Narrative:

We were cleared for takeoff runway 29 oakland. The first officer was flying and the captain set takeoff power. The autothrottles were MEL'ed inoperative. Upon setting takeoff power; the captain and first officer both noticed an inaccurate presentation of airspeed. We were receiving a digital readout; but the airspeed tapes never came down. The takeoff was rejected at 100 KTS. We returned to the oakland ramp. We were told the pitot tube covers were still on. Maintenance performed an adiru check and returned the aircraft to service. The first officer recalled seeing the pitot covers installed but forgot to inform maintenance of the discrepancy. We departed 1 hour later. When the pitot tube covers were discovered on the plane; no one was near the aircraft at that time. The first officer continued the walkaround intending to alert someone to this situation. This never happened and we ended up rejecting the takeoff. I feel that in the future; if anything like this is ever found; to find or call maintenance personnel immediately; stop the preflight and take care of this situation. Alert the captain right away and then complete the walkaround.

Title: WIDEBODY FREIGHT ACFT REJECTED TKOF FOR AIRSPEED ANOMALY. PITOT TUBE COVERS WERE STILL INSTALLED.

Narrative: WE WERE CLRED FOR TKOF RWY 29 OAKLAND. THE FO WAS FLYING AND THE CAPT SET TKOF PWR. THE AUTOTHROTTLES WERE MEL'ED INOP. UPON SETTING TKOF PWR; THE CAPT AND FO BOTH NOTICED AN INACCURATE PRESENTATION OF AIRSPD. WE WERE RECEIVING A DIGITAL READOUT; BUT THE AIRSPD TAPES NEVER CAME DOWN. THE TKOF WAS REJECTED AT 100 KTS. WE RETURNED TO THE OAKLAND RAMP. WE WERE TOLD THE PITOT TUBE COVERS WERE STILL ON. MAINT PERFORMED AN ADIRU CHK AND RETURNED THE ACFT TO SVC. THE FO RECALLED SEEING THE PITOT COVERS INSTALLED BUT FORGOT TO INFORM MAINT OF THE DISCREPANCY. WE DEPARTED 1 HR LATER. WHEN THE PITOT TUBE COVERS WERE DISCOVERED ON THE PLANE; NO ONE WAS NEAR THE ACFT AT THAT TIME. THE FO CONTINUED THE WALKAROUND INTENDING TO ALERT SOMEONE TO THIS SITUATION. THIS NEVER HAPPENED AND WE ENDED UP REJECTING THE TKOF. I FEEL THAT IN THE FUTURE; IF ANYTHING LIKE THIS IS EVER FOUND; TO FIND OR CALL MAINT PERSONNEL IMMEDIATELY; STOP THE PREFLT AND TAKE CARE OF THIS SITUATION. ALERT THE CAPT RIGHT AWAY AND THEN COMPLETE THE WALKAROUND.
