What’s worse - sucking in a bird into a jet engine or a bird-scaring drone?

Sucking a bird into a jet engine, obviously. Was this a rhetorical question? The jet engine is mounted to a plane. It's designed to withstand bird strikes without exploding - they literally blast frozen turkeys into it with an air cannon - but they can still cause engine out situations that result in crashes or emergency landings and risk the lives of the hundreds of people on board. Not to mention the huge repair co…

He was pondering what's worse for a bird: extremely low occurance but surely instantaneous death, or getting to live knowing you'll be driven from your homeland to eventual extinction from robot invaders and wind turbines.

Interesting. But I’m getting tired of hearing the misuse of “teaching” in regards to software engineering. Unless the software is using machine learning, i.e neural networks, it’s not teaching. Genetic algorithm? Evolving. Anything else, programming.

Because he's a bird?

It is not obvious to me that a bird will flee from anything that approaches it, regardless of past experience, simply "because he's a bird". See above about city pigeons. Or aggressive geese at the park. Or birds that get sucked into jet engines because they apparently don't consider a jumbo jet to be an obstacle worth avoiding, hence this conversation.

Even city-dwelling pigeons have a personal space bubble that they will try to protect if possible. It may be just a foot or two but it is still there.

I don't think pilots would be entirely opposed to this kind of tech. While I don't think many pilots trust drone operators to be responsible in any way (I don't, since I don't think many of them know the airspace system or where their nearby airports are), they might be okay with unmanned aerial systems operated by the local airport authority, since they could likely geofence them in such a manner that they'd never c…

I'm not a pilot, but at 3000 feet AGL, you have a lot more room for emergency maneuvering / diverting back to origin or alternate right?

I remember hearing something about how many small aircraft incidents occur at low altitude on takeoff or landing, partly because it's harder to recover from a stall condition (perhaps engine-out as well?) at low altitude...

I like how there are three different interpretations of the question.

The smaller that bubble gets, the greater the chance of a drone actually striking a bird, which could become a major legal liability [1].

Wonder if this can be used to move bird flocks away from wind-turbines ?

It might be cheaper to enclose the blades' path in cages, or add more (possibly dummy) blades to make the path appear more filled, if that's been a problem.

Maybe a ring around the tips of the blades, and the blades double as spokes. They'd be ugly, but birds would fly into them less, and power output would get slightly smoothed by the weight shifted to the exterior of the wind wheel.
