That probably would not occur to me during the stress of an exam.

and even if it wasnt a nice round number , didnt you ever learn long
devision in primary school?

Yes, long ago. I never liked it, and I did it with pencil and paper, not in

Personally I do most of my flight planning in Excel. but if I havent got a
computer with me, I always have a calculator in my flight bag.

I guess nobody uses slide rules any more.
