The G4/5 Cl601/604 system redundance meets ETOPS requirements.
The 757/67/77 system redundance meets Etops
All have RATS or Abex backup electrical systems.
The Falcon 2000 has NO such back up electrical system.
The apu lites off in flight but funny thing is, it does too in the Gulfstrams except they give you TWO batteries to make sure it starts the Falcon 200 only gives you ONE. So you better be quick with that check list and lucky that it starts on the first shot because min bat voltage for APU start is 23v. Other wise all you did was drain down your ONLY bat.
