The blowaway logic can be latched in either of two ways: a slow to moderate rotor decay rate to 100% Nr or an excessive decay rate of 5% per-second or greater occurring at 104% Nr or less. In both cases rotor droop is occurring because more power is being commanded than the engines can deliver at the takeoff power rating, but in the latter one, the logic is applied sooner to counter the faster rate, presumably related to a more urgent situation. Blowaway is reset over a ten second interval that is initiated when Nr is restored and exceeds 106%.
