Airspace Structure; Procedure; Company Policy
We encountered a Resolution Advisory while descending through 31;000 feet prior to NAVEE intersection on the HUSTN TWO arrival into KCLT. As the pilot monitoring; I turned off the flight directors; and the pilot flying turned off the auto-pilot to respond to a 'descend' command from the RA. A gulfstream on a flight test had experienced a rapid decompression and was descending on top of us from our 10 o'clock position. The guidance from the TCAS system saved us from a traffic conflict. We advised ATC; and after we were 'clear of conflict;' we proceeded to CLT without further incident. Training and the system worked perfectly.
