Narrative:

Student and I departed local airport for purpose of practicing the ILS at miv. The WX was 4 mi visibility, through haze, scattered climb above 3000' AGL. After being released from den AFB approach we contacted miv FSS for traffic advisories. Said local traffic in the pattern. No mention of other aircraft on any of the approachs. Intercepted localizer, student under the hood, tracked inbound stating our intentions to miv FSS. About 1 mi from the OM I spotted another small aircraft coming straight at us tracking outbnd on the localizer. I quickly turned the aircraft to the left and downwind. The other aircraft made no evasive maneuver. I assume the pilot did not see us. We broke off the approach and did one turn in holding--a direct entry--while the other small aircraft proceeded in doing a parallel entry. We proceeded behind the small aircraft who continued the approach gain, with no radio calls. For another hour we would repeatedly spot this aircraft in different phases of approach and we continued to maintain VFR sep. What I gather from this is: 1) I should have been more vigilant outside instead of being totally absorbed with my student's approach. 2) I probably was lulled into a false sense of security by hearing from miv FSS that there was no reported traffic in the area. 3) never count on the other plane to see you first. If I had not looked up at that exact time, I wouldn't be here writing this. 4) against a hazy background, aircraft that are painted white are the most difficult to see. Perhaps some of the flight schools will one day decide to paint their aircraft another type of color--maybe those 'day-glo' colors that all the skateboard kids like to wear. It would sure brighten up my day.

Title: FLT INSTRUCTOR DOING INS TRAINING HAS NMAC WITH OPPOSITE DIRECTION TRAFFIC ON ILS APCH.

Narrative: STUDENT AND I DEPARTED LCL ARPT FOR PURPOSE OF PRACTICING THE ILS AT MIV. THE WX WAS 4 MI VISIBILITY, THROUGH HAZE, SCATTERED CLB ABOVE 3000' AGL. AFTER BEING RELEASED FROM DEN AFB APCH WE CONTACTED MIV FSS FOR TFC ADVISORIES. SAID LCL TFC IN THE PATTERN. NO MENTION OF OTHER ACFT ON ANY OF THE APCHS. INTERCEPTED LOC, STUDENT UNDER THE HOOD, TRACKED INBND STATING OUR INTENTIONS TO MIV FSS. ABOUT 1 MI FROM THE OM I SPOTTED ANOTHER SMA COMING STRAIGHT AT US TRACKING OUTBND ON THE LOC. I QUICKLY TURNED THE ACFT TO THE LEFT AND DOWNWIND. THE OTHER ACFT MADE NO EVASIVE MANEUVER. I ASSUME THE PLT DID NOT SEE US. WE BROKE OFF THE APCH AND DID ONE TURN IN HOLDING--A DIRECT ENTRY--WHILE THE OTHER SMA PROCEEDED IN DOING A PARALLEL ENTRY. WE PROCEEDED BEHIND THE SMA WHO CONTINUED THE APCH GAIN, WITH NO RADIO CALLS. FOR ANOTHER HR WE WOULD REPEATEDLY SPOT THIS ACFT IN DIFFERENT PHASES OF APCH AND WE CONTINUED TO MAINTAIN VFR SEP. WHAT I GATHER FROM THIS IS: 1) I SHOULD HAVE BEEN MORE VIGILANT OUTSIDE INSTEAD OF BEING TOTALLY ABSORBED WITH MY STUDENT'S APCH. 2) I PROBABLY WAS LULLED INTO A FALSE SENSE OF SECURITY BY HEARING FROM MIV FSS THAT THERE WAS NO RPTED TFC IN THE AREA. 3) NEVER COUNT ON THE OTHER PLANE TO SEE YOU FIRST. IF I HAD NOT LOOKED UP AT THAT EXACT TIME, I WOULDN'T BE HERE WRITING THIS. 4) AGAINST A HAZY BACKGROUND, ACFT THAT ARE PAINTED WHITE ARE THE MOST DIFFICULT TO SEE. PERHAPS SOME OF THE FLT SCHOOLS WILL ONE DAY DECIDE TO PAINT THEIR ACFT ANOTHER TYPE OF COLOR--MAYBE THOSE 'DAY-GLO' COLORS THAT ALL THE SKATEBOARD KIDS LIKE TO WEAR. IT WOULD SURE BRIGHTEN UP MY DAY.
