Narrative:

The flight was being vectored by approach because sps VOR was OTS. Last assigned altitude was 3000 ft MSL and on radar vectors, heading 360 degrees. At the approximately location of the sps VOR, the flight was assigned a 090 degree heading, and ATC asked if the sps airport was in sight. The first officer replied that it was, and the flight was subsequently cleared for the visual approach to runway 17. I commanded the autoplt to turn to a 090 degree heading, and began a descent to 2300 ft MSL, the published altitude for the visual approach. As the aircraft heading passed through 070 degrees, and at an altitude of 2800 ft, ATC said that we had military training traffic just off our right, and that we should immediately turn back to 360 degrees. The TCASII then gave an RA to descend, and the descent rate was increased to comply with the red arc on the vsi. About 5 seconds later, the GPWS gave a terrain warning, and the descent rate was arrested. The first officer reported seeing the traffic pass overhead. I suggest that if airline operations are to continue into this airport, the training aircraft need to be segregated from the airliners properly, and ATC needs further training as to the maneuverability of large aircraft.

Title: A COMMUTER ACFT MAKING A VISUAL APCH GETS A TCASII RA FROM A MIL TRAINER ACFT AND A GPWS ALERT DUE TO STEEP DSCNT.

Narrative: THE FLT WAS BEING VECTORED BY APCH BECAUSE SPS VOR WAS OTS. LAST ASSIGNED ALT WAS 3000 FT MSL AND ON RADAR VECTORS, HDG 360 DEGS. AT THE APPROX LOCATION OF THE SPS VOR, THE FLT WAS ASSIGNED A 090 DEG HDG, AND ATC ASKED IF THE SPS ARPT WAS IN SIGHT. THE FO REPLIED THAT IT WAS, AND THE FLT WAS SUBSEQUENTLY CLRED FOR THE VISUAL APCH TO RWY 17. I COMMANDED THE AUTOPLT TO TURN TO A 090 DEG HDG, AND BEGAN A DSCNT TO 2300 FT MSL, THE PUBLISHED ALT FOR THE VISUAL APCH. AS THE ACFT HDG PASSED THROUGH 070 DEGS, AND AT AN ALT OF 2800 FT, ATC SAID THAT WE HAD MIL TRAINING TFC JUST OFF OUR R, AND THAT WE SHOULD IMMEDIATELY TURN BACK TO 360 DEGS. THE TCASII THEN GAVE AN RA TO DSND, AND THE DSCNT RATE WAS INCREASED TO COMPLY WITH THE RED ARC ON THE VSI. ABOUT 5 SECONDS LATER, THE GPWS GAVE A TERRAIN WARNING, AND THE DSCNT RATE WAS ARRESTED. THE FO RPTED SEEING THE TFC PASS OVERHEAD. I SUGGEST THAT IF AIRLINE OPS ARE TO CONTINUE INTO THIS ARPT, THE TRAINING ACFT NEED TO BE SEGREGATED FROM THE AIRLINERS PROPERLY, AND ATC NEEDS FURTHER TRAINING AS TO THE MANEUVERABILITY OF LARGE ACFT.
