pistons rarely run out of pedal, torque isn’t in great supply.
they do regularly run out of horses tho.

I disagree with the sentiment. It’s not unusual to have a “limit” that the pilot has to respect. An FLI simply combines several possible limits (NG, ITT/TOT, Torque for example) The “FLI” On an R44 is the MAP gauge. Of course the limit must be calculated for the atmospheric conditions.
The R44 has more installed HP than should be used at
sea level.
Long before it “runs out of HP” (RRPM droop), the MAP limit has been ignored, and the drive train has been abused.
