Aircraft; Weather; Procedure; Company Policy
We departed gate late due to APU being inoperative and aircraft being repositioned to different gate. Completed all preflight duties; started engine at gate and had normal taxi out to runway. Tower cleared us for immediate takeoff due to landing aircraft on 3 mile final. As we took the runway and First Officer as flying pilot he selected toga thrust. At this point the autothrust disconnected and thrust was set manually. The aircraft accelerated normally. At the time of the eighty knot call; the Captain noticed the airspeed; altimeter; and the IVSI were inoperative with red flags. All F/O instruments were normal. The decision to reject was made prior to eighty knots but accelerated to approximately 100 KTS before thrust was fully retarded. Aircraft was stopped normally and exited with approximately 5;000 to 6;000 FT remaining of runway. Taxied clear at taxiway and went to ramp to check brake cooling chart since RTO brakes were operated. We reassured passengers of situation and amount of time spoke with Dispatch; Maintenance; [and] Operations. We returned to gate after brakes cooled and Maintenance found Captain's ADC failed.Equipment failure possibly due to hot aircraft with no APU and poor air circulation. Also the lack of ground personnel putting the ground air on the aircraft.
A B737-400 Captain rejected the takeoff when the Captain's airspeed; altimeter and IVSI indicated OFF because his ADC failed possibly because of no air conditioning when parked on the ramp in high temperature.
