Human Factors; Procedure
While flying the DUMPY Arrival to DAL; we were given a clearance to cross CQY at 10;000 feet; and ORVIL at 9;000 feet. Passing through approximately 13;000 feet; Center gave us traffic at 12 o'clock; a Lear jet climbing VFR. Almost immediately we got a climb RA. This was the most aggressive RA I have ever seen; calling for 2;500 to 3;000 FPM. I disengaged the autopilot and followed the RA. It momentarily went to monitor Vertical Speed; [and] then went back to the aggressive climb RA; which we followed. We climbed back to nearly 13;000 feet complying with the RA. ATC was talking to the Lear. I feel he should have amended our descent instructions.
We were cleared to cross CQY at 10;000 feet. Approaching CQY; at approximately 11;000 feet we got a significant RA commanding 2-3;000 FPM climb. We complied and the RA lowered to approximately 1;500 FPM. We complied; at which time the RA increased to 2-3;000 FPM again. We complied. When clear of conflict; we told ATC who informed us that there was a VFR Lear jet at 10;400 feet. I said maybe having us cross CQY at 10;000 feet with that traffic there wasn't the safest thing. He said he hadn't 'been able to get back' to the Lear jet who was climbing VFR. I think he just didn't notice the impending conflict. He should have stopped the Lear if the Lear was talking to him; or at least stopped our descent. Heck; he never even called out the traffic to us. It was the most severe RA I've ever seen commanded.
Air carrier arrival into DAL experienced a significant TCAS RA event with a VFR climbing Lear jet; the reporter questioning ATC handling.
