Bespoke:
Fly911, your explanation seems very involved compared to sandyelmets, have you actually experienced this failure?
Well, Sandyelmets explained the process using throttles but no collectine.
I was answering the following question by EBCAU:
Could you give us another option that would allow the safe landing of a "collectiveless helicopter" that would not involve the use of throttles?
No, I have never run into this situation while flying thankfully.
