There is some margin in the calculations. But the training is very very clear, before V1 you must abort and after V1 you must continue. No discussion, no decision to make. You call V1, hands go off the throttles and no matter what you're going to fly.
The margin is for example that the plane must not just be able to fly, but also reach a minimum climb gradient to clear obstacles with a bit of safety margin. There is also an allowance for the time it takes from calling abort to actually hitting the brakes. And for example headwind is part of the calculation (it makes the takeoff distance shorter) but only 50% of the headwind is used in the calculations.
But all of those margins are not for the crew to use, the crew must just execute the procedure exactly as trained which means at V1 you're committed to continue the takeoff. And before V1 in case of an engine failure you have to hit the brakes to make sure you can stop before the end of the runway.
Maybe we should just stop commenting about whether or not something is AI generated. It doesn't add anything to the discussion, and is a waste of time.
An apology (in advance or afterward) doesn't absolve you of responsibility. And if you feel the need to apologize for something in advance, that's a huge clue that maybe you should stop yourself from doing the thing you've just apologized for.

Ok, sure!
As for the rest, "excuse me if I'm wrong" is a very common and valid phrase, though a bit ruined by sarcastic misuse
I attempted to show with it that I don't assume anything or default to hostility, though on a different occasion you'd yourself probably argue that others feelings are not my responsibility.
I'm not sorry for asking the question, unless t0mas88 got offended by it.
Finding oneself with the need to apologize in advance is an excellent hint to examine extra hard if you really should do what you're apologizing for. Apologizing when necessary is good, not having to apologize is much better.
It's a great level-up for characters of most alignments.
I did. By apologising and making a question, not accusation.
The commenter himself didn't seem hurt by it.
I'd recommend raising your outrage threshold.
I clearly am keeping this light hearted, while you go into fight mode because you saw the word "offence". Loosen up a bit :)
I see now that it probably wasn't, but "nothing" is an overstatement.
And knowledgeable and helpful responses can be AI, so there might be a fallacy somewhere in your offence-taking.
Are you offended when people do that in general, or only when they are wrong?
I do appreciate the effort put into writing a good comment.
> it probably wasn't, but "nothing" is an overstatement.
No, "nothing" seems perfectly accurate to me. I don't see even a single indication in tone, phrasing or punctuation that is a classic LLM giveaway.
It's offensive to standards of decency to question the authenticity of someone's speech, and it doesn't matter if you phrase it as a question or preface it with "excuse me if not". Unless there is really a strong reason to suspect something, which is absolutely not the case here. It's offensive when it's not warranted.
Absolutely not. There was genuinely nothing in their thoughtful and informative reply that seemed AI generated to me. Have you never seen people on HN write detailed, articulate answers? This was one of them.
Asking a question, getting a helpful response, and then implying it was written by AI is quite rude. Saying, "Excuse me if not, $SOMETHING_VERY_OFFENSIVE" does not make "$SOMETHING_VERY_OFFENSIVE" any less offensive! It's disheartening to see someone take the time to write a great answer only to be met with such a rude question. Please don't do that here. It's frustrating and discourages genuine contributors.
If it's absolute, then why add that?
Mine "to me" gave me a different impression, but it being a "to me", I questioned, not accused.
You perhaps recognize t0mas88 after all these years on HN. I don't. I'm relatively a new and infrequent user.
So I hope that I would be criticised just as passionately if that'd be a random user whose comments indeed turned out to be AI. Because no matter what is the fact, the question is rude, nay, very offensive.
Using AI isn't a tabu. It is fully debatable wether generating, reviewing and pasting helpful information on an informal forum is wrong, I just implied my own frustration with what I often experience.
Of course I could've phrased it much better, and I suspect you guys wouldn't bat an eye.

But regarding flight ability, wouldn't that be V2?
I thought there exist conditions where V1 is well below rotation speed.
Anyways,
> to make sure you can stop before the end of the runway
answers my main question, and makes sense from a procedural standpoint.
But still, hard to believe that there is no room for in-situ evaluation if runway overrun is worse than likely crash.
Of course then again, those have to be split second decisions.
