2 Xdcrs(contains 4x triple potentiometers per axis).
FCPC1 & FCSC1 driven by separate linkage. (Dual Channel output 4 potentiometers, 2 unused) per axis.
FCPC2 & 3; FCSC2 driven by the other linkage (Dual Channel output 6 potentiometers) per axis.
The sidestick is placed in a polycarbonate container to prevent entrance of foreign matter.
The sidestick design is such that rupture, disconnection or jamming of any of the parts can't cause the loss of total A/F loads on one axis or block free movement of a set of a potentiometer group related to one axis.
Transducer output is monitored and compared, if any difference F/CTL L(R) SIDESTICK FAULT ECAM message is triggered.
