Hey,
I was on a flight from SCAD - SCAT and I received a PF3 Error Detected message approx 20-30 mins into the flight. Nothing special going on when the error occurred. During climb, I had been told to check position, that I was 2 miles off the airway, but I was dead on the course line. I was then cleared to my final cruise altitude of FL180. No other issues prior to error. I tried to send the file via the error msg page but it kept timing out. I'm curious to know what caused the error to happen.
Thanks,
Tony J
