Narrative:

We were approaching initial approach fix, 240 degree radial, DME arc for ILS runway 13, hut, from the southeast at 3500 ft when I (the instructor) saw the approaching aircraft 12 O'clock position, about 1/2 mi. It seemed to me we would pass safely behind this aircraft. I told the student to look at it. In about 4-5 seconds, we passed, but much closer than I had expected. It startled me and I lifted the right wing. The other aircraft was on a southeast heading. When I lifted the wing, the other aircraft saw us for the first time. The lesson I think I learned here, and the purpose for sending this report, is that if I or any pilot sees another aircraft approaching in close proximity -- evasive action should be executed immediately. A few degrees heading difference of either of our aircraft could have caused a midair collision. We were at the outer edge of wichita approach's radar coverage. Wichita never gave us traffic and shortly after our near miss, we were informed that 'radar contact lost, report established on the approach.' evasive action serves 2 purposes: 1) you avoid the other aircraft, 2) any movement of either aircraft may get the attention of other pilot.

Title: IN A 'SEE AND AVOID' EVENT, PA28 INSTRUCTOR ADVISES STUDENT TO WATCH AS A CONVERGING, SAME ALT CONFLICT IS DEVELOPING. EVENT STARTLES INSTRUCTOR.

Narrative: WE WERE APCHING INITIAL APCH FIX, 240 DEG RADIAL, DME ARC FOR ILS RWY 13, HUT, FROM THE SE AT 3500 FT WHEN I (THE INSTRUCTOR) SAW THE APCHING ACFT 12 O'CLOCK POS, ABOUT 1/2 MI. IT SEEMED TO ME WE WOULD PASS SAFELY BEHIND THIS ACFT. I TOLD THE STUDENT TO LOOK AT IT. IN ABOUT 4-5 SECONDS, WE PASSED, BUT MUCH CLOSER THAN I HAD EXPECTED. IT STARTLED ME AND I LIFTED THE R WING. THE OTHER ACFT WAS ON A SE HEADING. WHEN I LIFTED THE WING, THE OTHER ACFT SAW US FOR THE FIRST TIME. THE LESSON I THINK I LEARNED HERE, AND THE PURPOSE FOR SENDING THIS RPT, IS THAT IF I OR ANY PLT SEES ANOTHER ACFT APCHING IN CLOSE PROX -- EVASIVE ACTION SHOULD BE EXECUTED IMMEDIATELY. A FEW DEGS HEADING DIFFERENCE OF EITHER OF OUR ACFT COULD HAVE CAUSED A MIDAIR COLLISION. WE WERE AT THE OUTER EDGE OF WICHITA APCH'S RADAR COVERAGE. WICHITA NEVER GAVE US TFC AND SHORTLY AFTER OUR NEAR MISS, WE WERE INFORMED THAT 'RADAR CONTACT LOST, RPT ESTABLISHED ON THE APCH.' EVASIVE ACTION SERVES 2 PURPOSES: 1) YOU AVOID THE OTHER ACFT, 2) ANY MOVEMENT OF EITHER ACFT MAY GET THE ATTN OF OTHER PLT.
