Maybe this is a language thing.... But I feel a confusion between "droop" and "adjusting Nr".
To me, droop is something that happens when the engine cannot deliver the amount of power required, hence the RPM drops.
(this is something we regularly test on maintenance flights... In oei conditions, pull pitch until the rpm drops....).
Adjusting or lowering rpm to maintain a certain power setting is not "droop" as far as I understand it...
Correct?
