Flight Crew Rejected Takeoff
Aircraft
On takeoff; [we] advanced engines to stabilization EPR. Advanced throttles to takeoff and right engine did not spool up past 1.15 EPR. [We] received an ECAM and aborted takeoff. Exited runway; called Dispatch; Maintenance; and returned to gate.
While Captain was advancing throttles for reduced thrust (FLEX) takeoff; I noticed that the EPR for the Number 2 Engine stopped advancing past the initial stabilization checking EPR of about 1.1. Both throttles were advanced normally; but only the Number 1 Engine was advancing normally. Initially; I thought Number 2 was not advancing due to the Keep Out Zone and the high outside temperature which I had seen numerous other times in LAS. However; this time we also got an ECAM message and the Captain rejected the takeoff. He later told me he was also having difficulty maintaining directional control with the large difference in EPRs between the two engines. The ECAM message disappeared before we could see what it was. I notified Tower of our rejected takeoff; the Captain made the PA announcement for the passengers to remain seated; and the rest of the Rejected Takeoff Checklist was completed after clearing the runway and stopping the aircraft.
A319 flight crew reported they rejected their takeoff when the Number 2 Engine would not spool up beyond 1.15 EPR.
