It's very easy to miss one alarm if there are several others going off simultaneously, which is highly likely if you've lost an engine due to a bird strike. Even if you hear or see the gear warning, you might be too cognitively overloaded to acknowledge and act on it.

the aviation term(probably others) for it is task saturation and loss of situational awareness.

Back in the day, there was a third crew member who was primarily tasked with navigation and monitoring systems.

Airlines decided it would be cheaper to cut that position and here we are.

Aviation is still much safer than back in the days where 3 or even 4 crew in the flight deck were standard. At some point the tradeoff between increased safety and increasing costs becomes unreasonable.

Manufacturers made planes that didn't need it, making their plane's TOC more attractive.

It's not that easy tbh - the advent of digital monitoring systems, fly-by-wire and glass cockpits plainly eliminated the need for it.

On the other hand EASA is pushing for research into single-pilot operations [1]... now that is nuts.

"here we are."

Here where precisely? Civil aviation is extremely safe in 2024, and this crash made worldwide news precisely because crashes are now very rare in the developed world.

If you demand 100 per cent safety, you are bound to be disappointed forever. Not even walking is 100 per cent safe.

I’m reading from aviation experts that the fundamental heuristic of “aviate, navigate, communicate” may have been forgotten as a result of panic following the bird strike incident (two minutes prior to the landing attempt). How should this principle have been executed in this situation?
Re:Jeju Air accident in South Korea kills at least 47 by harshreality on Sunday December 29, 2024 @04:50AM (#42538921)
Panic is understandable momentarily, but any professional pilot should be able to overcome that within a few seconds, and remember their training, which in an emergency is something like aviate, identify the problem if possible, and run checklists. Panic doesn't solve anything, and there's a comfort in having checklists and procedures to run. Something must have gone very wrong in training or with the plane for this to happen.

There's a standard short checklist for landing that includes flaps and landing gear. There may also be an emergency landing checklist that would also include those things.

The voice recorder and flight data recorder almost certainly survived. We'll know more after those have been recovered and analyzed.

I don’t want this to come across as second guessing a cockpit that I wasn’t in, but speaking generally, recover the aircraft to a flying condition (aviate), if not on a stabilized approach with high certainty of continuing to be (mostly aviate and some navigate), go around and hold at a safe altitude (A&N) while you run the checklists and assess the aircraft state (A) and tell ATC what your intentions are (communicate).

I don’t know what the exact state in that cockpit was, but the video of the aircraft sliding down the runway sans gear at a speed that looked well higher and well longer than normal touchdown suggests that they didn’t have a stabilized approach at the end, whether for good or bad reasons is something for the investigators to figure out.

Re:Jeju Air accident in South Korea kills at least 47 by weaksauce on Sunday December 29, 2024 @03:19PM (#42542703)
the airplane is perfectly fine to continue flying for a while on one engine so their momentary shock should not have been an issue. they've trained extensively for this kind of scenario and should probably have gone around if the bird strike happened on final approach. like the other person said... the voice recorder almost certainly survived and will give more information as to the root cause.
Re:Jeju Air accident in South Korea kills at least 47 by hbarka on Sunday December 29, 2024 @03:54PM (#42542991)
It may have been both engines out and there was not enough time to turn on the APU for landing gear deployment. The belly landing was executed just fine but tragically it was the wall at the end of the runway.
Re:Jeju Air accident in South Korea kills at least 47 by weaksauce on Monday December 30, 2024 @02:27AM (#42547315)
it wasn't the wall that got them actually it was the poorly designed ILS embankment that should have been ground level. but yeah you're right it is somewhat probable that it was two engines out as the evidence comes in

Isn’t the point of rigorous pilot training and selection to pick out those who will not be ‘cognitively overloaded’ by a dozen or two alarms at the same time, even under great stress?
Re:Jeju Air accident in South Korea kills at least 47 by cjbprime on Sunday December 29, 2024 @12:10AM (#42537694)
Not every country/airline has "rigorous pilot training and selection". There are, generally, not enough pilots.
Re:Jeju Air accident in South Korea kills at least 47 by MichaelZuo on Sunday December 29, 2024 @12:41AM (#42537850)
How is this relevant when the country, South Korea, is known?

It’s not a mystery where these pilots were licensed.

Re:Jeju Air accident in South Korea kills at least 47 by cjbprime on Sunday December 29, 2024 @12:55AM (#42537934)
It is relevant that the US requires ~6x more flight hours for airline hiring than South Korea, and the accident happened in South Korea, no?
Re:Jeju Air accident in South Korea kills at least 47 by AYBABTME on Sunday December 29, 2024 @03:08AM (#42538452)
Are you taking that number out of your arsenal or from a source? AFAIK most South Korean pilots are actually doing their training in the US, since it's much easier to accumulate the hours, and there's more GA. I would think their training is about the same as US pilots.

