Human Factors
I was providing instrument instruction to a CFII candidate. The student was wearing a view limiting device. We were conducting practice instrument approaches to JNX runways 3 and 21. We were currently on the practice ILS approach to runway 3 at JNX at the time of the intentions.I made an announcement on the CTAF frequency that we were 7 miles out on the practice ILS runway 3 circle to land on 21. We heard another aircraft make an announcement that they were 3 miles away and entering the downwind for runway 21 on a 45 degree entry. The tone of the pilot's voice made me suspect it was a student pilot on a solo flight. The next announcement I made was a 5 mile final for the ILS runway 3 circle to land on 21. The other airplane in the pattern then made an announcement that they were going to join the crosswind for runway 3. I queried the airplane and asked if the pilot was by themselves and got no response. At this time I made the decision to continue the approach to a full stop instead of executing a circling approach. I made an announcement that we were on a 1.5 mile final and that we would be a full stop; at this time I observed the previous mentioned aircraft turn the base leg in front of us. My student was still wearing his view limiting device; I took control of the airplane and executed a missed approach sidestepping to the right of the runway and announcing my intentions on the CTAF too. We rejoined the traffic pattern on the upwind and made a normal approach to landing.
