It's not the same problem, as the engines responsed to thrust. The pilots applied thrust 8 seconds before impact, and the engines revved up to about 50% in that

- snom380 13y agoThat's exactly what I'm saying :)
- fnordfnordfnord 13y agoDo we know if that is a reasonable rate of acceleration for a 777 engine?
- mikeash 13y agoHighly knowledgeable people have commented on it and not said it was anything unusual, so, yes, I'd say it's reasonable. Jet engines don't change their output on a dime.
- fnordfnordfnord 13y ago>Highly knowledgeable people have commented on it and not said it was anything unusual, so, yes, I'd say it's reasonable. You know, there's not a single thing about your comment that's useful. >Jet engines don't change their output on a dime. Yeah, I know. That's the reason for the question.
- mikeash 13y agoWhat's not useful about that? Experts commenting on their field of expertise don't count for anything, or what? This specific item has been addressed by people who know this stuff. They didn't indicate it was abnormal. How is that not useful?
- fnordfnordfnord 13y ago>Highly knowledgeable people Who? You're some guy on the Internet. I should take it on faith that you can tell who is knowledgeable and who is a blowhard? > have commented on it and not said it was anything unusual, so, yes, I'd say it's reasonable. Again, instead of providing a fact I have to trust the judgment of a person I do not know. > Jet engines don't change their output on a dime. It should have been obvious from my question that I know that much about turbines. Do you have any information specific to 777 engines or something comparable? >Experts commenting on their field of expertise don't count for anything, or what? They might. It depends who they are. I don't always believe everything I see on television or the Internet. Sometimes I like to know their reasoning.
- mikeash 13y agoWhy the hell are you posting on an internet forum if you're not interested in what "some guy on the internet" has to say?
- nawitus 13y agoIt seems that regulations call for 6-7 secs from idle to full thrust. 1. http://www.pprune.org/archive/index.php/t-242588.html http://www.pprune.org/archive/index.php/t-242588.html
- fnordfnordfnord 13y agoThank you, that's the kind of answer I was looking for.
