Aircraft; Equipment / Tooling; Human Factors; Procedure
While descending from FL350 to FL240 as requested by Washington Center; we received a RA from our TCAS system. The auto pilot was disengaged and the descent was stopped. We made visual contact with the other aircraft and we passed above and to the right of the conflicting aircraft. ATC never advised us of a conflict. After the event; we continued the flight with no other problematic events.
Descending per ATC instructions from FL350 to FL240 we heard an aircraft tell ATC that they were descending for a RA. We received a RA at that time and I saw the aircraft coming from my 9 o'clock position and I started following the RA. The Controller questioned the other aircraft. I told my Co-Captain; (pilot not flying) that I had the aircraft and was maneuvering. ATC gave us a vector to the left which would have taken us towards the other aircraft. I maneuvered in that direction keeping the other aircraft in sight till it passed us. We passed approximately 500 FT above and to the left of the other aircraft. I called ATC and advised them that we were returning to our original track on the STAR. We received no response and we advised them again and proceeded to descend to FL240.
Corporate flight crew experienced a TCAS RA descending on a STAR; no traffic information was provided by ATC.
