Flight Crew Rejected Takeoff
Aircraft; Procedure
After working to resolve several avionics problems with the aircraft involving the Thrust Management/Autothrottle system and the Takeoff Speed display; we attempted a normal takeoff. Upon reaching somewhere between 65 and 75 KIAS on my (Captain-pilot flying) side; the First Officer (FO) called '95 Knots.' I immediately performed a Rejected Takeoff and exited the runway. We did note that there was an airspeed discrepancy as we slowed. It appeared that the FO's was incorrect; as it did not seem as if we had enough time to accelerate to 95 KIAS compared to other takeoffs. After exiting the runway; all checklists and procedures were complied with and brake energy charts were cross-referenced. We taxied back to parking.
A B757-200 Captain rejected the takeoff at about 70 KTS when the First Officer called 95kts. Maintenance had worked avionics issues to resolve an autothrottle system and takeoff speed display anomalies.
