PITCH CONTROL WHEEL STEERING FORCE TRANSDUCER - ADJUSTMENT/TEST
_______________________________________________________________
1. General_______
A. This procedure contains three tasks. The first task uses the F80218-42 test set for the adjustment of the pitch force transducers. The second task uses the DFCS BITE test for the adjustment of the transducers (airplanes with -912 and on FCC). You can use one of these tests to adjust the transducers. The third task is the pitch force transducer test.
B. Each control column has a pitch force transducer installed on the quadrant assembly. You can find the transducers installed opposite to each other, and they are electrically 180 degrees out of phase. This will decrease the null error voltage to the autopilot system.
