The Seattle Times article says FAA has briefed lawmakers that the software fix will:
- use input from both AoA vanes
- limit travel
- limit retriggering
Sorry if this has been covered before: how do the MAX of SWA and AA differ? Do they just have an AoA display or do they actually have an extra vane, and their MCAS is already configured to use that extra input?
Difference is display only. 2 vanes and exactly the same MCAS functionality as all other 737MAXs.
