Indonesian aircraft missing off Jakarta

[FCeng84]

The amount of nose down stabilizer MCAS puts in is a function of how far beyond the activation AOA MCAS senses that the airplane has gone. You have it correct that MCAS leaves that stabilizer increment in as long as AOA is high. The idea is that the nose down stabilizer increment will help the airplane recover to a more realistic lower AOA and thus should be left in place until AOA is reduced
