How does airline's jet engines prevent birds and debris being sucked into the engines?
There's no debris in the air (except in the case of a volcanic eruption), and it's mostly luck that birds don't get sucked in.
They don't - it happens occasionally although there's very little debris on runways or floating around in the air. Unlikely a bird strike takes out all engines and often the jets can make it pretty well on just one engine. Look up US Airways Flight 1549 for and example of a bird strike that brought down a jetliner.
They don't.
That is why there are foreign object damages (FOD) events.
Runways are supposed to be kept clean, and engines are supposed to support the ingestion of the occasional small bird.
When you hit a bunch of large birds, then hope would have Cpt Chesley Sullenberger and copilot Jeff Skiles or people with comparable training in command, because you may have to walk or swim.
They DON'T. That's why bird strikes to the engines can cause an airplane to fail.
They don't prevent them.
They don't, conflict with birds is usually at low level and the areas around runways are supposed to be kept clear. Our bigger local airport has a "birdman" who flies a hawk over and around the runways. When the birdlife see THAT one overhead they flee and never come back. Runways and taxiways are inspected for other debris on a regular basis. In any case, these days a big twin is required to be able to continue the take-off and climb to safety altitude even if it loses one engine during the take-off run.
As it happens it's just on the news that an airliner in, I think, Russia has just lost BOTH engines from bird strikes during take-off and the pilots crash-landed it completely safely in a cornfield or something.
They don't. There were attempts at screens, but they iced up.
Birds are the #1 FOD damage to engines at lower altitudes. Planes have been forced down due to flameouts caused by them. See the movie "Scully".
Debris from runways is often kicked up by previous plane. Minimized by a reasonable delay in take off.
Engineers shoot frozen dead chickens, with air cannons, at running engines to see how well they handle birds.
They don't. Jet engines have to be certified to survive impact up to a certain size.
- Can airline pilots have service dogs/esa dogs? If so, do they bring them into the cockpit? It's just a question that popped into my head and when I looked it up I didn't see anything on it so I thought I should ask on here and see if anyone knows.
- What is the possibility of being in an airplane and the plane crashing? Kinda scared that with all the technology we have, there are still air plane crashes. i personally never worried about this but now that i'm thinking about the latest plane crash with the Ethiopian airlines that killed 157 passengers has me scared… Thoughts?
- I missed my flight, the airline is being difficult, can anyone So the airline is saying that I had enough time to catch my connecting flight, how ever my luggage is still at the airport. Wouldn't it have been transferred to the connecting flight if I had enough time?
- Is there an Airline just like Jet Blue? I took a flight from San Antonio to Oklahoma City one time. The flight and SEATS were AWESOME! I loved how big and comfortable seats were! All the other airlines I feel claustrophobic, The front seat in right in my face, no arm room. I thought I was going to have a panic attack last time I left Vegas on Southwest Airlines. Jet Blue no longer flies out of San Antonio. The closest place I would have to drive is Houston to catch a flight on Jet Blue to Vegas.
