How common is it for planes to hit birds?

Almost fifty bird strikes are reported daily on average. Only a fraction of those cause any significant damage. According to the Federal Aviation Administration, an average of 47 aircraft strikes are reported daily. The vast majority of those, some 97% of bird strikes, occur close to takeoff or landings.

While over 90 percent of the reported bird strikes occur at or below 3,000 feet AGL, strikes at higher altitudes are common during migration. Ducks and geese are frequently observed up to 7,000 feet AGL and pilots are cautioned to minimize en route flying at lower altitudes during migration.

Opening an aircraft door is impossible while the plane is at cruising altitude or above 10,000 feet due to air pressure. However, as the plane gets lower, experts say it is possible for a door to open as the pressure outside equalizes with the pressure inside the plane.

Birds of all shapes and sizes travel at speeds high enough that a window collision almost always proves fatal. Birds that survive immediate impact are stunned and often fall prey to predators, like domestic cats, soon after a collision.

Every airline has reporting criteria for pilots after a bird strike. Every US airline pilot is required to fill out FAA Form 5200-7 after a bird strike. This report is added to the Wildlife Strike Database, an up-to-date tracking platform used to determine the frequency and location of bird strikes in US airspace.

Your chances of being involved in a fatal plane crash are incredibly small – around 1 in 11 million, according to Harvard researchers. While your odds of being in a plane accident are about 1 in 1.2 million, survivability rates are about 95.7% – so the odds are with you no matter how you look at it.

The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.
