Narrative:

Air carrier X en route to clt on approximately 269 degree heading. TCASII of air carrier X observed intruder aircraft at 2 O'clock position and 3 mi and closing. Air carrier X aircraft at 6000 ft and intruder aircraft at 5500 ft and climbing. Captain of air carrier X aircraft was PF, turned right to approximately 330 degree heading and climbed to 6400 ft to avoid beech baron. Beech baron was flying VFR and not communicating with greensboro approach. Controller did not call traffic. TCASII RA, 'climb, climb.' would have likely been an accident without TCASII.

Original NASA ASRS Text

Title: NMAC BTWN A SHORTS SD360 ON A STAR ARR AND A BEECH BARON CLBING OUT. THE RPTR TURNED AND CLBED IN RESPONSE TO TCASII RA AND A SUBSEQUENT VISUAL SIGHTING OF THE OTHER ACFT.

Narrative: ACR X ENRTE TO CLT ON APPROX 269 DEG HDG. TCASII OF ACR X OBSERVED INTRUDER ACFT AT 2 O'CLOCK POS AND 3 MI AND CLOSING. ACR X ACFT AT 6000 FT AND INTRUDER ACFT AT 5500 FT AND CLBING. CAPT OF ACR X ACFT WAS PF, TURNED R TO APPROX 330 DEG HDG AND CLBED TO 6400 FT TO AVOID BEECH BARON. BEECH BARON WAS FLYING VFR AND NOT COMMUNICATING WITH GREENSBORO APCH. CTLR DID NOT CALL TFC. TCASII RA, 'CLB, CLB.' WOULD HAVE LIKELY BEEN AN ACCIDENT WITHOUT TCASII.
