E 5.3.15 CATEGORY 15, AUTOROTATION THRESHOLD
The following table provides identification of the Autorotation Threshold. Each entry in the ID column corresponds to an
engine torque threshold for autorotation. Each helicopter type has a unique engine torque percentage during autorotation
based on the aerodynamic qualities of the aircraft. This value is not typically published or well known, thus it has been
included as a configuration item in Table 10.3.15. Since a typical Autorotation Threshold value is between 5% and 10%, the
values have been chosen from 0% to 15% in increments of 0.5%.
