Narrative:

After crossing the TA radio beacon in the soviet far east, our omega did not turn on airway A81 nebound. Our heading remained 091 degrees for about 20 mi until we noticed we were off course. We immediately made a left turn to correct the problem and within 10 NM, we were back on course on the 067 degree bearing on A81 to ma (the next fix). We should have monitored the omega more closely, but, since the captain had never used the omega except for this trip, and I have not used it for 5 yrs, I think our company should provide more training.
