Flight Crew Air Transport Pilot (ATP)
Aircraft Equipment Problem Critical
Flight Crew Rejected Takeoff; General Maintenance Action
Aircraft
As we began the takeoff roll the First Officer's airspeed did not come off zero and auto-throttles disconnected. Near approximately 80 KTS we recognized the First Officer had lost his CADC and I began a rejected takeoff procedure. First Officer advised Tower of our rejected takeoff. We exited the runway and began to assess the aircraft and our immediate needs. Plenty of runway was left and the brake temp was slow to rise. We called ATC and requested to return to the gate and also informed our Maintenance to meet the aircraft to perform all necessary inspections. Brake temperature never exceeded 205C and had already begun to cool down prior to parking at the gate. Taxi back to terminal was uneventful and info was entered into the [logbook].
MD-83 Captain reported losing First Officer CADC on takeoff roll; so the takeoff was rejected and the flight returned to the gate.
