NATOPS EXAM LATEST UPDATED
Takeoff/Max Torque - Answer: 100% Max
IDLE Torque - Answer: 1-10% (ground)
(Note: allowable torque range with Np stabilized and PCL at idle).
Transient Torque - ANSWER 132% Maximum (20 seconds)
(Note: 132% is the material limit above which engine damage may occur. A
torque above 102% indicates a system issue.
Takeoff/Max ITT - Answer: 820 Max.
Idle ITT - Answer 750 max.
Start ITT - ANSWER 871 - 1000 (5 seconds).
Transient ITT: ANSWER 821-870 (20 sec)
Takeoff/Max N1: ANSWER 104% Max
Idle N1 - Answer 60-61
(Ground).
67 min (flig
ht)
Transient N1 - ANSWER 104%
, Takeoff/Max Np (Avoid stabilized ground activities between 62 and 80% Np). -
ANSWER 100% Maximum
(Note: With the PMU turned off, a maximum of 100 +/- 2% is permitted.).
Idle Np: ANSWER 46 to 50% (Ground)
Transient Np - ANSWER 110 (20 seconds)
(Note: Permissible at any power setting to complete an in-flight emergency).
Takeoff/Max Oil Pressure: 90 - 120 psi
(Note: Normal oil pressure during steady state ranges from 90 to 120 psi; oil
pressure below 90 psi during flying idle or above indicates an oil system issue).
Idle Oil Pressure - Minimum: 90
Start Oil Pressure - Answer: 200 Max
Transient Oil Pressure - Answer: 40 - 130 psi
(Note: Only permissible during aerobatics or spins, and 15-40 psi for 5 seconds
while the PCL is idling).
Oil Temperature Takeoff/Max - ANSWER: 10 to 105 C
Takeoff/Max Torque - Answer: 100% Max
IDLE Torque - Answer: 1-10% (ground)
(Note: allowable torque range with Np stabilized and PCL at idle).