Although the US airways system is much more developed and used than Korea's, given that Korea is a smaller country and has an extensive bullet-train network. So I could buy an argument where US pilots just fly more.

Re:Jeju Air accident in South Korea kills at least 47 by cjbprime on Sunday December 29, 2024 @03:55AM (#42538649)
You should probably apologize for the suggestion that I am making up numbers.

The US FAA has required 1500 flight hours to receive an ATP (airline pilot) certificate since 2010: https://www.ecfr.gov/current/title-14/chapter-I/subchapter-D...

South Korea requires 250 hours as a country (6x), and Jeju Air specifically requires 300 (5x): https://epicflightacademy.com/hiring-requirements-jeju-air/#...)

Re:Jeju Air accident in South Korea kills at least 47 by AYBABTME on Sunday December 29, 2024 @04:28AM (#42538820)
Oh sure, I do apologize, just wanted to know if the numbers came from somewhere or if they were a wild guess. Thanks for bringing up the references.

The difference is drastic indeed. I almost would qualify for Jeju Air.

Re:Jeju Air accident in South Korea kills at least 47 by seanmcdirmid on Sunday December 29, 2024 @03:15AM (#42538476)
Most flights in Korea are international flights, so a pilot for Korean air probably flies as much as a pilot in the states. If the airlines need fewer flights, they could just go with fewer pilots rather than the same number of pilots flying less.

In the 1990s Korea and Taiwan had issues with accidents caused by military pilots without modern crew management cultures (“never question the captain”, which is a big no in modern commercial aviation), so they went with more career pilots trained from scratch (at American schools) rather than just transitioning military pilots into the role.

Re:Jeju Air accident in South Korea kills at least 47 by MichaelZuo on Sunday December 29, 2024 @01:29AM (#42538081)
Can you link the source for the flight hour difference?

If true it does have some signal but it’s not entirely persuasive. After all there clearly are midwit pilots too with a lot of flight hours, who just manage to scrape by on each step of the way.

Edit: Who may very well perform worse in extremus than a less experienced genius pilot.

Flight hours are not a good metric, experience does not imply skill.

Re:Jeju Air accident in South Korea kills at least 47 by throwaway48476 on Sunday December 29, 2024 @02:31AM (#42538342)
Flight hours are increasingly useless. The planes fly themselves enough that there are serious problems when something goes wrong and situational awareness is lacking.
Re:Jeju Air accident in South Korea kills at least 47 by Mawr on Sunday December 29, 2024 @12:50AM (#42537902)
Every single person's mind is going to become overloaded at a certain stress & task complexity threshold. Establishing where exactly that point is for a given person is difficult/impossible - e.g. throwing pilots into genuine life-threatening situations to test their responses doesn't seem ethical.
Re:Jeju Air accident in South Korea kills at least 47 by MichaelZuo on Sunday December 29, 2024 @01:31AM (#42538093)
Of course you don’t set the bar at that exact threshold, you set it higher so even after accounting for difficulties of assessment there would still be a comfortable margin.

The GPWS would literally be screaming "TOO LOW, GEAR" at you, over and over again. I find this difficult to believe. Being too distracted or overloaded to respond to it I can believe.

Re:Jeju Air accident in South Korea kills at least 47 by Roark66 on Sunday December 29, 2024 @04:49AM (#42538917)
Perhaps there are too many alarms in case of a bird strike in a modern airliner? "Hydraulic pressure LOW","Voltage in System B Out of SPEC", "Cabinets in the kitchen area Open", "and by the way,the landing gear is not down".

One would imagine there are psychology experts at Boeing and others who do nothing else all day ,but decide if one or the other alarm should be prioritised and at which volume (too low and they don't hear it, too loud and it disorients).

It is a complex subject. I think in time we realise removing the third crew member was an error.

Re:Jeju Air accident in South Korea kills at least 47 by aaronmdjones on Sunday December 29, 2024 @04:53AM (#42538929)
Most of those alarms would only be shown as text on the EICAS (Boeing) or ECAM (Airbus). Very few warning systems (the most important, like GPWS, TCAS, RAAS, the engine fire alarms, and the stall warning system) are aural and/or tactile in their annunciation.

EDIT: For a practical example, low hydraulic pressure in the left-hand system in a 777 would be yellow text on the EICAS that says "HYD SYS L".

Re:Jeju Air accident in South Korea kills at least 47 by cjrp on Sunday December 29, 2024 @08:26AM (#42539797)
