Narrative:

Flying in cruise at 4000 ft MSL under new york approach control. I saw an aircraft on TCASII and got a TA. New york approach did not report the traffic and was too busy to get a word in to ask for a change in altitude or heading. I watched for the RA which was imminent and climbed from 4000 ft to 4400 ft before the 'clear of conflict' notice from TCASII. New york advised of the traffic as I was climbing. I reported the TCASII RA and descended back to 4000 ft MSL. No further problem. Ctrs or approach controls seem to report conflicting traffic when they're right on top of you and it's too late. There is a delay somewhere between identify to notification. Conflicting traffic should be reported sooner! When they call traffic a mi away it's usually a few hundred ft. Maybe 3 mi would suffice?

Title: COMMUTER ACFT HAS TCASII RA, RESPONDS.

Narrative: FLYING IN CRUISE AT 4000 FT MSL UNDER NEW YORK APCH CTL. I SAW AN ACFT ON TCASII AND GOT A TA. NEW YORK APCH DID NOT RPT THE TFC AND WAS TOO BUSY TO GET A WORD IN TO ASK FOR A CHANGE IN ALT OR HDG. I WATCHED FOR THE RA WHICH WAS IMMINENT AND CLBED FROM 4000 FT TO 4400 FT BEFORE THE 'CLR OF CONFLICT' NOTICE FROM TCASII. NEW YORK ADVISED OF THE TFC AS I WAS CLBING. I RPTED THE TCASII RA AND DSNDED BACK TO 4000 FT MSL. NO FURTHER PROB. CTRS OR APCH CTLS SEEM TO RPT CONFLICTING TFC WHEN THEY'RE RIGHT ON TOP OF YOU AND IT'S TOO LATE. THERE IS A DELAY SOMEWHERE BTWN IDENT TO NOTIFICATION. CONFLICTING TFC SHOULD BE RPTED SOONER! WHEN THEY CALL TFC A MI AWAY IT'S USUALLY A FEW HUNDRED FT. MAYBE 3 MI WOULD SUFFICE?
