CONF iture;
I think that is the point RR_NDB wants to bring forward :
If the recorders have their own independent power supply, they will keep recording.
If that is RR_NDB's point, then he hasn't thought it through very well. He hasn't said what parameters the recorders will keep on recording and how that works.
The only suggestion of independent power supply that has emerged was after SR111 and that was the voice recorder.
