Narrative:

On a scheduled flight from mco to mia, we were on the heatt 5 arrival, level at 8000 ft. We were told to switch frequencys from ZMA to mia approach. Before the captain had the chance to check in, the tcasi indicated a TA. The captain and I both spotted the climbing traffic. I then made a shallow bank to the right for about 10-20 degrees to allow for more spacing. The captain called ATC and notified them of the TA. They told us that the falcon jet was supposed to be at 7000 ft. They also said that they lost radar contact on him, and regained radar contact at 6900 ft, and stated that those were the signs of the falcon turning the transponder off. If we did not have the tcasi it may have been even closer. I also think that more training could be put into the recognition of altdevs and TA's.

Title: BE190 CREW HAD A TCASII TA IN MIA CLASS B AIRSPACE.

Narrative: ON A SCHEDULED FLT FROM MCO TO MIA, WE WERE ON THE HEATT 5 ARR, LEVEL AT 8000 FT. WE WERE TOLD TO SWITCH FREQS FROM ZMA TO MIA APCH. BEFORE THE CAPT HAD THE CHANCE TO CHK IN, THE TCASI INDICATED A TA. THE CAPT AND I BOTH SPOTTED THE CLBING TFC. I THEN MADE A SHALLOW BANK TO THE R FOR ABOUT 10-20 DEGS TO ALLOW FOR MORE SPACING. THE CAPT CALLED ATC AND NOTIFIED THEM OF THE TA. THEY TOLD US THAT THE FALCON JET WAS SUPPOSED TO BE AT 7000 FT. THEY ALSO SAID THAT THEY LOST RADAR CONTACT ON HIM, AND REGAINED RADAR CONTACT AT 6900 FT, AND STATED THAT THOSE WERE THE SIGNS OF THE FALCON TURNING THE XPONDER OFF. IF WE DID NOT HAVE THE TCASI IT MAY HAVE BEEN EVEN CLOSER. I ALSO THINK THAT MORE TRAINING COULD BE PUT INTO THE RECOGNITION OF ALTDEVS AND TA'S.
