Narrative:
Flight was cleared by gso tower for takeoff. During takeoff roll I was monitoring engine and flight instruments. Approaching V1, captain called my attention to a single engine high wing aircraft at an altitude of approximately 50'-100' AGL (level) converging with us from left to right. Captain elected to delay takeoff rotation in anticipation of having to pass underneath the aircraft. Prior to crossing our path. The small aircraft Y made an abrupt 90 degree turn to the right and dove for the ground in an effort to avoid us, and in doing so, passed clear to our left. The local controller did not advise us of this traffic at any time, and when we asked him about it, he made a comment to the effect 'he didn't feel it would be a problem.' human factors consideration: early a.M. Operation, and poor controller judgement, controller request for us to expedite our takeoff due to an air carrier jet on final.

Title: MLG ON TKOF ROLL SPOTTED A SMA ON CROSSING PATH AND HELD TKOF DOWN UNTIL SMA TOOK EVASIVE ACTION. NO TRAFFIC INFORMATION FROM TWR ON SMA.
Narrative: FLT WAS CLRED BY GSO TWR FOR TKOF. DURING TKOF ROLL I WAS MONITORING ENGINE AND FLT INSTRUMENTS. APCHING V1, CAPT CALLED MY ATTN TO A SINGLE ENGINE HIGH WING ACFT AT AN ALT OF APPROX 50'-100' AGL (LEVEL) CONVERGING WITH US FROM LEFT TO RIGHT. CAPT ELECTED TO DELAY TKOF ROTATION IN ANTICIPATION OF HAVING TO PASS UNDERNEATH THE ACFT. PRIOR TO XING OUR PATH. THE SMA Y MADE AN ABRUPT 90 DEG TURN TO THE RIGHT AND DOVE FOR THE GND IN AN EFFORT TO AVOID US, AND IN DOING SO, PASSED CLEAR TO OUR LEFT. THE LOCAL CTLR DID NOT ADVISE US OF THIS TFC AT ANY TIME, AND WHEN WE ASKED HIM ABOUT IT, HE MADE A COMMENT TO THE EFFECT 'HE DIDN'T FEEL IT WOULD BE A PROBLEM.' HUMAN FACTORS CONSIDERATION: EARLY A.M. OPERATION, AND POOR CTLR JUDGEMENT, CTLR REQUEST FOR US TO EXPEDITE OUR TKOF DUE TO AN ACR JET ON FINAL.
