How about they were at 1,000' descending 500'/min @ 70kts, pre landers and the tail goes?
Then as your EC135 experience has already told us, there is very little power demanded = Very little torque = Very little tail rotor authority needed.
That's exactly what you told us earlier isn't it? 70kts is flyable?
Are you saying he had/was 'going around' from an approach?
What would you do?
