Narrative:
I was in copilot seat of small aircraft with INS student in pilot seat with hood on. Our aircraft was heading 030 degrees toward saf VOR at 9000', preparing to commence a practice VOR approach to saf. Upon crossing the VOR, I looked up to my right and saw an small transport jet aircraft on a collision course (approaching VOR on an approximately heading of 330 degrees). Jet appeared to have flaps down. I took control of our aircraft and made a diving left turn to avoid the small transport jet. If the jet saw us or took evasive action, it was after I evaded. I do not believe that he ever saw us. Both aircraft were in contact with saf tower. Saf tower has no radar. Training traffic was fairly heavy at the time. I believe tower was working about 4-6 aircraft. Saf tower attempts to separate aircraft visually with binoculars are not very accurate! They (tower) often lose track of traffic locations through no fault of theirs. They don't have the tools (radar) to control the situation. Lots of radio air time is spent repeating what 1 aircraft says and relaying it to the other aircraft when all are on the same frequency. With 4-6 aircraft in the area, this repetition defeats the purpose. The communications slip rapidly into the non real-time mode. Need either better training or radar!

Title: INSTRUCTOR IN COPLT SEAT ON PRACTICE IFR APCH IN CLEAR WX TOOK EVASIVE ACTION TO MISS AN SMT JET ALSO ON APCH.
Narrative: I WAS IN COPLT SEAT OF SMA WITH INS STUDENT IN PLT SEAT WITH HOOD ON. OUR ACFT WAS HDG 030 DEGS TOWARD SAF VOR AT 9000', PREPARING TO COMMENCE A PRACTICE VOR APCH TO SAF. UPON XING THE VOR, I LOOKED UP TO MY RIGHT AND SAW AN SMT JET ACFT ON A COLLISION COURSE (APCHING VOR ON AN APPROX HDG OF 330 DEGS). JET APPEARED TO HAVE FLAPS DOWN. I TOOK CTL OF OUR ACFT AND MADE A DIVING LEFT TURN TO AVOID THE SMT JET. IF THE JET SAW US OR TOOK EVASIVE ACTION, IT WAS AFTER I EVADED. I DO NOT BELIEVE THAT HE EVER SAW US. BOTH ACFT WERE IN CONTACT WITH SAF TWR. SAF TWR HAS NO RADAR. TRNING TFC WAS FAIRLY HEAVY AT THE TIME. I BELIEVE TWR WAS WORKING ABOUT 4-6 ACFT. SAF TWR ATTEMPTS TO SEPARATE ACFT VISUALLY WITH BINOCULARS ARE NOT VERY ACCURATE! THEY (TWR) OFTEN LOSE TRACK OF TFC LOCATIONS THROUGH NO FAULT OF THEIRS. THEY DON'T HAVE THE TOOLS (RADAR) TO CTL THE SITUATION. LOTS OF RADIO AIR TIME IS SPENT REPEATING WHAT 1 ACFT SAYS AND RELAYING IT TO THE OTHER ACFT WHEN ALL ARE ON THE SAME FREQ. WITH 4-6 ACFT IN THE AREA, THIS REPETITION DEFEATS THE PURPOSE. THE COMS SLIP RAPIDLY INTO THE NON REAL-TIME MODE. NEED EITHER BETTER TRNING OR RADAR!
