Boeing / 787 technical status before ETOPs Entry Point - redundancy requirements

[300-600]

I believe the 767 requires the crossfeed valve to be tested prior to EEP and cannot enter ETOPs airspace without it.

The 737 requires the same and the APU generator to be running (electrical redundancy requirement).

Part of our ETOPs training presentations suggests failure of two 787 Long Range Nav systems would preclude entry into MNPS airspace (but this is not shown in any of our official manuals).

Does anyone know of any equipment loss (apart from those checklist items that dictate divert to nearest suitable airport) which would preclude ETOPs entry...ie need to reroute non ETOPS or force a divert.

Thanks in advance
