Narrative:

Center descended us to 1000 ft and called traffic 1-2 O'clock 4 mi. We never saw traffic and almost simultaneously received a TA on TCASII followed by RA of about 400 ft climbing right turn. Returned to level flight and told controller we never saw traffic. Once again, he verified traffic was present. After landing I called both center and approach control and they both said our slight deviation presented no problem to them. They again said that traffic was indicated but they were not working him. Electronic cockpits are wonderful when you don't have to make adjustments. But, with continual changes in airspeed, altitude, heading, etc., putting your head back into the cockpit for reprogramming seems extremely stupid as well as unsafe. We need to focus on simply flying the airplane.

Title: MLG HAS TCASII RA. CLBS A DIRECTED BUT NO SIGHTING OF TFC.

Narrative: CTR DSNDED US TO 1000 FT AND CALLED TFC 1-2 O'CLOCK 4 MI. WE NEVER SAW TFC AND ALMOST SIMULTANEOUSLY RECEIVED A TA ON TCASII FOLLOWED BY RA OF ABOUT 400 FT CLBING R TURN. RETURNED TO LEVEL FLT AND TOLD CTLR WE NEVER SAW TFC. ONCE AGAIN, HE VERIFIED TFC WAS PRESENT. AFTER LNDG I CALLED BOTH CTR AND APCH CTL AND THEY BOTH SAID OUR SLIGHT DEV PRESENTED NO PROBLEM TO THEM. THEY AGAIN SAID THAT TFC WAS INDICATED BUT THEY WERE NOT WORKING HIM. ELECTRONIC COCKPITS ARE WONDERFUL WHEN YOU DON'T HAVE TO MAKE ADJUSTMENTS. BUT, WITH CONTINUAL CHANGES IN AIRSPD, ALT, HDG, ETC., PUTTING YOUR HEAD BACK INTO THE COCKPIT FOR REPROGRAMMING SEEMS EXTREMELY STUPID AS WELL AS UNSAFE. WE NEED TO FOCUS ON SIMPLY FLYING THE AIRPLANE.
