What I dont understand is why the airlines themselves (Southwest and American) are refusing to halt the planes - this seems totally irresponsible with what is known at this point.

- twblalock 8y agoWhat is known at this point is that another 737 Max crashed for some reason, which might have been unrelated to the cause of the last crash, while being flown by an airline with a questionable safety record. If this turns out to have been a terrorist attack or something like that, a lot of people are going to have to eat their words, and millions of dollars will have been wasted for nothing.
- isostatic 8y agoAnd if it turns out to be a fault in the max’s design, operation, or training procedures?
- La1n 8y agoYou keep saying millions of dollars will have been wasted. However consider an other option where it turns out to be a problem with more airplanes and hundreds of of lives 'will be wasted'. Some countries take a more precautionary approach to risk than others where there is uncertainty, and I, personally, am happy to live somewhere that is willing to take the decision to prevent possible harm to human life instead of possible harm to (a relatively small section of) the economy, where there is uncertainty.
- jbm 8y agoNot a questionable safety record. Can we please stop assuming that African countries and airlines are all the same? https://thepointsguy.com/news/despite-recent-crash-ethiopian-airlines-has-strong-safety-record/ https://thepointsguy.com/news/despite-recent-crash-ethiopian...
- CaptainZapp 8y agoActually a lot of African airlines do have dodgy safety records and Africa is the unsafest continent to fly. That said Ethiopian is the shining exception and has, apart from a 70 year history, quite a stellar safety record.
- umanwizard 8y agoIt seems you’re directly agreeing with your parent comment’s point: not all African airlines are the same. Many are shitty; Ethiopian is not.
- sfilargi 8y agoIt’s pretty safe to assume that at this point every fricking pilot out there knows about MCAS and how to deal with it if this specific problematic behavior occurs.
- kalleboo 8y agoThat's what everyone said before the Ethiopian Air crash as well
- 4BxHkLgUVBG 8y agoBut not if you have 20seconds to recover?
- kirykl 8y agoIt's 2.5 degrees every 15 seconds. There's time to recover "MCAS will trim the Stabilizer down for 10 seconds (2.5 deg nose down) and pause for 5 seconds and repeat if the conditions (high angle of attack, flaps up and autopilot disengaged) continue to be met. Using electric pitch trim will only pause MCAS, to deactivate it you need to switch off the STAB TRIM SUTOUT switches." http://www.b737.org.uk/mcas.htm http://www.b737.org.uk/mcas.htm
- CydeWeys 8y agoIt's been happening during initial ascent, which is a very busy time of flight with little margin for error. Even if you are aware of MCAS, it takes time to recover, and you might not have that much time to spare.
