1. An aircraft braking system comprising:
a first pedal pair comprising a first pedal and a second pedal;
a first pedal position sensor for said first pedal;
a second pedal position sensor for said first pedal;
a first brake control unit;
a second brake control unit, wherein said first pedal position sensor is operatively interconnected with one of said first brake control unit and said second brake control unit and said second pedal position sensor is operatively interconnected with the other of said first brake control unit and said second brake control unit; and
a first comparison module configured to compare a first output with a second output, wherein said first output is provided by said first brake control unit from an output of said first pedal position sensor and relates to a first pedal position of said first pedal, wherein said second output is provided by said second brake control unit from an output of said second pedal position sensor and relates to a second pedal position, and wherein said first brake control unit comprises said first comparison module;
wherein a first condition precludes operation of said aircraft braking system in response to displacement of said first pedal, said first condition comprising: 1) said first comparison module receiving said first output from said first brake control unit and receiving said second output from said second brake control unit; and 2) said first comparison module determining that said first output and said second output fail to comply with a first predetermined standard.
