Wait, wasn't MCAS used to fix two completely different flying issues, and weren't the changes introduced in the MCAS software twice, for two different points in the flight? Wasn't at least one crash caused by MCAS activation in the phase of the flight that was not even described in most of MCAS explanations initially (which reflected the decision behind the initial introduction of MCAS, not the later modifications)?
Therefore I believe the interpretation that MCAS "just augments" is too simplified from what it really was supposed to do. And the current "fixes" as they are implemented (still as to keep the "water not wet" there) could still leave plane as not behaving as it should, neither with MCAS active, nor when it is not active when it was supposed to be.
- salawat 6y agoMCAS was introduced to handle slackening Control surface response force at high AoA in high speed high AoA situations (Wind-up turns) and low speed high AoA situations (generally landing). That type of slackening would normally disqualify an airframe from use as a Civil Transport aircraft according to the FAA final report on the matter.
