Narrative:
On a downwind vector, IMC, 10000 ft from slc approach control, we got a TCASII TA followed by an RA to 'climb.' I added power and climbed to comply with the RA up to 10500 ft where we got a 'monitor vertical speed.' we advised approach control we were climbing for traffic avoidance. Then after a 'clear of conflict' we descended back down to 10000 ft, the original vector altitude.

Title: FLC OF B727 HAS TCASII RA AND RESPONDS BY CLBING, THEN RETURNS TO ASSIGNED ALT.
Narrative: ON A DOWNWIND VECTOR, IMC, 10000 FT FROM SLC APCH CTL, WE GOT A TCASII TA FOLLOWED BY AN RA TO 'CLB.' I ADDED PWR AND CLBED TO COMPLY WITH THE RA UP TO 10500 FT WHERE WE GOT A 'MONITOR VERT SPD.' WE ADVISED APCH CTL WE WERE CLBING FOR TFC AVOIDANCE. THEN AFTER A 'CLR OF CONFLICT' WE DSNDED BACK DOWN TO 10000 FT, THE ORIGINAL VECTOR ALT.
