> And how is the acars still transmitting in a flat spin?
Do you still have AC 1 bus? If so, it can still transmit. If not, then no, it can't transmit.
If we're absolutely sure that AC 1 is dead in a flat spin, then we know that a flat spin can't be entered until the end of 0214. If we aren't sure, then maybe it can be entered earlier.
If a flat spin is incompatable with ACARS transmission, and we still believe that Bad Things(tm) happened around 0210-0211, then the Bad Things must not have included a flat spin.
