It is important to remember that the AoA miscompare alert
was not an option.
It is a
standard feature that Boeing knew was not working unless the optional AoA display was installed.
Boeing knew this for a significant amount of time -before- the Lion Air accident.
Had it been working on the penultimate Lion Air flight it might have led to fixing AoA sensor system before the accident flight.
