212man,
The torque system on the S-92 is also radically different for twin-engine tasks. The limiters also support normal power pulls, so you make a takeoff using the limiter to regulate the power.
The gauge shows three power levels:
1) the power you are pulling, of course
2) an index that shows the power available at the current ambients from the engines in your aircraft, based on the automatically calculated power assurance.
3) the power needed to HOGE at the current ambients.

That way, you have in one place the power you are pulling, the power you can pull, and the power you need to HOGE.
Here is the basic patent:

It may be an overstatement that you can't overtorque the aircraft , since we pilots are very clever in our screw-ups, but the torque limits are set very high, typically on our helicopters at 150% for OEI and 135% for two engine levels, and the limiters stop you well short of these values.
