FYI This is shown in the Lion air preliminary report.
They select flaps 0 (from flaps 5) and a few seconds later reselect flaps 5. Unfortunately a while after that they decide to go to flaps 0 again. With any flaps selected the MCAS system is disabled.
- js2 8y agoThis must have been mighty confusing without knowing about MCAS. It’s like trying to fly a black box instead of flying a plane.
- VBprogrammer 8y agoYeah, I can imagine. I mentioned elsewhere, the previous flight managed to develop a reasonable mental model (they thought that the Mach Trim System was responding to a wrong airspeed input). Saying that, failing to guess what's going wrong shouldn't result in a big hole in the ground. This is pretty interesting if you haven't seen it before: https://vimeo.com/159496346 https://vimeo.com/159496346
