Most large commercial jet engines include design features that ensure they can shut-down after “ingesting” a bird weighing up to 1.8 kg (4.0 lb). The engine does not have to survive the ingestion, just be safely shut down.
What happens when a bird hits a jet engine?
What happens when a bird flies into a plane engine? Nothing, usually—most “bird strikes” don’t damage an aircraft at all. … If an engine fails, the pilot has to adjust the rudder on the plane’s tail in a way that creates an opposing force in order to drive the nose toward the functioning engine.
Do bird strikes destroy engines?
Since 1990 the FAA (Federal Aviation Administration) has compiled statistics on bird strikes. … In the majority of strikes, 85 percent or more, nothing happens: The bird bounces off the plane or a small bird…just goes through the engine and there’s no discernible damage [to the plane].
