in the event of bird strike?
When the aircraft is hit by birds during flight, the external areas of the airplane are inspected in the general area of the bird strike. If the initial inspection shows structural damage, then the internal structure of the airplane must be inspected as well.
Why do bird strikes happen?
What happens in a bird strike?
Normally, birds will hit the aircraft’s nose, canopy, wing, or engine – the forward-facing parts of the aircraft. If they hit the windscreen it has been known for the canopy to crack and the cabin to lose pressurization. Just one decent-sized bird can do that.
Is a bird strike an incident?
A bird strike is strictly defined as a collision between a bird and an aircraft which is in flight or on a take off or landing roll. The term is often expanded to cover other wildlife strikes – with bats or ground animals. Bird Strike is common and can be a significant threat to aircraft safety.
