Narrative:

While on an approach control vector to runway 22R at ord, heading 360 degree at 7000 ft, we got a TA on TCASII followed immediately by 'climb, climb' and a 2000 FPM climb indication on our TCASII climb indicator. As we started an immediate climb, we saw an small transport in a steep right turn to a westerly heading. I believe the small transport got as close as 1 mi horizontal from our aircraft. At approximately 7400 ft we got 'clear of conflict' and started back to 7000 ft. The controller later told us the aircraft was checking TCASII and that we did what we were supposed to. Later he told us that he should have told us the aircraft was there. Later the chief of quality assurance at approach said that they didn't have to tell us when an aircraft was within 500 ft of our altitude. I think today's conduct by the FAA is the most reprehensible and dangerous to date.

Title: AN ACR LGT REACTED TO TCASII AND CLBED WHILE ON APCH TO ORD.

Narrative: WHILE ON AN APCH CTL VECTOR TO RWY 22R AT ORD, HDG 360 DEG AT 7000 FT, WE GOT A TA ON TCASII FOLLOWED IMMEDIATELY BY 'CLB, CLB' AND A 2000 FPM CLB INDICATION ON OUR TCASII CLB INDICATOR. AS WE STARTED AN IMMEDIATE CLB, WE SAW AN SMT IN A STEEP R TURN TO A WESTERLY HDG. I BELIEVE THE SMT GOT AS CLOSE AS 1 MI HORIZ FROM OUR ACFT. AT APPROX 7400 FT WE GOT 'CLR OF CONFLICT' AND STARTED BACK TO 7000 FT. THE CTLR LATER TOLD US THE ACFT WAS CHKING TCASII AND THAT WE DID WHAT WE WERE SUPPOSED TO. LATER HE TOLD US THAT HE SHOULD HAVE TOLD US THE ACFT WAS THERE. LATER THE CHIEF OF QUALITY ASSURANCE AT APCH SAID THAT THEY DIDN'T HAVE TO TELL US WHEN AN ACFT WAS WITHIN 500 FT OF OUR ALT. I THINK TODAY'S CONDUCT BY THE FAA IS THE MOST REPREHENSIBLE AND DANGEROUS TO DATE.
