Logbook hours
How do people fill in their hours in the logbook? Do you use hours or minutes, or decimal?
I have always used decimal, in this format:
0.1 5mins 0.2 10mins 0.3 15mins 0.4 20mins 0.4 25mins 0.5 30mins
0.6 35mins 0.7 40mins 0.7 45mins 0.8 50mins 0.9 55mins 1.0 1hr
...and so on. This method I have always used, and have marked a clear table in the front of my logbook. Having just tried entering a logbook in hours and minutes I have only got about 15hours into my total hours and already the decimal total is out by 20mins, when converting say 16.3 to a hhmm total of 16:15.
This leads to a question. I have now amassed over 600 hours in decimal. When the total flying is less than 30mins it seems I am overcounting my hours, by when the total is more than 30mins per hour I am undercounting it, so it should even out over the hours.
No instructor I have flown with or anyone in the CAA has queried my method.
Can anyone clarify this? Should I carry on using the decimal figures, or run a correction to my total hours at the end of a page and then change my method?
