So, how are they not?
- inferiorhuman 8y agoSo, how are they not? When you hit the trim buttons on the yoke MCAS stops for five seconds. What Boeing considers runaway trim would not stop when you counter with the trim buttons.
- blackflame7000 8y agoYea the interval is actually 20 seconds which is a really long time to a pilot thinking he is in an emergency. If you look at the period of the ups and downs of the Ethiopian flight they roughly correspond to that 20-second interval. Just when he thinks he's fixed it, it strikes again and again, taking a more aggressive nose down attitude each time.
- kayfox 8y agoSo, if the trim were running away based on an intermittent fault, the same situation could be encountered because the pilots don't need to execute the runaway trim checklist?
- Someone1234 8y agoIt feels different from their runaway stabilizer training. MCAS has a delay between each motion, whereas a runaway stabilizer is much more aggressive.
