(1) Measure the value necessary to move the throttle control lever between the IDLE STOP and the MAX CLIMB.
This value must be 0.85 and 1.05 daN.
This value must be 2.5 +0.1 -0 daN (5.62 +0.22 -0 lbf)
(3) If you do not get these values, adjust the artificial feel unit (Ref. AMM TASK 76-11-00-820-041)
Subtask 76-11-17-080-051-A ** ON A/C NOT FOR ALL (1) Measure the value necessary to move the throttle control lever between the IDLE STOP and the MAX CLIMB.
This value must be 0.85 and 1.05 daN.
NOTE: Measure this value in the IDLE STOP to MAX CLIMB range. Do not measure this value at the friction point where the load increases suddenly.
(2) Measure the value necessary to move to more than MAX CLIMB friction point. This value must be 2.5 +0.1 -0 daN (5.62 +0.22 -0 lbf)
