I was wondering if my flight recorder was effected by the GPS recent outage so I plugged it in and noticed that it took a long time for the light to start blinking. Now its a very thick cloudy day today but it concerned me. What are the indicators of date problems with the GPS issues. I do plug the recorder in to charge the battery every 4-6 weeks and had the unit rebuilt a couple years ago.

Download an igc file and check the date.
