Narrative:

During approach to runway 30R at stl airport, after radar vector to localizer runway 30R, we were on localizer runway 30R and close to 2-ENG bizjet on localizer runway 30L. Bizjet started to come close to us and after TCASII TA and then RA and visual situation, we made action according to RA of TCASII climb, crossing climb, and at 3000 ft we were clear of conflict. I think TCASII is a great instrument.
