Date Errors in IGC Files from GPS Flight Recorders

The IGC GNSS Flight Recorder Approval Committee (GFAC) has issued an advisory notice recommending that owners of GPS flight recorders (FRs), especially older designs, switch the device on at regular intervals when not in use. This will keep the GPS receiver and FR batteries from running down and thus minimise the possibility of incorrect dates being recorded when the FR is next used. More information, including the background to the problem is in the advisory notice..
