It’s not clear the AOA disagree light would have saved the two flights, so waiting for the next release was reasonable.
The critical jump pilots had to make was that this was a trim runaway event. AOA indicators were not connected to the trim system before.

- jdsully 7y agoThe FAA provides time to fix issues if its deemed to not be a critical issue - because if every problem results in grounding planes then people just won't report issues. The added stress of millions in losses could also result in subpar fixes that cause more problems. In this case I agree with the FAA's initial decision for this indicator. Its extremely unlikely having it working would have prevented the two crashes. The mere fact that it might have helped doesn't make the original decision incorrect.
- dagaci 7y agoIt seems that the MCAS (Maneuvering Characteristics Augmentation System) system depended upon the AOA.
- cottsak 7y agoYes but not in an absolute way. I think we can only assume that MCAS uses this as one of it's many inputs in order to determine it's flight control logic.
