Narrative

OUR AIRPLANE HAD JUST COME IN. IT WAS OUR FIRST LEG OF THE DAY. I DECIDED TO DO A BATTERY START SINCE IT WAS ALREADY AFTER TIME XA20Z AND WE HAD NO POWER. #2 ENG BATTERY START WAS UNEVENTFUL. WE PUSHED BACK AND DID A CROSS BLEED START ON #1. TAXIED OUT TO RWY. DURING TKOF ROLL; I CROSS CHKED MY AIRSPD WITH THE STANDBY AIRSPD INDICATOR. IT READ ZERO. FO WAS THE PF ON THIS LEG. I CALLED ABORT; TOOK CTL AND REJECTED THE TKOF; NOTING NO AIRSPD ON STANDBY AIRSPD INDICATOR. WE HAD NOT REACHED THE 100 KT INCAPACITATION CHK. FO NOTIFIED TWR AND WE PULLED OFF THE RWY; NOTIFIED FLT ATTENDANT AND PAX AND COMPLETED AFTER LNDG CHKLIST. WE PULLED INTO A REMOTE AREA OF RAMP TO TROUBLESHOOT PROB.
