Aircraft Equipment Problem Critical
Flight Crew Rejected Takeoff; General Maintenance Action
Aircraft
Flight was delayed for a few hours and tail swapped due to original aircraft being damaged in thunderstorm/windstorm. On takeoff roll (305;000 LBS; Flap 15) after 80 KT call; I observed a large orange OFF flag on Captain's Primary Altimeter. My immediate thought was of a possible pitot static problem due to previous storm. I also thought our speed was slower than it probably was and called reject. Shortly after initiating the rejected takeoff; I felt we were slowing with plenty of remaining runway and started manual braking. We taxied clear and coordinated with ground on a safe place to be without setting the parking brake. I asked the First Officer what he felt the high speed reached was and he said 110-120. I was surprised thinking it was closer to 100; but he is probably more accurate. We contacted Dispatch and coordinated with [Maintenance] and were advised to return to the ramp as the altimeter was not deferrable. Working with Ground we did a very slow taxi back to the ramp to allow the brakes/tires to cool. Highest temperature indicated was a 6 on one wheel. By the time we reached the ramp and parked it had cooled to a 5 or 4. Entered items in logbook and Maintenance started working what initially appears to be an ADC problem.
[Narrative 2 had no additional information.]
B767-300 flight crew reported they rejected their takeoff when the Captain's altimeter showed a flag at 110-120 KTS.
