Narrative:

During a flight training activity; we were in a C172R G1000 equipped; tis (traffic information system) inoperative; heading east (090 degrees). The student was flying a constant airspeed descent from 5500 ft to 3500 ft MSL. At exactly 4500 ft the student yelled and jerked the control wheel left; we had a very near miss with a piper meridian. It was a direct near midair; both aircraft were on a direct collision course. I (the CFI) had my head down programming the GPS; when the student yelled and turned left. I looked up. The other aircraft went 10 ft to the right of the right main wheel and 15 ft below it. The other aircraft made no evasive maneuver to avoid the collision; I believe the pilot of that aircraft never saw ours. If my student had not turned left out of reaction and instead turned right as the aim says; I would not be alive to write about this event.

Narrative: DURING A FLT TRAINING ACTIVITY; WE WERE IN A C172R G1000 EQUIPPED; TIS (TFC INFO SYS) INOP; HDG E (090 DEGS). THE STUDENT WAS FLYING A CONSTANT AIRSPD DSCNT FROM 5500 FT TO 3500 FT MSL. AT EXACTLY 4500 FT THE STUDENT YELLED AND JERKED THE CTL WHEEL L; WE HAD A VERY NEAR MISS WITH A PIPER MERIDIAN. IT WAS A DIRECT NEAR MIDAIR; BOTH ACFT WERE ON A DIRECT COLLISION COURSE. I (THE CFI) HAD MY HEAD DOWN PROGRAMMING THE GPS; WHEN THE STUDENT YELLED AND TURNED L. I LOOKED UP. THE OTHER ACFT WENT 10 FT TO THE R OF THE R MAIN WHEEL AND 15 FT BELOW IT.
