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

This is classic short-sighted engineering hubris. Realistically how much statistical threat is there from birds? And how long until this design malfunctions somewhere? If this is rolled out in scale and put in use at every airport, it's going to happen.

>> The passengers on Flight 1549 were only saved because the pilots were so skilled. Of course the engineering and planning that went into the aircraft's construction had nothing to do with it, nor did the countless government regulations dictating safety equipment and training. These sorts of "miracles" happen rather regularly. A plane crashes near a runway totaling the aircraft, but everyone walks away. Piloting is…

all Airbus 320 will have the same safety mechanisms and industry required features, but they would have been useless without the pilotsquick response in the end

Human interaction ends up being the wildcard

I suspect the birds would eventually ignore the drones unless the drones are made to pose an actual physical threat to them. City pigeons are so accustomed to cars and humans that they barely move out of the way in time to avoid being crushed.

The drones would chase the birds away. And in cases when the birds are to be sucked by a jet's engine the autonomous drone would follow suit

> The drones would chase the birds away.

Chasing requires fleeing. If the bird knows from experience that the drone won't hurt him, then why would he flee from it?

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 cross paths with an aircraft. That said, low level wake turbulence from one of these aircraft could probably still wreck the drone if it carried off the side of the runway.

However, I doubt this would stop another near-disaster like Cactus 1549. They hit geese on climbout at nearly 3000 feet [0]. Thats pretty far outside of what a drone can enforce, or where I'd be comfortable having a drone flying. Current regulations prohibit them flying over 400 ft AGL, except within tight proximity to structures like radio towers.

For background, I'm a private pilot, not an airline guy.

Well sheep have been herded by dogs for millennia and I think it's pretty rare that they actually hurt any sheep.

The bird scaring drone can be programed to stay clear of planes. The birds can't

Birds are already programmed for that. It's called self preservation.

Airplanes are huge chunks of metal that make a deafening roar. Grown men are rightly afraid of coming near one.

Problem is downside risk: drones get hacked, or someone figures out how to make the drones fly into planes, or herd birds TOWARD planes.

As a society we've been pretty cavalier about algorithmic control. Which can work well for a lot of things. But probably shouldn't be trusted (without a TON of validation and regulation, as we've done over decades with airliners) with controlling stuff that can injure people or damage societies.
