Essential DC is what I should have specified You're correct.
If the transponder had been powered/working, and ATC had been able to locate the aircraft, could the situation have been salvaged (in other words, could they have been directed to the airport and made a successful landing)? If so, would it be worthwhile to provide some sort of battery backup power to the transponder?
