Task
Result
r. Move pilot cyclic stick to the right
approximately 3 to 4 inches. On pilot cyclic
stick FORCE TRIM switch, remove pressure
from FORCE TRIM REL position.
If cyclic stick does not remain in right position, replace
lateral (roll) magnetic brake (TM 1-1520-238-23).
s. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL. Move pilot cyclic stick
slowly to center neutral position.
If force trim does not disengage, go to
paragraph 11–14.
t. Move pilot cyclic stick (fig. 11–51) left
approximately 3 or 4 inches. On pilot cyclic
stick FORCE TRIM switch, remove pressure
from FORCE TRIM REL position.
If cyclic stick does not remain in left position, replace
lateral (roll) magnetic brake (TM 1-1520-238-23).
u. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL. Move pilot cyclic stick
slowly to center neutral position.
If force trim does not disengage, go to
paragraph 11–14.
v. Move pilot right directional pedal (fig. 11–58)
to approximately half way forward. On pilot
cyclic stick FORCE TRIM switch, remove
pressure from FORCE TRIM REL position.
If right directional pedal does not remain in position,
replace directional (yaw) magnetic brake
(TM 1-1520-238-23).
w. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL. Move directional
pedal slowly to neutral position.
If force trim does not disengage, go to
paragraph 11–14.
x. Move pilot left directional pedal to
approximately half way forward. On pilot
cyclic stick FORCE TRIM switch, remove
pressure from FORCE TRIM REL position.
If left directional pedal does not remain in position,
replace directional (yaw) magnetic brake
(TM 1-1520-238-23).
y. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL. Move directional
pedal slowly to neutral position.
If force trim does not disengage, go to
paragraph 11–14.
2. On pilot cyclic stick FORCE TRIM switch, remove pressure from FORCE TRIM REL position.
3. On pilot cyclic stick set FORCE TRIM switch to OFF.
4. Remove external power – electrical and hydraulic (primary) (TM 1-1520-238-23).
