What kind of flight log do you use?
Is there an app you like or just a hard copy book?
I created a log in a spiral ring binder. Made (4) sections with dividers and labeled them:
1. Flight: With columns for Date, Flt #, Location, Purpose, Conditions, Start/Stop Time, Duration, Battery #, Notes
2. Firmware & Calibration: With columns for Date, Device, Action Performed
3. Maintenance: With columns for Date, Device, Action Performed
4. Batteries: With columns for Date, Battery #, Flight #, Action Performed, (flew, charged, etc)
I prefer a written log to an app. If they want/need to, the FAA can subpoena your records and that would involve losing your electronic device, if they were stored on that.
