Monitoring of the computation through duplication and vote of the mid value of the deflection order among three values: . command deflection order . monitoring deflection order . null order (stability order). This ensures the passivation of any erratic value and its elimination from the vote. The voter circuit includes comparators: . C3 comparator between the deflection order generated by one channel and the value finally voted. This identifies the faulty channel. . C1 comparator between the command and the monitoring voter. This comparator monitors the digital section of the computer.
-
Monitoring of the power channel through comparison (C2) between the deflection order and the position feedback.
-In-flight monitoring of the pressurization status of the hydraulic systems.
-Monitoring of the transducers (Ref. 22-65-00).

5. Test Procedure
______________
A. Computer At power rise, during the safety tests, the sections specific to the yaw damper and mainly the hard-wired engage logic, are validated.
B. Servo-Actuator This test is introduced to minimize the time of risk of hidden failures which can affect the standby channel. This test is used to check:
-
The electrical continuity of the current amplifier up to the servovalve by introduction of a non-executed fixed order (servo-actuator not validated)
-
The pressure switch between the electrovalves (capability to trigger) (which can be tested only with the hydraulic pressure applied).
R **ON A/C 106-149, 301-399, 401-499,
The pressure switch can be tested only with the hydraulic pressure coming from the engine.
