Narrative:
On takeoff roll the airspeed indicators were erratic and inaccurate when checked passing through 80 KTS. I judged that continued takeoff was safer than a reject. We took off; climbed to 5;000 ft and stayed in the local area where we executed the 'airspeed: lost; suspect; or erratic' checklist. We then dumped approximately 3;000 pounds of fuel and returned to our departure airport for landing.
