Airport; Procedure; Human Factors
On this flight I was Student Pilot; with one student on the back seat and the flight instructor on the right seat. After a normal approach followed by a normal touch and go; we extended our upwind for a 3000 ft MSL glide approach. I called on the radio frequency 'Airport Traffic; Bonanza; extending upwind for a 3000 foot MSL glide approach for runway 17; Airport' After the call the Cessna said that it is right over the field at 3000 ft for a midfield crossing and a 45 degree entry to right traffic for runway 17. In the turn to crosswind we got the aircraft in sight and the IP told them so and that we are on a crosswind for the glide approach. After the turn on Downwind the traffic was at our 12 o'clock position but far away. The IP called the aircraft on the Radio said that we have them in sight and that we are on a high downwind for a glide approach for runway 17. After that everything continued as normal. I called turning on right high base for a glide approach runway 17. The traffic called that it was on right downwind for runway 17. Next I started the turn onto final and said on the radio that we are turning to final for a glide approach runway 17. After I was established on final I was working to hold the correct glide path and was very focused on the glide to the runway. Then the TCAD warning sounded 'Traffic; 3 o'clock less than 1 mile; same altitude'.After the words 'Traffic 3 o'clock' from the TCAD I turned my head to the right and got the traffic in sight heading right to us and very close to us. At this point the IP had already started counter action and I saw him adding full throttle and pulling the airplane into a left turning climb out of the way of the aircraft making a go around. After that we flew on runway heading and intercepted the upwind and reset everything. The Cessna continued its approach to a full stop landing.
After touch & go we reported the extended upwind for 3000 ft MSL glide approach for Runway 17. Then a Cessna reported midfield crossing for 45 degree entry right traffic pattern Runway 17. We reported our turns into high right crosswind; high right downwind and high right base Runway 17. All with the additional 'glide approach'. I think on the high base in the glide approach the Cessna reported right downwind Runway 17. We reported turning final Runway 17 glide approach. The workload for the Pilot flying was high and the IP was talking the SP through the technique.I was on the backseat watching the SP doing his adjustments. At about 500 ft AGL on a stable final a TCAD Warning announced. 'Traffic; 3 o'clock; same altitude; less than 1 mile'. I am not sure; but I think at exact that moment the Cessna reported turning base. I looked right; when the '3 o'clock and saw a really close Cessna turning directly into our flight path. I am pretty sure that it would have led to a mid-air collision; if we wouldn't have taken evasive action.I was about to shout really loud; but the IP saw the traffic half a second before I did; immediately pushed full throttle; turned left and climbed out. I am not too sure about the following conversation but the IP told the Cessna in  CTAF Frequency: You turned directly into our final. Cessna: Get off the radio's. IP: Learn to fly. Cessna: Come on the ground and we will fight that out. We leveled out and calmed down. The Cessna landed normally and we continued our lesson about 3 minutes later. The close traffic was shocking for everybody on board.
