100 out of every 5 eh.
Is that the same as "There are 10 kinds of people, those that understand binary and those that don't"?
Also, is it still necessary to use a whizz wheel to get through the Nav ground school? I thought that I was given the choice of whizz wheel or electronic when I was going through it. I still chose the whizz wheel as I was a bit nostalgic for my old slide rule, electronic calculators were just being accepted when I did A level physics and no one could afford them when I did my O levels.
G-MYMH.
