IFLY_INDIGO how come the airplane was in normal law after dual engine failure? FCOM says that if flight control computers detect G+Y hyd failure, it goes into alternate law. isn't it?
The report gives a clear answer:
The NTSB concludes that, despite being unable to complete the Engine Dual Failure checklist, the captain started the APU, which improved the outcome of the ditching by ensuring that a primary source of electrical power was available to the airplane and that the airplane remained in normal law and maintained the flight envelope protections, one of which protects against a stall.
