This is par for the course for HN; smart people applying first-principle thinking on unfamiliar domains for about a minute, which confirms the biases of other outsiders who vote the plausible, but not-quite-right comments to the top.

This is par for the course for HN; smart people failing to interpret a comment in a charitable light, preferring instead to author a condescending reply in an apparent effort to score imaginary points at the expense of intellectually stimulating conversation.

Turbofans being slow to spool up is jets 101.
reply
So presumably OP never took jets 101. Neither have I. So what? The condescension remains unjustified and contrary to fruitful interaction. (See also the "lucky 10000" xkcd.)

This sounds about right to me, so I upvoted.

Lots of armchair experts incorrecting each other

HN is particularly notorious for armchair aviation experts. I am an aerospace engineer having worked in airworthiness & certification as well as maintenance/repair/overhaul on multiple different aircraft types both fixed and rotary. I mention this only to establish my bona fides as someone who knows their shit:

The comments here during the 737 MAX MCAS thing were fucking wild. So many randoms spitting out confidently incorrect nonsense.

Maybe that helps explain some of the fraction of HN that loves LLMs: they found their soulmates.

reply
The most ridiculous one was a poster who claimed that MCAS would run the trim at double the rate of the trim switches.

The trim motors only have 2 speeds - on and off.

HN is notorious for armchair <insert-topic> experts for <insert-topic> you actually know, outside of software, computing/computing-adjacent electronic hardware and startups. “Fucking wild” “confidently incorrect nonsense” is likely the norm on most fringe topics, judging by the few I know about.

That’s all forums in a nut shell. Any time you read about something you’re not personally familiar with it’s “look at all these people who know what they’re talking about… “, as soon as it’s something you are personally familiar with it’s “wtf are these people on about?!”

Not having handles where they should be at 1000 callout should have been an instant toga party.

That they passed their minimums and still weren't set up correctly is shocking, yes. How can you commit to landing instead of going around when you're not configured for landing?

The more egregious thing to me though is ignoring the GPWS callouts on approach because they were chasing the glideslope. If you can't maintain a stable approach, you need to go around, it's the first thing you learn.

You expect this behaviour from a first-timer in the sim, not a commercial cargo pilot.

> You expect this behaviour from a first-timer in the sim, not a commercial cargo pilot.

I'm curious - are commercial pilots reprimanded for doing a go-round after messing up the approach?

reply
No. They might have to say why they went around but they can't be punished for it (that's a great way to open yourself up to liability even stripping away all of the human elements). And I can't imagine any reason that an airline would truly care since they don't want their planes crashing so they don't want to discourage pilots from going around if they need to do so. The delay incurred is usually fairly small anyways, maybe 20-30 minutes.

However I will say that the majority of unstable approaches (97%!!) do continue to landing: https://flightsafety.org/wp-content/uploads/2017/03/Go-aroun...

...but I think that most of these unstable approaches are likely marginally unstable and only in one dimension. This landing was so far outside the realm of normal it's actually mind boggling that it actually happened. Pilots are trained to immediately go around without questioning it if many of the things that happened on this flight occur (such as not being in landing configuration well before touching down!)

> How can you comment as if you are knowledgeable enough about aviation to speak on this with authority, but you aren't aware that turbofan engines don't have instant throttle response and need time (up to 8 seconds) to spool up? I think a little more restraint is warranted in something like this if you don't know something that basic.

I'm a pilot, and I don't fly turbofans/jets. Not claiming any "authority", but qualified to comment... It's not "something that basic" unless you fly in that category, there's a lot more to aviation experience than knowing a fact about an engine you don't use. (But hey, congrats to you that you know it!)

> I think a little more restraint is warranted in something like this..

More restraint than saying "unclear <i.e. to me> why ...", an exact statement about what I didn't know, which harms no one and led to several informative explanations by people who know (most of them in good spirit)?

This is what good conversation is about.

...

Anyway, the point I was making holds and is this:

Orthogonal to whether they could/should have gone around at that point, and given that they stayed on the ground after all, it may turn out that that 4 seconds of indecision (instead of pure deceleration) may have directly contributed to the fatalities at the end of the crash.
