ELEVATOR SERVO CONTROL OPERATION
RE-CENTERING MODE
When the elevator servo control is in the re-centering
mode;
It is pressurized, both solenoid valves are
de-energized and no command signals are provided to
the Servo valve.
Due to the centering device the servo control actuator
is maintained hydraulically in its neutral position.
