Narrative:

While conducting an instrument competency check, I was unable to identify the ILS 24 at isp on navigation #1 and navigation #2. Further investigation revealed that the ADF was also inoperative. At this point I alerted ATC of my situation. The controller asked if I would like to declare an emergency at this time. Since I was in IMC, I said yes. ATC gave me vectors to the approach end of 24 at isp, at which time I broke out of the clouds and landed at isp visually. The ATC system worked extremely well and this was an excellent learning experience for myself and my student.

AT THIS POINT I ALERTED ATC OF MY SITUATION. THE CTLR ASKED IF I WOULD LIKE TO DECLARE AN EMER AT THIS TIME. SINCE I WAS IN IMC, I SAID YES. ATC GAVE ME VECTORS TO THE APCH END OF 24 AT ISP, AT WHICH TIME I BROKE OUT OF THE CLOUDS AND LANDED AT ISP VISUALLY. THE ATC SYS WORKED EXTREMELY WELL AND THIS WAS AN EXCELLENT LEARNING EXPERIENCE FOR MYSELF AND MY STUDENT.
