The master warning may sound, but that won’t actually tell you the exact nature of the problem. There are many accidents and incidents where the crew have heard the master warning sound, but have misidentified the cabin altitude warning when affected by hypoxia eg Helios 522, Payne Stewart’s Lear Jet, Kalitta 66, etc.

Which turns are you referring to? A constant magnetic heading from Banda Aceh with an inoperative left autothrottle, satisfies the satellite BTO/BFO data. The only turning that would occur is at fuel exhaustion of the second engine, when the autopilot is lost.
