driver,
the flow of if/then logic in the system is lost with legacy and lack of a comprehensive logic flow chart.
As an example, the accident in DXB, when the pilots pressed TOGA, but then the ac bounced on the runway. The pilots had no idea of the logic switch in the system, and what was disabled with weight on wheels. The mantra, press TOGA, pull back...within 10 seconds the ac impacted the rwy.
The legacy commands, the if/thens, are lost in the FMS programming. Only on incidents, does the legacy and the myriad of if/then scenarios emerge.
MCAS was a poorly applied band-aid to a much larger problem. At least 3 different crews found the holes in the model, 2 of which, cant speak to the issues.
