No, it shouldn't be on a bus at all, nor on a RAT. It *should* have an
internal lithium battery backup so that it will continue operating even
if you rip it out of the aircraft, IMHO :-) So should the DFDR- even if
its inputs lose power and fall off-line, the recorder itself shouldn't
be the weak link.
