Of course the difference is, pilots have mandatory knowledge and training for all of an Airbus's "laws" including the direct mode that has no abstraction, i.e. joystick inputs directly translate to control surface deflections. Whereas with MCAS, pilots were not told about it, the operating manual has no mention of it, there was no training in sim based on it being upset due to a faulty angle of attack senstor, and most remarkably? No training with it disable via stabilizer trim set to cutoff. Appalling.
As a pilot and former CFI, without any question whatsoever, a pilot must know how the airplane behaves near stall. Student pilots have demonstrated certified pilot level competency of their particular make/model aircraft stall behavior, before any CFI feels comfortable doing a student pilot sign off for solo flight. It's that goddamn basic.
And 737 MAX airplanes have two such stall behaviors, with MCAS and without (via stabilizer trim cutoff). I'd like to see every Boeing pilot involved in these decisions put on a hot seat and asked if they really think it's appropriate to sign off a pilot, as competent to fly, when they aren't completely aware of two different stall behaviors for this aircraft.
In my opinion it's unconscionable to have deprived pilots of this knowledge. I am aware of the make/model type certificate arguments. As yet no authority has said for sure whether MCAS knowledge requirements would have then required a new type certificate, or if in fact MCAS is improperly papering over an airworthiness deficiency.
What we do know is, it's damn suspicious that this make/model has been grounded this long, with multiple supposedly official statements that software fixes are done and tested and should be ready for FAA approval and deployment any day now, and yet that's been postponed at least 3 times that I'm aware of. If this is strictly a software fix, and a mere tweak back to the original basis of certification, why all the delays?
