They crashed because there were no experts in the cockpit.
You just posted something not in evidence. I have not seen anything about the jump seat pilot looking through a manual.
If he was looking for something that is supposed to be known and not on a checklist, that is more proof of sub par training.
maybe i misread, but the pilot in the jump sit wasnt worrying about flying the airplane. that was a plus, he just concentrating on finding out what was wrong. you could say the copilot should have done that, in the airplane that crashed, whatever.
I remember watching a documentary on airplane crashes, i dont really remember which airline but it was somewhre in south america similar to this.
https://en.wikipedia.org/wiki/AeroPeru_Flight_603pilots received incorrect stall and overspeed warnings and many others, the pilots were confused as to which instrument was giving a correct reading. turned out the altitude was the only one giving correct readings but they disregarded because they couldnt trust any instrument. airplane crashed.
in the documentary they asked this pilot that was analyzing the crash. he flat out said he wasnt gonna blame the pilots, they did what they could based on the info they had. he said based on the info i have now, i would have put the airplane in cruise control and wait for another airplane that was near by coming to help them sort the problem. but i was not in the airplane. cant really tell you for sure if i had done anything different had i been inside the cockpit.
some of you guys have typed responses that took you longer to think than the air lion or the the Ethiopian crash were up in the air. you have hindsight, they didnt. you have read news reports, and preliminary data , they didnt.
you could say I would have, should have, whatever, you were not there.
that's all i see, people blaming somebody when it was not a single thing that made the airplanes crash, it was several things.
anyway what do i know about airplanes.
