The term settling is certainly not in dispute, we could easily settle on a definition (Ouch!) but the idea that power settling means too little power is not just cross-wise to current usage, it is logically backwards.
In the case where you pull up the collective and not enough engine exists to cash the check, the term could be "falling through" which is a term we used in Vietnam to describe the foolish attempt to become OGE with IGE power.
This term also tells what it feels like, is not confused with any vrs/settling terms.
The concept of something being pilot error is not worthy of our consideration. Let he who is innocent cast the first stone. Today's helos provide precious little help to the pilot.
In Comanche and S-92, the torque gauge is marked with two variable indices which are computer updated. One marks the power available from the engines under current conditions (alt, temp, engine degradation), the other marks the power required to hover OGE under current conditions (alt, temp, gross weight). If the required is below the available, you are cool, and will not fall through. If not, try to not be terminating OGE.
