In an out-of-trim emergency descent, what thrust setting is specified?

Explanation:
In an out-of-trim emergency descent you need enough rotor energy and control authority even when the aircraft isn’t trimmed for stable flight. Setting NR to 104% provides a deliberate margin above normal operating speed, helping the rotor maintain lift and responsiveness during the descent and reducing the risk of losing control as trim conditions change. Normal operation is around 100%, so this slight overspeed keeps the rotor from drooping and maintains the ability to recover or descend safely. Choosing a normal 100% would give less margin, and underspeed like 98% would reduce rotor responsiveness, while 102% is not the specified setting for this scenario.
