Aircraft Equipment Problem Less Severe
Flight Crew Rejected Takeoff; Flight Crew Returned To Gate; General Maintenance Action
Aircraft
I was the Pilot Flying. During the takeoff roll on runway 17R; as the aircraft accelerated through 80 knots; I didn't hear the 80 knot call from the Pilot Monitoring. I called 90 knots to which I didn't hear a response. I looked at the First Officer's airspeed indicator and observed it indicating significantly less than mine; approximately 70 knots. I announced 'Reject' and rejected the takeoff. Approximately 95 knots was the highest indicated airspeed I observed in my indicator as we executed the Rejected Takeoff maneuver. The First Officer notified the Tower of our reject. We received initial taxi instructions after informing them that we didn't require any additional assistance. During our taxi to the ramp; an airspeed flag briefly appeared in the First Officer's airspeed indicator and then remained out of view. I informed Ramp Control that our brakes were heating and asked to be expedited. After approximately 10 minutes the marshaller began to direct us to our parking spot. Approximately 15 minutes after the RTO; we were chocked and able to release the brakes. The Brake Temp indicator illuminated with one brake temp of 5 as the highest reading. Maintenance informed us that we required one hour of brake cooling to which we agreed referencing the Recommended Brake Cooling Schedule based on our EICAS indication.
