Narrative:

Flying IFR boca raton (bct) to falcon field (ffc), in dense cloud IMC, my skywatch (TCAS) showed rapidly closing target on intercept at 10 Oclock, target first scoped at 3 miles, 300 ft below. Attempted call to center stepped on. Target closed to 1.5 miles, 200 ft below when center reached. I requested instruction regarding intercepting aircraft. Center did not appear to understand my concern. I explained that target was less than a mile and apparently climbing, on direct intercept. After several seconds waiting ATC response, I informed center I was initiating urgent 500 ft climb to the right shortly afterward, target passed below me, showing 100 ft beneath on skywatch. Center informed me that separation was a full 500 ft. I remained in zero visibility (never saw other aircraft) for 3 more mins. Returned to assigned course within 5 mins. I was audibly alerted by TCAS, and in absence of clarification by center, took what I felt was appropriate avoidance action in zero visibility. Center was quite busy at that time, and cloud cover (IMC) was scattered and infrequent.

Original NASA ASRS Text

Title: BE36 PLT TOOK EVASIVE ACTION TO AVOID A COLLISION WITH INTRUDING ACFT IN ZMA CLASS E.

Narrative: FLYING IFR BOCA RATON (BCT) TO FALCON FIELD (FFC), IN DENSE CLOUD IMC, MY SKYWATCH (TCAS) SHOWED RAPIDLY CLOSING TARGET ON INTERCEPT AT 10 OCLOCK, TARGET FIRST SCOPED AT 3 MILES, 300 FT BELOW. ATTEMPTED CALL TO CTR STEPPED ON. TARGET CLOSED TO 1.5 MILES, 200 FT BELOW WHEN CTR REACHED. I REQUESTED INSTRUCTION REGARDING INTERCEPTING ACFT. CTR DID NOT APPEAR TO UNDERSTAND MY CONCERN. I EXPLAINED THAT TARGET WAS LESS THAN A MILE AND APPARENTLY CLIMBING, ON DIRECT INTERCEPT. AFTER SEVERAL SECONDS WAITING ATC RESPONSE, I INFORMED CTR I WAS INITIATING URGENT 500 FT CLIMB TO THE R SHORTLY AFTERWARD, TARGET PASSED BELOW ME, SHOWING 100 FT BENEATH ON SKYWATCH. CTR INFORMED ME THAT SEPARATION WAS A FULL 500 FT. I REMAINED IN ZERO VISIBILITY (NEVER SAW OTHER ACFT) FOR 3 MORE MINS. RETURNED TO ASSIGNED COURSE WITHIN 5 MINS. I WAS AUDIBLY ALERTED BY TCAS, AND IN ABSENCE OF CLARIFICATION BY CTR, TOOK WHAT I FELT WAS APPROPRIATE AVOIDANCE ACTION IN ZERO VISIBILITY. CTR WAS QUITE BUSY AT THAT TIME, AND CLOUD COVER (IMC) WAS SCATTERED AND INFREQUENT.
