Narrative:

I was on final approach to runway 23 with a student. We were cleared to land and #1 for the runway. At the time we were being followed by a C150, and a C172RG had just reported 3 mi out. Immediately following the C172RG's report, the pilot in the C150 reported that the C172RG was descending into my aircraft. I leaned forward, looked up and saw the C172RG about 75 ft above us descending directly at us. His rate of descent appeared to be slightly excessive because he was above the VASI glide path which I was on. I immediately began a right turn to avoid the other aircraft. He never saw us. He continued his descent to landing, while we were trying to s-turn to regain separation from the C172RG. We landed uneventfully, but shaken by the incident. I feel that the near miss could have been prevented by a few things. First and foremost, the pilot of the C172RG needs to work on his see and avoid abilities. I had no way of seeing him until he was virtually on top of me. In fact, I may not have seen him at all if the pilot in the C150 hadn't called the traffic. Secondly, I feel the controller could have done a better job. It would have been safer if she had ordered the C172RG to go around, instead of letting him continue. By allowing the C172RG to continue, the controller put me in a difficult, and unsafe position. My greatest suggestion is that the see and avoid concept needs more emphasis in training. I see so many instructors not discuss the topic, or just skim through it. I would like to see a new program that emphasizes see and avoid for all pilots. The program should be something that gets their attention, and makes them realize how important see and avoid really is. Please contact me if you feel this suggestion could be developed further. As an instructor, I would like to play an active role in any such program. My last quick suggestion is the addition of BRITE scopes at VFR airports such as laf, which have high density student training activities.

Title: INSTRUCTOR WITH SPI IN C150 IS ON FINAL APCH WHEN A FOLLOWING C150 ANNOUNCES THAT A C172RG IS DSNDING ON TOP OF THE FIRST ACFT. INSTRUCTOR SIGHTS ACFT AND TAKES EVASIVE ACTION. CTLR TAKES NO ACTION.

Narrative: I WAS ON FINAL APCH TO RWY 23 WITH A STUDENT. WE WERE CLRED TO LAND AND #1 FOR THE RWY. AT THE TIME WE WERE BEING FOLLOWED BY A C150, AND A C172RG HAD JUST RPTED 3 MI OUT. IMMEDIATELY FOLLOWING THE C172RG'S RPT, THE PLT IN THE C150 RPTED THAT THE C172RG WAS DSNDING INTO MY ACFT. I LEANED FORWARD, LOOKED UP AND SAW THE C172RG ABOUT 75 FT ABOVE US DSNDING DIRECTLY AT US. HIS RATE OF DSCNT APPEARED TO BE SLIGHTLY EXCESSIVE BECAUSE HE WAS ABOVE THE VASI GLIDE PATH WHICH I WAS ON. I IMMEDIATELY BEGAN A R TURN TO AVOID THE OTHER ACFT. HE NEVER SAW US. HE CONTINUED HIS DSCNT TO LNDG, WHILE WE WERE TRYING TO S-TURN TO REGAIN SEPARATION FROM THE C172RG. WE LANDED UNEVENTFULLY, BUT SHAKEN BY THE INCIDENT. I FEEL THAT THE NEAR MISS COULD HAVE BEEN PREVENTED BY A FEW THINGS. FIRST AND FOREMOST, THE PLT OF THE C172RG NEEDS TO WORK ON HIS SEE AND AVOID ABILITIES. I HAD NO WAY OF SEEING HIM UNTIL HE WAS VIRTUALLY ON TOP OF ME. IN FACT, I MAY NOT HAVE SEEN HIM AT ALL IF THE PLT IN THE C150 HADN'T CALLED THE TFC. SECONDLY, I FEEL THE CTLR COULD HAVE DONE A BETTER JOB. IT WOULD HAVE BEEN SAFER IF SHE HAD ORDERED THE C172RG TO GAR, INSTEAD OF LETTING HIM CONTINUE. BY ALLOWING THE C172RG TO CONTINUE, THE CTLR PUT ME IN A DIFFICULT, AND UNSAFE POS. MY GREATEST SUGGESTION IS THAT THE SEE AND AVOID CONCEPT NEEDS MORE EMPHASIS IN TRAINING. I SEE SO MANY INSTRUCTORS NOT DISCUSS THE TOPIC, OR JUST SKIM THROUGH IT. I WOULD LIKE TO SEE A NEW PROGRAM THAT EMPHASIZES SEE AND AVOID FOR ALL PLTS. THE PROGRAM SHOULD BE SOMETHING THAT GETS THEIR ATTN, AND MAKES THEM REALIZE HOW IMPORTANT SEE AND AVOID REALLY IS. PLEASE CONTACT ME IF YOU FEEL THIS SUGGESTION COULD BE DEVELOPED FURTHER.
