Jeppesen quickly responded to the September 5 alert about the unscheduled September 4 JeppFD iPad update that reportedly destroyed the application’s terminal approach charts in the process of adding new data. The error occurred when the “update in progress” message appeared on the update screen. Jeppesen told NBAA on September 6 that the update was actually intended for the demonstration side of the JeppFD system and was released in error. Affected users were able to restore the app to normal, by performing a deactivate and a quick reactivate of their device to re-establish the their correct charting services.
