Nexus 7 (2013) V9.0.31 - I would like to suggest again an additional instrument, a ‘Total Flight Time’ timer. This would not reset to zero automatically upon takeoff as the current ‘Flight Duration’ timer does. It would have to be manually reset in the same manner as the current ‘Flight Duration’ one is. As I fly around stopping at different airports in a day’s flying, this new instrument at the end of the day would indicate my total flying time for the day. It should retain its value through multiple ‘Exit Application’ cycles and device shutdown cycles as the current timer does. I personally would find this useful.
