Narrative:

During climb out from mdt, we were given 8000 ft altitude assignment. Nearing 5000 ft departure told us to maintain 5000 ft for a single engine light aircraft at about 6000 ft VFR. We leveled at 5000 ft and then I reported traffic. Departure then told us to climb and maintain 8000 ft. As we climbed we had a TA then an RA from TCASII. The other aircraft was in sight the entire time and passed vertical and horizontal as stated above. We ignored the RA since the aircraft was in sight and passed behind us.

Title: ACR FLC RECEIVED TCASII RA BUT DID NOT RESPOND BECAUSE ACFT WAS 'IN SIGHT.'

Narrative: DURING CLBOUT FROM MDT, WE WERE GIVEN 8000 FT ALT ASSIGNMENT. NEARING 5000 FT DEP TOLD US TO MAINTAIN 5000 FT FOR A SINGLE ENG LIGHT ACFT AT ABOUT 6000 FT VFR. WE LEVELED AT 5000 FT AND THEN I RPTED TFC. DEP THEN TOLD US TO CLB AND MAINTAIN 8000 FT. AS WE CLBED WE HAD A TA THEN AN RA FROM TCASII. THE OTHER ACFT WAS IN SIGHT THE ENTIRE TIME AND PASSED VERT AND HORIZ AS STATED ABOVE. WE IGNORED THE RA SINCE THE ACFT WAS IN SIGHT AND PASSED BEHIND US.
