Interesting - but the phrase "at landing" is a bit ambiguous.
It is certainly true that a RAT, as the name says, runs off ram-air pressure (airspeed) and will need some
minimum airspeed (130 knots in a 7
67) to produce useful output. So they would have lost the RAT power at some point in the final approach or roll-out, even if it was deployed and functioning for most of the event. And been on battery power alone from that point on.
