I used to log it in square root format.

I utilized the decimal system when I was a GA pilot doing flight instructing and corporate. When I got hired with the airlines, I converted it to hours:minutes.

I like the accuracy and the ability to crosscheck the airline's system on our online schedules.


Adding the logbook up takes a few more minutes than the simple decimals, but I think it looks sharper and is easier to track.


To add a 4+12 flight and 3+22 flight.... 4+(12/60+3+(22/60)= 7.xxxxxxxxxxx... Take that answer, subtract 7 and multiple the resulting decimal by 60 and you have your minutes. Complicated, yes. But... I'm OCD. :)

Why circles? Was you foot nailed to the floor while you were having that Pi fight with the clowns?:D

I use the dewey decimal system...is that wrong?

Good lordy, I just got back from a 5 day, and this thread is still going. Can I pose the real hard hitting questions or what?

we should have adopted the metric system long ago...makes so much more sense. however, one thing; are we going to change our folk sayings? i.e. "if you give a kid a centimeter, he'll take a kilometer" :D
