Narrative:

We had departed den for slc. It was a perfectly clear day east of the mountains. We were on radar vectors, having come off runway 35L at den. We had flown the runway heading (352 degree radial) and had now been turned to a westerly heading and cleared to 12000 ft MSL. The airplane was light and climbing well. We were just leveling at 12000 ft when we got an RA to climb. We did, and as we were passing about 12500 ft, we saw another aircraft in front of us on the way down, also responding to an RA. We estimated clearance at about 1/2 mi. We leveled at 13000 ft and told departure what had occurred. As I understand how TCASII works, it did just what it was programmed to do. We were climbing and the other aircraft was descending and TCASII had no way to know we were both planning to level 1000 ft apart. It was supposed to keep us from colliding, and it did, admirably.

Title: ACR ON CLB OUT HAS TCASII RA.

Narrative: WE HAD DEPARTED DEN FOR SLC. IT WAS A PERFECTLY CLR DAY E OF THE MOUNTAINS. WE WERE ON RADAR VECTORS, HAVING COME OFF RWY 35L AT DEN. WE HAD FLOWN THE RWY HDG (352 DEG RADIAL) AND HAD NOW BEEN TURNED TO A WESTERLY HDG AND CLRED TO 12000 FT MSL. THE AIRPLANE WAS LIGHT AND CLBING WELL. WE WERE JUST LEVELING AT 12000 FT WHEN WE GOT AN RA TO CLB. WE DID, AND AS WE WERE PASSING ABOUT 12500 FT, WE SAW ANOTHER ACFT IN FRONT OF US ON THE WAY DOWN, ALSO RESPONDING TO AN RA. WE ESTIMATED CLRNC AT ABOUT 1/2 MI. WE LEVELED AT 13000 FT AND TOLD DEP WHAT HAD OCCURRED. AS I UNDERSTAND HOW TCASII WORKS, IT DID JUST WHAT IT WAS PROGRAMMED TO DO. WE WERE CLBING AND THE OTHER ACFT WAS DSNDING AND TCASII HAD NO WAY TO KNOW WE WERE BOTH PLANNING TO LEVEL 1000 FT APART. IT WAS SUPPOSED TO KEEP US FROM COLLIDING, AND IT DID, ADMIRABLY.
