TORQUE %:
1. TO/Max
2. Idle
3. Start
4. Transient

1. 100%
2. 1-10% (ground); allowable torque range with Np stabilized and PCL at idle
3. ---
4. 131% (20 sec); torque at 131% is a material limit above which damage to the engine may occur. Torque above 102% is indicative of a system malfunction.

1. TO/Max
2. Idle
3. Start
4. Transient
