It was a late flight and both of us were getting tired from the long day. It was leg three plus I had commuted by air to start the day. The total flight was 3 hours. Everything went great until we were cleared for the approach. It was hazy with a visibility of 5 miles. I was looking for the runway but because our windows were fogged up more than usual I could not see very well. As I armed the approach I did not realize I had the VOR; not the ILS tuned as the active frequency. It was in the backup. As I looked at the FMA; I noticed it had VAPP instead of LOC. I finally saw the runway while still on the initial heading the Controller had given to us and by that time--as I tried to turn--the Controller cancelled our approach clearance and we were vectored back around. Because the LOC was not tuned; nothing was ever captured. It was very late and both the Captain and I were very tired from the day. We should have been more vigilant; checked and cross checked everything more than usual. Someone could have been landing on the parallel runway and that would have been an even bigger issueLearn to check everything 10x more when you are very tired with late flights. You may catch something new each time you cross check. Be sure the correct frequencies are in the right position to be armed.
A fatigued EMB-145 flight crew on a vector to intercept the LOC failed to notice their ILS frequency was not selected as active and they through the LOC and may have infringed on the parallel runway approach. The error was noted by ATC and the flight re-sequenced to a safe landing. A prior commute to work was cited by the reporter as a contributing fatigue factor.
