-an input lever with stops for stroke limitation.
-
two resolvers for engine control, electrically connected to the
relevant FADEC.
-
two sets of three plastic track potentiometers electrically connected to the SECs.
-A duplicate drive system for transducers.
-Four electrical plugs.
-
The input lever zero position is accurately determined by a rigging pin between input lever and body. The potentiometers are rigged to mid stroke and resolvers to zero for this input lever position which corresponds to idle selection.
-
The design is such that no single mechanical failure is able to cause the loss of the two potentiometer sets without loss of resolver drive.
-Potentiometer sets are the same as those fitted in SPD BRK control transducer unit and in side stick transducer unit.
-Each SEC control and monitoring unit receives signals from two potentiometers of the same unit, one of each set of potentiometer (to enable detection of a potentiometer drive rupture). Electrical characteristics of potentiometers are monitored by SECs as previously described for the other potentiometers. (Ref. Fig. 020) This figure shows mechanical liaison between the control unit and throttle levers on the center pedestal. (Ref. Fig. 021)
