Narrative:

During airwork, alternating 30 degree bank turns with 90-180 degree heading changes, my tcad alerted me to another aircraft in my airspace. It indicated 500 ft altitude separation and 2.1 mi lateral. I began to scan my flight path for any conflicts. I spotted the beech 1900 at about 1 O'clock low. We did indeed have an altitude separation (estimate 500 ft) and the closest we passed laterally was 1/2 mi.

Narrative: DURING AIRWORK, ALTERNATING 30 DEG BANK TURNS WITH 90-180 DEG HDG CHANGES, MY TCAD ALERTED ME TO ANOTHER ACFT IN MY AIRSPACE. IT INDICATED 500 FT ALT SEPARATION AND 2.1 MI LATERAL. I BEGAN TO SCAN MY FLT PATH FOR ANY CONFLICTS. I SPOTTED THE BEECH 1900 AT ABOUT 1 O'CLOCK LOW. WE DID INDEED HAVE AN ALT SEPARATION (ESTIMATE 500 FT) AND THE CLOSEST WE PASSED LATERALLY WAS 1/2 MI.
