## Discrepancy

DURING TAKEOFF ROLL, CREW NOTICED NO AIRSPEED INFORMATION ON THE NR 1 PRIMARY FLIGHT DISPLAY.  THERE WERE NO ASSOCIATED WARNINGS OR ECAM MESSAGES.  THE TAKEOFF WAS ABORTED AT 100 KTS.  DURING THE REJECTED TAKEOFF, THE AIRSPEED INDICATION ON THE NR 1 PRIMARY FLIGHT DISPLAY RETURNED AND MATCHED THAT OF THE NR 2 PRIMARY FLIGHT DISPLAY.  CREW WAITED APPROXIMATELY 20 MINUTES TO COOL THE BRAKES AND THEIR SUBSEQUENT INVESTIGATION REVEALED NO FAULTS.  THE FOLLOWING TAKEOFF WAS NORMAL.  NO MAINTENANCE LOG WAS INITIATED.
