Description
The rise up threshold for overspeed protection. The time for which this level is accepted is defined as
Starting Overspeed Time (page 245). This period starts to be counted once the RPM exceeds the value
Starting RPM (page 227). The threshold Overspeed Sd (page 244) starts to be valid once this period
elapsed.
The type of reaction of the overspeed protection within the Starting Overspeed Time (page 245) is
defined by the setpoint Starting Overspeed Protection (page 245), so it is either considered as Sd
Overspeed or unsuccessful start attempt. Then the next start attempt is enabled once the engine was
stopped. History record Starting Overspeed should be written in this case.
